Baltimore Online Guitar Lessons Vs Private Guitar Lessons

The Gibson Les Paul is a solid body electric guitar that was first sold by the Gibson Guitar Corporation in 1952.[1] The Les Paul was designed by Gibson president Ted McCarty, factory manager John Huis and their team, along with guitarist/inventor Les Paul.

The Les Paul was originally offered with a gold finish and two P-90 pickups. In 1957, humbucking pickups were added, along with sunburst finishes in 1958. The sunburst 1958–1960 Les Paul – today one of the best-known electric guitar types in the world – was considered a failure, with low production and sales. For 1961, the Les Paul was redesigned into what is now known as the Gibson SG. This design continued as a separate guitar when the traditional single cutaway, carved top bodystyle was re-introduced in 1968. The Les Paul has been continually produced in countless versions and editions since. Along with Fender's Telecaster and Stratocaster, it was one of the first mass-produced electric solid-body guitars. Les Pauls have been used in many genres, including rock, country, pop, soul, rhythm and blues, blues, jazz, reggae, punk, and heavy metal.

Les Paul and "Clunker" (1947) ES-150 (1936)

In 1950, the ancestors of Fender Telecaster (Fender Esquire and Fender Broadcaster) were introduced to the musical market and solid-body electric guitars became a public craze. In reaction to market demand, Gibson Guitar president Ted McCarty brought guitarist Les Paul into the company as a consultant. Les Paul was a respected innovator who had been experimenting with guitar design for years. He hand-built a solid-body prototype called "The Log", often suggested as the first solid-body Spanish guitar ever built. "The Log" was given its name from the pine block running through the middle of the guitar whose width and depth are a little more than the width of the fretboard; conventional hollow guitar sides or "wings" were added for shape. Although numerous other prototypes and limited-production solid-body models by other makers have since surfaced, it is known that in 1945–1946, Les Paul had approached Gibson with "The Log" prototype, but his solid body design was rejected.[7][8]

In 1951, Paul, McCarty, and his team at the Gibson Guitar Corporation began work on what would eventually become the Les Paul Model. Early prototypes are very similar to the final version.[9] The new Les Paul guitar was to be an expensive, well-made instrument in accordance with Gibson's reputation at the time.[7] Although recollections differ regarding who contributed what to the Les Paul design, it was far from a replica of rival guitar manufacturer Fender's models.

Les Paul logo on headstock

Additionally, Gibson's president Ted McCarty stated that the Gibson Guitar Corporation approached Les Paul for the right to imprint the musician's name on the headstock with the intention of increasing sales; in 1951, Gibson presented Paul a nearly finished instrument for approval. Subsequently, McCarty claimed that design discussions with Les Paul were limited to the tailpiece and the fitting of a maple cap over the mahogany body for increased density and sustain, which Les Paul had requested reversed. However, this reversal would have caused the guitar to become too heavy, and Paul's request was refused.[10] Paul states that the original Custom should have had the maple cap and the Goldtop was to be all mahogany. The Custom did not appear on the market for another two years following the introduction of the Goldtop; it is possible that Gibson had planned a full model range of guitars (with a roll-out over the course of several years) at the time when initial specifications were being set. Les Paul's contributions to the guitar line bearing his name were more than cosmetic, but certainly included them. For example, Paul specified that the guitar be offered in a gold finish, not only for flashiness, but to emphasize the high quality of the Gibson Les Paul instrument.[10] The later-issue Les Paul models included flame maple (tiger stripe) and "quilted" maple tops, again in contrast to the competing Fender line's range of car-like custom color finishes.

The 1952 Les Pauls featured two P-90 single coil pickups, and a one-piece, 'trapeze'-style bridge/tailpiece with strings fitted under (instead of over) a steel stop-bar.[note 4]

The guitar made its public debut when Paul used it onstage in June, 1952, at the Paramount theatre in New York. On July 24, 1952, at a special musicians clinic at the Waldorf-Astoria hotel, it was previewed by prominent guitarists such as Tiger Haynes, George Barnes, Mundell Lowe, Tony Mottola, and Billy Mure.[11] The clinic preceded the annual NAMM Show held at the New Yorker hotel starting July 27, where the guitar was first received by the general public at Gibson's exhibit in rooms 611 through 615.[11]

"Patent Applied For" (PAF) pickups on a Les Paul Standard Tune-o-matic bridge with stopbar tailpiece

A second Les Paul model was introduced in 1953. Called the Les Paul Custom, this black guitar with gold-plated hardware was dubbed the "Black Beauty". Various bridge and tailpiece designs were added in 1953 and 1954, including the popular Tune-o-matic bridge. The Goldtop and Custom models continued without significant changes until 1957. In 1957, P-90 pickups were no longer offered on Les Pauls. New humbucker pickups designed by Seth Lover in 1955 (U.S. Patent 2,896,491) debuted on Les Pauls in 1957. This innovation in pickups became the flagship pickup design most associated with Gibson. Many other guitar companies followed suit, outfitting their electrics with versions of the humbucking pickup.

1959 Les Paul Standard Reissue Peter Green (1970) Jeff Beck (1968)

In 1958, the Les Paul saw its first major design change. A new model, called the Standard, retained most features of the 1957 Goldtop. However, Standards featured a cherry-red sunburst finish. These guitars were priced higher than the Goldtop models, but lower than the Customs. At this time, Gibson instruments were marketed toward an older, jazz-oriented audience rather than young burgeoning guitarists. As a result, over the three-year period of production, only c. 1,700 Standards were made.

These Les Pauls were considered to be too heavy and old-fashioned, and they initially did not find favor amongst guitarists. In 1961, Gibson stopped producing the traditional Les Paul in favor of a lighter redesign which was later called the SG. The mid-1960s, however, brought a resurgence of interest in the Les Paul Standard. In 1964, The Rolling Stones' Keith Richards began using a sunburst, 1959 Les Paul Standard – becoming the first "star-guitarist" to play a Les Paul on the British scene.[12][13] The guitar, outfitted with a Bigsby tailpiece, served as one of the guitarist's prominent instruments and provided the first impetus to the use of Les Pauls during the British blues boom.[14][15] In 1965, Eric Clapton began using Les Pauls because of the influence of Freddie King and Hubert Sumlin, and played a 1960 Standard on the groundbreaking album Blues Breakers with Eric Clapton.[16][17][18] In America, Mike Bloomfield began using a 1954 Les Paul goldtop while touring with the Paul Butterfield Blues Band, and recorded most of his work on the band's East-West album with that guitar. A year later, he traded it for a 1959 Standard with which he became most identified. By 1967, Jerry Garcia of the Grateful Dead was using mid-1950's, P-90 pickup-equipped goldtops or black custom models, which he used through 1968.[19] Concurrently, artists such as Peter Green, Jeff Beck, Paul Kossoff, and Jimmy Page began using sunburst Les Paul Standards in the late 1960s. Responding to this influence and increased pressure from the public, Gibson reintroduced Les' single-cutaway guitar in July 1968, and the guitar remains in production today.

1969 Standard (refinished) 1974 Custom Sunburst

In 1969, Gibson's parent company (Chicago Musical Instruments) was taken over by the conglomerate ECL.[20][21] Gibson remained under the control of CMI until 1974 when it became a subsidiary of Norlin Musical Instruments.

The pancake-like layers, seen on the edge of cross-banding, multi-piece body in Norlin Era

These ownership changes, often called the "Norlin Era", caused Gibson products of the time to decline in quality. Les Paul designs were altered and a reinforced upper neck volute to decrease headstock breaks was added. Neck woods were changed from one-piece mahogany to a three-piece maple design. The body was also changed from one-piece mahogany with a maple top to multiple slabs of mahogany with multiple pieced maple tops. This is referred to as "multipiece" construction, and sometimes incorrectly referred to as a "pancake" body. The expression "pancake body" actually refers to a body made of a thin layer of maple sandwiched between two slabs of mahogany, with a maple cap. The grain of the maple was placed at 90 degrees to that of the mahogany. The "pancake"-like layers are clearly visible when looking at the edge of the guitar. This process is also known as "crossbanding", and was done to make use of less expensive and more readily available thinner mahogany. Crossbanding was phased out by 1977.

In this era, Gibson began experimenting with new models, such as the Les Paul Recording. This guitar was generally unpopular with guitarists because of its complex electronics. Less noticeable changes included, but were not limited to, optional maple fingerboards (added in 1976), pickup cavity shielding, and the crossover of the ABR1 Tune-o-matic bridge into the wide "Nashville" bridge. During the 1970s, the Les Paul body shape was incorporated into other Gibson models, including the S-1, the Sonex, the L6-S, and other models that did not follow the classic Les Paul layout.

Gibson Les Paul Custom Florentine

In January 1986, Gibson again changed ownership and began manufacturing a range of varied Les Paul models. The 1980s also saw the end to several design characteristics, including the volute and maple neck. However, because of consumer demand, the Gibson Les Paul guitar is available today in a wide array of choices, ranging from guitars equipped with modern digital electronics to classic re-issue models built to match the look and specifications of the guitar's earliest production runs from 1952 to 1960.

In 1986, to respond to the high demand for vintage models, Gibson formed a "Custom Shop" division. Originally, the Shop began producing accurate reproductions of early Les Pauls as well as one-off orders.[22] Today, the Custom Shop produces numerous limited-run "historic-spec" models, as well as signature artist models. The first Custom Shop artist guitar was the 1996 Joe Perry Les Paul.

The post-1954 Les Paul guitar line included two models: the Standard (nicknamed the Goldtop), and the Custom (which offered gold hardware and a more formal black finish). However, advancements in pickup, body, and hardware designs allowed the Les Paul to become a long-term series of electric solid-body guitars that targeted multiple price-points and market levels.

1952–53 Goldtop with trapeze bridge[note 5] 1953–55 Goldtop with stopbar bridge 1955–57 Goldtop with Tune-o-matic bridge and stopbar tailpiece 1957–58 Goldtop with PAF pickups

Goldtops, the first Les Paul model, were produced from 1952–1957. Early 1952 Les Pauls were not issued serial numbers, did not have bound fingerboards, and are considered by some as "LP Model prototypes". However, later 1952 Les Pauls were issued serial numbers and also came with bound fingerboards. Interestingly, the design scheme of some of these early models varied. For instance, some early Les Pauls were fitted with black covered P90 pickups instead of the cream-colored plastic covers that are associated with this guitar. The weight and the tonal characteristics of the Goldtop Les Paul were largely due to the mahogany and maple construction.

In 1953, the trapeze tailpiece was dropped, and a new stopbar design was added. This design combined a pre-intonated bridge and tailpiece with two studs just behind the bridge pickup. This increased the sustain of the Goldtop noticeably; however, the intonation and string height adjustability were limited. A new design, the Tune-o-matic, replaced the stopbar in 1955. It consisted of a separate bridge and tailpiece attached directly to the top of the guitar, combining an easily adjustable bridge with a sustain-carrying tailpiece. This design has been used on most Les Pauls ever since. The tuners were produced by Kluson.

1954 Custom with P90 pickups. 1960 Custom reissue with PAF pickups. Main article: Gibson Les Paul Custom

The Les Paul Custom features gold hardware, multilayer binding including the headstock, ebony fingerboard, real mother-of-pearl inlays and two or three-pickup layout. 1950s Customs were all-mahogany, rather than the mahogany-with-maple-cap of the Goldtop. The original Customs were fitted with a P-90 pickup in the bridge position and an Alnico V "staple" pickup in the neck. In 1957, the Custom was fitted with Gibson's new PAF humbucker pickups,[23] and later became available with three pickups instead of the usual two. The traditional Les Paul Custom was discontinued in 1961 and its name transferred to the custom version of the then-new Gibson SG.

In 1968, Gibson reintroduced the Les Paul Custom as a two-pickup-only model. The headstock angle was changed from 17 degrees to 14, and a wider headstock and a maple top (in lieu of the original 1953-1961 mahogany top construction) were added. White and two sunburst finish options were added to the color palette in 1974. Also new in 1974 was the optional TP-6 fine-tuner tailpiece, allowing for micro-adjustment of string tuning from the bridge. The mahogany neck was replaced with a three-piece maple neck in 1975 (though mahogany still saw limited use) with this change lasting till around 1982. Popular colors, such as wine red and "silverburst," were added in the 1970s and '80s. Gibson currently produces several Custom models with various finishes and pickups.

In 1958, new Standard model retained most specifications of the 1957 Goldtop, including PAF humbucker pickups, a maple top, and a tune-o-matic bridge with a stop tailpiece or Bigsby vibrato tailpiece. The gold color used since 1952 was replaced by a cherry-red version of the Sunburst finish long used on Gibson's flat-top and archtop acoustic and hollow electric guitars. Since the maple cap was now visible, tops were made either with a solid "plaintop" piece of maple or two bookmatched pieces of figured (curly or quilted) maple. To differentiate from the earlier Goldtop model, the new Les Paul was referred to as The Les Paul Standard. Specifications during 1958–60 varied from year to year and also from guitar to guitar. Typical 1958 Les Paul Standard necks had a thicker neck, thinner frets and lower fret height, which changed during the course of 1959 to develop into typical 1960 necks with a thinner cross-section and wider, higher frets.[note 6][note 7] The cherry dye used on the 1958–59 models faded rapidly from ultraviolet light exposure, so in early 1960 Gibson switched to a new, fade-resistant formulation which was also less translucent and slightly more orange; this is sometimes called the "tomato soup burst." Original production of the Standards lasted from 1958 to early 1961. Only about 1,700 of these early models were made and have subsequently become highly valuable.[note 7]

Production ended when, in 1961, Gibson redesigned the Les Paul to feature a "double cutaway" body, which has subsequently become the Gibson SG. Because of high demand, Gibson resumed production of Les Paul Standards in 1968.

Main article: Gibson Les Paul Junior 1958 Junior 1959 TV reissue
(Junior DC in TV Yellow)

In 1954, the Les Paul Junior debuted, targeted the beginning or student guitarist. The Junior is characterized by its flat-top "slab" mahogany body, finished in sunburst. It had a single P-90 pickup, simple volume and tone controls, an unbound rosewood fingerboard with plain dot-shape position markers, and a combination bridge/tailpiece unit similar to the Goldtop.

In 1955, Gibson launched the Les Paul TV model, which was identical to the Junior except for the name and a fashionable contemporary "limed oak" style finish, later more accurately named "limed mahogany". This natural wood finish with white grain filler often aged into a natural wood or dull yellow appearance, and eventually evolved into the opaque mustard yellow, popularly called "TV yellow". The model was not, as a popular myth says, to avoid glare from old TV cameras, but a modern look and a name to promote "The Les Paul & Mary Ford Show" then on television.

Gibson made a radical design change to their Junior and TV models in 1958: to accommodate player requests for more access to the top frets than the previous designs allowed, these electric guitar models were revamped with a new double-cutaway body shape. In addition, Juniors were now available with a cherry red finish, while the re-shaped TV adopted a more yellow-tinged finish.

The Les Paul Special was released in 1955, featuring a slab body, two soapbar P-90 single coil pickups, and was finished in a color similar to TV Yellow (but not called a TV model).

In 1959, the Special was given the same new double-cutaway body shape as the Junior and the TV received in 1958. Around this time, Les Paul decided to discontinue his affiliation with Gibson; the model was renamed "SG Special" in late 1959.[24] However, when the new design was applied to the two-pickup Special, the cavity for the neck pickup overlapped the neck-to-body joint. This weakened the joint to the point that the neck could break after only moderate handling. The problem was soon resolved when Gibson designers moved the neck pickup farther down the body, producing a stronger joint and eliminating the breakage problem.

It included such high end items as the Grover tuning keys and the Tune-O-Matic bridge. Affectionately called by some, "The Coffee Table Burst"  because of its natural finish.

Main article: Gibson SG 1962 Les Paul Standard (SG Standard)

In 1960, Gibson experienced a decline in electric guitar sales due to strong competition from Fender's comparable but much lighter double-cutaway design, the Stratocaster. In response, Gibson modified the Les Paul line. For 1961, the Les Paul was thinner and much lighter than earlier models, with two sharply pointed cutaways and a vibrato system. However, the redesign was done without Les Paul's knowledge, and he hated the design, so he asked Gibson to remove his name.[25] The single cutaway designed retained the "Les Paul" name until 1963 when Les Paul's endorsement deal with Gibson ended. Without a contract, Gibson could no longer call its guitars "Les Pauls', and it renamed them "SGs" (for "Solid Guitars").[26]

1972 Deluxe  with mini-humbuckers 1969 Deluxe

The Deluxe was among the "new" 1968 Les Pauls. This model featured "mini-humbuckers", also known as "New York" humbuckers, and did not initially prove popular. The mini-humbucker pickup fit into the pre-carved P-90 pickup cavity using an adaptor ring developed by Gibson in order to use a surplus supply of Epiphone mini-humbuckers. The Deluxe was introduced in late 1968 and helped to standardize production among Gibson's U.S.-built Les Pauls. The first incarnation of the Deluxe featured a one-piece body and slim three-piece neck. The multipiece body (a thin layer of maple on top of two layers of Honduran mahogany) arrived in 1969. In late 1969, a reinforcing neck volute was added. 1969 Deluxes feature the Gibson logo devoid of the dot over the "i" in Gibson. By late 1969/early 1970, the dot over the "i" had returned, plus a "Made In USA" stamp on the back of the headstock. The Deluxe could be specially-ordered with full-size humbucker pickups; such full size versions of the Deluxe were "Standard" spec. By 1975, the neck construction was changed from mahogany to maple, until the early 1980s, when the construction was returned to mahogany. The body changed back to solid mahogany from the pancake design in late 1976 or early 1977. Interest in this particular Les Paul model was so low that in 1985, Gibson canceled it. In 2005, the Deluxe was re-introduced.[citation needed]

In 1978, the Les Paul Pro Deluxe was introduced. This guitar featured P-90 pickups (like the original 1952-1956 LPs) instead of the "mini-humbuckers" of the Deluxe model, an ebony fingerboard, maple neck, mahogany body and chrome hardware. It came in ebony, cherry sunburst, tobacco sunburst or gold finish. It was discontinued in 1983.

The Gibson Dark Fire, a variant of the Gibson Les Paul, was an electric solid body guitar produced by Gibson Guitar Corporation. It was a second generation Robot Guitar, using an updated version of the Powertune self-tuning system produced by Tronical Gmbh. The Dark Fire also introduced Gibson's Chameleon Tone Technology, a system consisting of onboard electronics designed to simulate various guitar tones. Additionally, the guitar included an audio interface called the Robot Interface Pack or RIP.

The Dark Fire had one Burstbucker 3 humbucker in the bridge position, a P-90H at the neck, and a special Tronical-designed piezoelectric tune-o-matic sat in the place of the bridge. The Burstbucker 3 and P-90H were selected via the three-way selector switch. The piezoelectric could be activated via the MCK, blending the magnetic and piezoelectric together under a standard 1/4" guitar cable. Gibson supplied a TRS stereo cable that allowed the piezo signal and the magnetic signal to be split between two different amps.

The Studio model was introduced in 1983, and is still in production. The guitar is intended for the studio musician; therefore, the design features of the "Les Paul Studio" are centered on optimal sound output and not on flashy appearance. This model retains only the elements of the Gibson Les Paul that contribute to tone and playability, including the carved maple top and standard mechanical and electronic hardware. However, the Studio design omits several stock Gibson ornamentations that do not affect sound quality, including body/neck binding. The first Studios from 1983 to 1986 were made with alder bodies rather than mahogany/maple. The current Studios come with a chambered mahogany body with either a maple or mahogany cap. The entry level Les Paul Studio "faded" has a weight relieved mahogany body and top and a satin finish.

Gibson also offered the Studio in a "standard" model. This variant was adorned with neck and body binding, ebony fretboard and sunburst paint job. All Studios at the time had dot fretboard markers and a thinner body.

Gibson released the ES-Les Paul in 2015. It is a semi-acoustic model with f-holes and two Alnico humbuckers. The neck is mahogany, but the sides and back are laminated maple and poplar. A mahogany block runs throughout the body to increase sustain.[27]

Les Paul playing his customized Les Paul Recording guitar

Until his death in August 2009, Les Paul himself played his personal Les Paul Guitar onstage weekly in New York City. Paul preferred his 1971 Gibson "Recording" model guitar, with different electronics and a one-piece mahogany body, and which, as an inveterate tinkerer and inventor, he had modified heavily to his liking over the years. A Bigsby-style vibrato was of late the most visible change although his guitars were formerly fitted with his "Les Paulverizer" effects.

Main article: Epiphone Les Paul Les Paul Special II Les Paul Ultra II

The Gibson-owned Epiphone Company makes around 20 models of the Les Paul, most are similar copies of Gibson-made models. Made in places outside the U.S., the Epiphone Les Pauls are made from more commonly available woods using less expensive foreign labor and have less hand detailing than the Gibson models, and, as a result, sell for a lower price. Epiphone Guitar Co. has been owned by Gibson Guitars since the 1950s.[28]

Epiphone also makes several less common models of the Les Paul such as the Les Paul Goth, Les Paul Ultra/Ultra II, Les Paul Prophecy, and Les Paul Tribute Plus.[29][30]

Jimmy Page with a Goldtop Classic Premium, one of his many Les Pauls Main article: Jimmy Page § Signature models

Gibson has produced three Jimmy Page signature models. The first was issued in the mid-1990s. It is based on a stock sunburst Les Paul Standard. In 2005 the Gibson Custom Shop issued a limited run of Jimmy Page Signature guitars based on Jimmy Page's 1959 "No. 1". Several years later, Gibson issued its third Jimmy Page Signature guitar, this one based on Jimmy Page's #2, issued in a production run of 325 guitars.

Slash with one of his signatures in 2007

Slash has collaborated with Gibson on eight signature Les Paul models.

The first of these guitars is the Slash "Snakepit" Les Paul Standard, which was introduced by the Gibson Custom Shop in 1996, based on the smoking snake graphic off the cover of Slash's Snakepit's debut album and a mother of pearl snake inlay covering the length of the ebony fretboard. Production was limited to 100.[31]

Gibson Slash "Appetite" Les Paul

In 2004, the Gibson Custom Shop introduced the Slash Signature Les Paul Standard, a guitar that Gibson has used ever since as the "standard" non-limited edition Slash Les Paul.[32] In 2008, Gibson USA released the Slash Signature Les Paul Standard, an authentic replica of one of two Les Pauls Slash received from Gibson in 1988. It has an Antique Vintage Sunburst finish over a solid mahogany body with a maple top.[33] Also in 2008, the Gibson Custom Shop introduced the Slash "Inspired By" Les Paul Standard. This guitar is a replica of his 1987 Les Paul Standard.[31][34]

In 2010, Gibson released the Slash "Appetite" Les Paul Standard as a tribute to Guns N' Roses' debut album, Appetite for Destruction, which resembles the Kris Derrig built 1959 Les Paul replica Slash used for the recording of the album.[35] Production was limited to 400, with 100 aged guitars signed by Slash, and another 300 finished with the Custom Shop's VOS process.[36]

Joe Perry playing his signature "Boneyard" Les Paul

Gibson has issued two signature Les Paul guitars for Joe Perry of Aerosmith. The first was developed in 1996 and was customized with an active mid-boost control, black chrome hardware, and a translucent black finish. It was replaced in 2004 by a second, more visually distinctive Les Paul, the "Boneyard" Les Paul. This guitar is characterized by Perry's custom "Boneyard" logo on the headstock and a figured maple top with a green tiger finish, and is available with either a stopbar tailpiece or a Bigsby tailpiece.

Gary Moore Les Paul

Gary Moore created his own signature Les Paul in the early 2000s, characterised by a yellow flame top, no binding and signature truss rod cover. It featured two open-topped humbucker pickups, one with "zebra coils" (one white and one black bobbin). In 2009, Gibson released another Gary Moore signature guitar, the Gibson Gary Moore BFG Les Paul. The Gary Moore BFG is much like their previous Les Paul BFG series, with the added styling of Moore's various 1950s Les Paul Standards.

Peter Frampton '54 Custom

A replica of the three-pickup "Black Beauty" Les Paul Custom used by Peter Frampton as his main guitar from his days in Humble Pie through his early solo career was introduced through the Gibson Custom Shop in 2012. Frampton's original guitar was a 1954 Les Paul modified extensively. His famous guitar was presumed lost in a South American plane crash in 1980, but was returned to Frampton in 2011.

Gibson used hundreds of photographs of the late blues guitarist's instrument to produce the limited-edition Bloomfield signature. The company produced one hundred Bloomfield models with custom-aged finishes and two hundred more with the company's VOS finishing in 2009. They reproduced the tailpiece crack on the aged version, plus the mismatched volume and tone control knobs and the "Les Paul"-engraved truss rod cover on both versions, while including a toggle switch cover. The headstock was characterized by the kidney-shaped Grover tuning keys installed on the guitar before Bloomfield traded for it.

Roger Daltrey & Pete Townshend with his modified Les Paul Deluxe

In 2005, Gibson issued three Pete Townshend signature edition Les Paul Deluxe guitars, based on Townshend's heavily customised "#1" Wine Red 1976 Les Paul Deluxe, "#3" Gold top 1976, and "#9" Cherry Sunburst 1976. These guitars were modified by Alan Rogan and used extensively on stage and in the studio with The Who. In addition to the two mini-humbuckers the guitar carried, Rogan modified Townshend's originals with a DiMarzio humbucker in the middle. Toggle switches located behind the guitar's tailpiece turned the pickup on and off and added volume boost. The control knobs were wired for volume, one for each pickup and a master volume. The reissues differed from Townshend's originals in that the reissues had an inlay at the first fret while the originals did not.

Ace Frehley
with his 3-pickup Les Paul Custom Billy Gibbons
with a Les Paul Goldtop

The Ace Frehley (KISS) signature model (released in 1997 and re-released in 2012) has three double-white DiMarzio pickups, a cherry sunburst finish (AAAA), a color image of Frehley's face in his Kiss make-up on the headstock, mother-of-pearl lightning bolt inlays, and Ace's simulated signature on the 12th fret. A Custom Shop run of only 300 guitars were built with DiMarzio PAF, Super Distortion, and Dual Sound pickups. The production run model was only built with DiMarzio Super Distortion pickups. This was one of Gibson's best selling artist runs. The more recent 2012 "Budokan" model, intended to pay tribute to the guitar used during the KISS' first trip to Japan in 1977, features mother-of-pearl block inlays (no signature at the 12th fret), Grover machine heads with pearloid banjo buttons, and a grade A maple top.[37]

Billy Gibbons of ZZ Top has a signature model and pick-up based on his famous "Pearly Gates" 1959 Les Paul Standard.

Eric Clapton playing a Les Paul in 1987, on the right of George Harrison

Clapton played a 1960 Standard as a member of John Mayall and the Bluesbreakers as well as in the early days of Cream. The guitar was said to have been stolen while Clapton was preparing for the first Cream tour in 1966, following the recording of Fresh Cream, and was long considered an iconic instrument by Clapton's fans. Gibson announced production of the Clapton 1960 Standard, also nicknamed the "Beano Burst", in 2010. Gibson says the instrument "accurately represents what Eric Clapton personally feels his 1960 Les Paul should be", with Clapton consulting on the design of the guitar. Production is limited but all feature period-correct hardware, two Gibson reproduction PAF humbucking pickups, and subtly figured "antiquity burst" maple tops.

Paul Kossoff, of Free and Back Street Crawler, favored a 1959 Les Paul Standard. In 2011–12, Gibson's Custom Shop made a reproduction of Kossoff's Standard, featuring a so-called "green-lemon" flametop, two-piece carved maple top, mahogany body and neck, Custom Bucker humbucking pickups and kidney-bean shaped Grover tuners similar to those Kossoff had installed on the instrument. 100 Kossoff models were made to resemble the guitar at the time of Kossoff's death in 1976, with another 250 in a VOS finish.

Although early Les Paul imitations in the 1960s and 1970s, such as those made by Höfner, Hagström, Harmony Company, and Greco differed from Gibson's designs, with different electronics and even bolt-on necks, in the late 1970s some Japanese companies came very close to perfecting copies of the original 1958-1960 Standards.

A lawsuit was brought by the Norlin Corporation (the parent company of Gibson) in 1977, against Elger/Hoshino U.S.A. (manufacturer and distributor, respectively, of Ibanez) over use a headstock shape and logo, both considered similar to the Gibson designs. However, the suit was based on an Ibanez headstock design that had been discontinued by 1976. The case was officially closed on February 2, 1978. Those mid-1970s guitars later became known as "lawsuit era" guitars.

ESP Guitars makes several guitars based on the Les Paul design. The Edwards and Navigator lines are made in Japan in the vein of the late 1970s and 1980s guitars from Tokai, Burny, and Greco, complete with Gibson style headstocks.

Heritage Guitars, founded in 1985 by four long-time Gibson employees when Gibson relocated to Nashville, continues to build guitars at the original factory in Kalamazoo, Michigan. Many of their models are inspired by Gibson's late-1950s/early-1960s sunbursts and Customs.

In 2006, Gibson lost a lawsuit against PRS Guitars,[38] Gibson claiming PRS was infringing on the Les Paul shape and design. The court's decision allowed PRS to reintroduce single cutaway versions of its instruments.

In 2008, Gibson lost the trademark for the Les Paul in Finland. According to the court, "Les Paul" has become a common noun for guitars of a certain type. The lawsuit began when Gibson sued Musamaailma, which produces Tokai guitars, for trademark violation. However, several witnesses testified that the term "Les Paul" denotes character in a guitar rather than a particular guitar model. The court also found it aggravating that Gibson had used Les Paul in the plural form and that the importer of Gibson guitars had used Les Paul as a common noun. The court decision will become effective, as Gibson is not going to appeal.[39]

Mesa-Boogie "Mark IV", a guitar combo amplifier

A guitar amplifier (or guitar amp) is an electronic amplifier that strengthens the weak electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet. A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier (and preamplifier) circuits, requiring the use of a separate speaker cabinet–or it may be a "combo" amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet. There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight "practice amplifiers" with a single 8" speaker to heavy combo amps with four 10" speakers and a powerful amplifier, which are loud enough to use in a nightclub or bar performance.

Guitar amplifiers can also modify the instrument's tone by emphasizing or de-emphasizing certain frequencies, using equalizer controls, which function the same way as the bass and treble knobs on a home hi-fi stereo, and by adding electronic effects; distortion (also called "overdrive") and reverb are commonly available as built-in features. The input of modern guitar amplifiers is a 1/4" jack, which is fed a signal from an electro-magnetic pickup (from an electric guitar) or a piezoelectric pickup (usually from an acoustic guitar) using a patch cord, or a wireless transmitter. For electric guitar players, their choice of guitar amp and the settings they use on the amplifier are a key part of their signature tone or sound. Some guitar players are longtime users of a specific amp brand or model. Many electric guitar players use external effects pedals to alter the sound of their tone before the signal reaches the guitar amp, such as the wah wah pedal and the chorus pedal.

This article focuses on electric guitar amps. For information on amps for bass guitar, a lower-pitched, similar instrument, see the article on bass amps.

Typically, guitar amplifiers have two amplifying circuit stages and in addition frequently have tone-shaping electric circuits, which usually include at least bass and treble controls, which function similarly to the equivalent controls on a home hi-fi system. More expensive amplifiers typically have more controls for other frequency ranges, such as one or two "midrange" controls and a "presence" control for very high frequencies. Some guitar amplifiers have a graphic equalizer, which uses vertical fader controls which can control many frequency bands. The first amplifier stage is a preamplifier stage (there may be more than one), which amplifies the guitar signal to a level that can drive the power stage. The power amplifier or output stage produces a high current signal to drive a loudspeaker to produce sound that the guitarist and audience can hear.

There may be one or more tone stages that affect the character of the guitar signal:

Tone stages may also provide electronic effects—such as equalization, compression, distortion, chorus, or reverb. Amplifiers may use vacuum tubes (called valves in Britain), solid-state (transistor) devices, or both.

There are two configurations of guitar amplifiers: combination ("combo") amplifiers, which include an amplifier and one or more speakers in a wooden cabinet, and the standalone amplifier (often called a "head" or "amp head"), which does not include a speaker, but passes the amplified signal via a speaker cable to one or more external speaker cabinets. A wide range of speaker configurations are available in guitar cabinets, ranging from cabinets with a single speaker (e.g., 1×10" or 1×12") or multiple speakers (e.g., 2×10", 4×10" or 8x10"). Guitar amplifiers have a wide range in price and quality. Music equipment companies import small, low-powered practice amplifiers for students and beginners that sell for less than $50 USD. Other companies produce expensive custom-made amplifiers for professional musicians, which can cost thousands of dollars. Most combo amplifiers have a carrying handle, and many combo amplifiers and cabinets have metal or plastic-reinforced corners to protect the amp during transportation.

Control knobs are typically mounted on the front of the cabinet or chassis, though in some cases, the knobs are on a recessed panel at the back of the top of the amplifier. The most basic amps only have a few knobs, which typically control volume, bass and treble. More expensive amps may have a number of knobs that control pre-amp volume (or "gain"), distortion or overdrive, volume, bass, mid and treble, and reverb. Some older amps (and their re-issued versions) have a knob that controls a vibrato effect. The 1/4" input jack is typically mounted on the front of the amplifier. In the simplest, least expensive amplifiers, this 1/4" jack is the only jack on the amplifier. More expensive amplifiers may have a patch bay for multiple inputs and outputs, such as a pre-amp out (for sending to another guitar amplifier), an in jack to create an effects loop (when used with the pre-amp out jack), an external speaker output (for powering an additional speaker cabinet), and stereo RCA jacks or an 1/8" jack, for connecting a CD player or MP3 player so that a player can practice along with recorded music. Some amps have a 1/4" jack for connecting a pedal to turn the amp's onboard overdrive and reverb on and off or to switch between channels. The vast majority of guitar amps can only be powered by AC mains power (plugging into a wall outlet); however, a small number of practice amps designed for buskers also have battery power, enabling them to be used for street performances.

A 1940s-era Valvo combo amp. Fender Deluxe 1953

In the 1920s, it was very hard for a musician playing a pickup-equipped guitar to find an amplifier and speaker to make their instrument louder as the only speakers that could be bought were "radio horns of limited frequency range and low acoustic output". The cone speaker, widely used in 2000s-era amp cabinets, was not offered for sale until 1925. The first amplifiers and speakers could only be powered with large batteries, which made them heavy and hard to carry around. When engineers developed the first AC mains-powered amplifiers, they were soon used to make musical instruments louder. Engineers invented the first loud, powerful amplifier and speaker systems for public address systems and movie theaters. These large PA systems and movie theatre sound systems were very large and very expensive, and so they could not be used by most touring musicians. After 1927, smaller, portable AC mains-powered PA systems that could be plugged into a regular wall socket "quickly became popular with musicians"; indeed, "...Leon McAuliffe (with Bob Wills) still used a carbon mic and a portable PA as late as 1935." During the late 1920s to mid-1930s, small portable PA systems and guitar combo amplifiers were fairly similar. These early amps had a "single volume control and one or two input jacks, field coil speakers" and thin wooden cabinets; remarkably, these early amps did not have tone controls or even an on-off switch.[1]

In 1928, the Stromberg-Voisinet firm was the first company to sell an electric stringed instrument and amplifier package. However, musicians found that the amps had an "unsatisfactory tone and volume, [and] dependability problems", so the product did not sell well. Even though the Stromberg-Voisinet amp did not sell well, it still launched a new idea: a portable electric instrument amp with a speaker, all in an easily transported wooden cabinet. In 1929, Vega electrics launched a portable banjo amplifier. In 1932, Electro String Instruments and amplifier (this is not the same company asStromberg Electro Instruments) introduced a guitar amp with "high output" and a "string driven magnetic pickup". Electro set out the standard template for combo amps: a wooden cabinet with the electronic amplifier mounted inside, and a convenient carrying handle to facilitate transporting the cabinet. 1n 1933, Vivi-Tone amp set-ups were used for live performances and radio shows. In 1934, Rickenbacker launched a similar combo amp which added the feature of metal corner protectors, which keep the corners in good condition during transportation.[1]

In 1933, Dobro released an electric guitar and amp package. The combo amp had "two 8″ Lansing speakers and a five-tube chassis. Dobro made a two speaker combo amp that was on the market over 12 years before Fender launched its two-speaker "Dual Professional/Super" combo amp. In 1933, Audio-Vox was founded by Paul Tutmarc, the inventor of the first electric bass (Tutmarc's instrument did not achieve market success until Leo Fender's launched the Precision Bass). In 1933, Vega sold a "pickup and amplifier set" which a musician could use with her/his existing guitar. In that same year, the Los Angeles-based Volu-Tone company also sold a pickup/amplifier set. Volu-Tone used "high voltage current" to sense the string vibration, a potentially dangerous approach that did not become popular. In 1934 Dobro released a guitar amp with a vacuum tube rectifier and two power tubes. By 1935, Dobro and National began selling combo amps for Hawaiian guitar. In 1934, Gibson developed prototype combo amps, but these never got produced and sold. By 1935, Electro/Rickenbacher sold "more amps and electric guitars than all the amps and electrified/electric guitars made from ’[19]28 through the end of ’[19]34, combined."[1]

The first electric instrument amplifiers were not designed for use with electric guitars. The earliest examples were portable PA systems, which appeared in the early 1930s when the introduction of electrolytic capacitors and rectifier tubes allowed the production of economical built-in power supplies that could be plugged into wall sockets, instead of heavy multiple battery packs, since rechargeable batteries would not become lightweight until many decades later. While guitar amplifiers from the beginning were used to amplify acoustic guitar, electronic amplification of guitar was first widely popularized by the 1930s and 1940s craze for Hawaiian music, which extensively employed the amplified lap steel Hawaiian guitar.[2]

In the 1920s, the earliest combo amplifiers did not have any tone controls. Tone controls on early guitar amplifiers were very simple and provided a great deal of treble boost, but the limited controls, the loudspeakers used, and the low power of the amplifiers (typically 15 watts or less prior to the mid-1950s) gave poor high treble and bass output. Some models also provided effects such as an electronic tremolo unit. Early Fender amps labeled tremolo as "vibrato" and labeled the vibrato arm of the Stratocaster guitar as a "tremolo bar" (see vibrato unit, electric guitar, and tremolo). Some later models included an onboard spring reverb effect, one of the first being the Ampeg Reverberocket amp.

In the 1950s, several guitarists experimented with distortion produced by deliberately overdriving their amplifiers, including Goree Carter,[3]Joe Hill Louis,[4][5]Elmore James,[6]Ike Turner,[7]Willie Johnson,[8]Pat Hare,[9]Guitar Slim,[10]Chuck Berry,[11]Johnny Burnette,[8] and Link Wray.[12] In the early 1960s, surf rock guitarist Dick Dale worked closely with Fender to produce custom made amplifiers,[13] including the first 100-watt guitar amplifier.[14] He pushed the limits of electric amplification technology, helping to develop new equipment that was capable of producing "thick, clearly defined tones" at "previously undreamed-of volumes."[13]

U2 guitarist The Edge's 1964 Vox AC30 combo amp.

Distortion became more popular from the mid-1960s, when The Kinks guitarist Dave Davies produced distortion effects by connecting the already distorted output of one amplifier into the input of another. Later, most guitar amps were provided with preamplifier distortion controls, and "fuzz boxes" and other effects units were engineered to safely and reliably produce these sounds. In the 2000s, overdrive and distortion has become an integral part of many styles of electric guitar playing, ranging from blues rock to heavy metal and hardcore punk.

Guitar combo amplifiers were at first used with bass guitars and electric pianos, but these instruments produce a wider frequency range and need a full-range speaker system. Much more amplifier power is required to reproduce low-frequency sound, especially at high volume. Reproducing low frequencies also requires a suitable woofer or subwoofer speaker and enclosure. Woofer enclosures must be larger and more sturdily built than cabinets for mid-range or high-frequency (tweeter) speakers. As such, in the 1950s, when Ampeg introduced bass amplifier and speaker systems, these began to be used by bass guitarists. Similarly, Hammond organ players used a specialized keyboard combo amplifier, the Leslie speaker cabinet, which contains a woofer for the low frequencies and a horn for the high frequencies. The Leslie horns rotated and a baffle around the woofer rotated as well, producing a chorus effect.

Guitar amplifiers are manufactured in two main forms: a "combo" contains the amplifier and one or more speaker(s) in a single wooden speaker enclosure. A separate configuration is available as well, with a separate amplifier (the "head") on top of one or more cabinets, each of which contains one or more speakers. Another alternative device used for guitar are public address amplifiers. Grunge guitarist Kurt Cobain used four 800 watt PA amplifiers for his early guitar set-up.

Besides one or more instrument inputs (typically a 1/4" jack), other jacks may also be provided, such as an auxiliary input jack (sometimes with its own level control, for a drum machine), "send" and "return" jacks to create an effects loop, an extension speaker jack. Practice amps may have stereo RCA or mini jacks for connecting a CD player, portable media player or other sound source and a 1/4" headphone jack. Some guitar amps have an XLR input so that a microphone can be plugged in for singing. Guitar amps that include a mic input are in effect small, portable PA systems.

A wide range of instrument amplifiers is available at a wide range of price, quality, and performance levels. Some amplifiers are designed for beginners, such as small, low-wattage "practice amplifiers", which typically have a single 8" speaker and about 10 watts, or smaller "combo" amps with relatively low wattage (15 to 20 watts) and a single 10" speaker. Mid- to large-size "combo" amps with 30 to 50 watts and one 12" speaker or four 10" speakers are designed for use in band rehearsals and onstage performances. Some guitar amps are designed for specific instruments or particular genres, such as the Marshall amps, which are widely used in heavy metal music.

Vacuum tubes (called "valves" in British English) were by far the dominant active electronic components in most instrument amplifier applications until the 1970s, when solid-state semiconductors (transistors) started taking over. Transistor amplifiers are less expensive to build and maintain, reduce the weight and heat of an amplifier, and tend to be more reliable and more shock-resistant. Tubes are fragile and they need to be replaced and maintained periodically. As well, serious problems with the tubes can render an amplifier inoperable until the issue is resolved. In the 2000s, high-end tube instrument amplifiers (along with a small number of hi-fi power amplifiers used by audiophiles and high-end studio microphone preamplifiers) survive as the few exceptions, because of their perceived sound quality. Tube enthusiasts believe that tube amps produce a "warmer" sound and a more natural "overdrive" sound. Typically, tube amps use one or more dual triodes in the preamplifier section to provide sufficient voltage gain to offset tone control losses and drive the power amplifier section. While tube technology is, in many ways, outdated, tube amps remain popular since many guitarists prefer their sound.[15]

Since the 1980s, most inexpensive and mid-priced guitar amplifiers are based on semiconductor (solid-state) circuits. Some designs incorporate tubes in the preamp stage for their subjectively warmer overdrive sound—see "Hybrid amplifiers", below. Solid-state amplifiers are much cheaper to produce and more reliable, and they are usually much lighter than tube amplifiers.[15] High-end solid-state amplifiers are less common, since many professional guitarists tend to favor vacuum tubes. Some jazz guitarists, however, tend to favor the "cleaner" sound of solid-state amplifiers; only a few solid-state amps have enduring attraction, such as the Roland Jazz Chorus.[15][16][17] Solid-state amplifiers vary in output power, functionality, size, price, and sound quality in a wide range, from practice amplifiers to combos suitable for gigging to professional models intended for session musicians who do studio recording work.

A hybrid amplifier involves one of two combinations of tube and solid-state amplification. It may have a tube power amp fed by a solid-state pre-amp circuit, as in most of the original MusicMan Amps, later amplifier models from Alamo Electronics, the Fender Super Champ XD, and the Roland Bolt amplifier. Randall Amplifiers V2 and T2 use hybrid amp technology. Alternatively, a tube pre-amp can feed a solid-state output stage, as in models from Kustom, Hartke, SWR and Vox. This approach dispenses with the need for an output transformer and easily achieves modern power levels.[15]

A modeling amplifier, shown from above. Note the various amplifier and speaker emulations selectable via the rotary knob on the left.

Microprocessor technology allows the use of digital onboard effects in guitar amps to create numerous different sounds and tones that simulate the sound of a range of tube amplifiers and different sized speaker cabinets, all using the same amplifier and speaker. These are known as modeling amplifiers, and can be programmed with simulated characteristic tones of different existing amplifier models (and speaker cabinets—even microphone type or placement), or dialed in to the user's taste. Many amps of this type are also programmable by way of USB connection to a home computer or laptop.[15]Line 6 is generally credited with bringing modeling amplification to the market.[18][19] Modeling amplifiers and stompbox pedals, rackmount units and software programs which provide amplifier, speaker cabinet and mic modeling can give a guitarist with the single modeling amp or unit access to a large number of sounds and tones, such as the simulated sound of tube amplifiers, vintage combo amplifiers, huge 8x10" stacks, without having to bring all of this heavy equipment to the studio or stage.

The use of "Full Range Flat Response" (FRFR) amplification systems by electric guitarists has received an extra impetus from modeling amplifiers. Before the widespread availability of modeling amplifiers and units, an electric guitarist would not be able to plug her/his electric guitar straight into a PA system or powered speaker, because in most rock genres, the tonal coloration that a regular guitar amp's preamplifier, equalization filters, power amp, guitar speaker and cabinet design (e.g., 8x10" cabinet) are an essential part of a guitarist's unique tone. The basic concept of FRFR is that the tone is shaped by sound processors placed in the signal chain before the amplifier/speaker stage. However, instead of a guitar amplifier, with its particular sound-shaping characteristics (e.g., many amps roll off high treble frequencies and many amplifiers add frequency coloration), a flat-frequency response amplification systems can be used, such as amplified speakers or a PA system (full-range speakers),[20] or dedicated combo-style amplifiers with a broad frequency range.[21] Such processors can be traditional guitar effects, a modeling amplifier (without power amplifier), or a computer running tone-shaping software.[20] With an amp modeling pedal or unit, a guitarist could even use a flat-response keyboard amplifier combo amp to produce overdriven, vintage tones and sounds.

These amplifiers are intended for acoustic guitars, especially for the way these instruments are used in relatively quiet genres such as folk and bluegrass. They are similar in many ways to keyboard amplifiers, in that they have a relatively flat frequency response, and are usually designed so that neither power amplifier nor speakers add coloration. To produce this relatively "clean" sound, these amplifiers often have very powerful amplifiers (providing up to 800 watts RMS), to provide additional "Headroom" and prevent unwanted distortion. Since an 800 watt amplifier built with standard Class AB technology would be very heavy, some acoustic amplifier manufacturers use lightweight Class D amplifiers, which are also called "switching amplifiers."

Acoustic amplifiers are designed to produce a "clean", transparent, "acoustic" sound when used with acoustic instruments with built-in transducer pickups and/or microphones. The amplifiers often come with a simple mixer, so that the signals from a pickup and condenser microphone can be blended. Since the early 2000s, it has become increasingly common for acoustic amplifiers to provide a range of digital effects, such as reverb and compression. As well, these amplifiers often contain feedback-suppressing devices, such as notch filters or parametric equalizers.[22]

Metal guitarist Klaus Eichstadt in front of his Marshall stack. A 3×6 stack of mock Marshall guitar cabinets for Jeff Hanneman of Slayer

An amplifier stack consists of an amplifier head atop a speaker cabinet—a head on top of one cabinet is commonly called a half stack, a head atop two cabinets a full stack. The cabinet that the head sits on often has an angled top in front, while the lower cabinet of a full stack has a straight front. The first version of the Marshall stack was an amp head on an 8×12 cabinet, meaning a single speaker cabinet containing eight 12" guitar speakers. After six of these cabinets were made, the cabinet arrangement was changed to an amp head on two 4×12 cabinets, meaning four 12" speakers, to enable the cabinets to be more transportable. Some touring metal and rock bands have used a large array of guitar speaker cabinets for their impressive appearance. Some of these arrangements include only the fronts of speaker cabinets mounted on a large frame.[23]

There are many varieties of speaker combinations used in guitar speaker cabinets, including one 12" speaker, one 15" speaker (this is more common for bass amplifiers than for electric guitar cabinets), two 10" speakers, four 10" speakers, four 12" speakers, or eight 10" speakers. Less commonly, guitar cabinets may contain different sizes of speaker in the same cabinet. Cabinets with eight 10" speakers are large and heavy, and they are often equipped with wheels and a "towel bar"-style handle for transport. Some cabinets use mixed speaker types, such as one 15" speaker and two 10" speakers.

Combo guitar amplifier cabinets and guitar speaker cabinets use several different designs, including the "open back" cabinet, the closed back cabinet (a sealed box), and, less commonly, bass reflex designs which use a closed back along with a vent or port cut into the cabinet.[24] With guitar amps, most "open back" amp cabinets are not fully open; in fact, part of the back is enclosed with panels. Combo guitar amp cabinets and standalone speaker cabinets are often made of plywood; "[d]ecent...cabs have even been constructed from MDF and particle board—although these are typically considered low-budget options."[24] In a cabinet, "...the size and depth of the cabinet, the type of wood used to build it, the way that wood is fixed together, the type and thickness of the baffle material (the sheet of wood to which the speaker is mounted), and the way this baffle is mounted to the cab" all affect the sound and tone of the cabinet.[24]

When two or more speakers are used in the same cabinet, or when two cabinets are used together, the speakers can be wired in parallel or in series, or in a combination of the two (e.g., two 2x10" cabinets, with the two speakers wired in series, can be connected together in parallel). Whether speakers are wired in parallel or in series affects the impedance of the system. Two 8 ohm speakers wired in parallel will have a 4 ohm impedance. Guitarists who are connecting multiple cabinets to their amplifier need to consider the minimum impedance of their amplifier. Whether speakers are wired in parallel or in series also affects the tone and sound. When speakers are wired in parallel, this "...dampen[s] and restrain[s]" the speakers, giving a "tighter response, and a smoother breakup"; speakers that are wired in "...series (usually no more than two) run a little looser, giving a slightly more raw, open and edgy sound."[24]

For electric guitar amplifiers, there is often a distinction between "practice" or "recording studio" guitar amps, which tend to have output power ratings of less than one watt to 20 watts and "performance" or "stage" amps, which are generally 30 watts or higher. Traditionally, these have been fixed-power amplifiers, with some models having a half-power switch to slightly reduce the listening volume while preserving power-tube distortion.

The relationship between perceived volume and power output in watts is not immediately obvious. While beginners sometimes assume that there is a linear relationship between perceived volume and wattage (e.g., they assume that a 5-watt amp will be much quieter at its maximum output than a 50-watt amp), in fact the human ear perceives a 5-watt amplifier as half as loud as a 50-watt amplifier (a tenfold increase in power), and a half-watt amplifier is a quarter as loud as a 50-watt amp. Doubling the power of an amplifier results in a "just noticeable" increase in volume, so a 100-watt amplifier is only just noticeably louder than a 50-watt amplifier. Such generalizations are also subject to the human ear's tendency to behave as a natural compressor at high volumes.

Power attenuation can be used with either low-power or high-power amplifiers, resulting in variable-power amplifiers. A high-power amplifier with power attenuation can produce power-tube distortion through a range of listening volumes, but with a decrease in high power distortion. Other technologies, such as dual rectifiers and the Sag Circuit—which should not be confused with attenuation—allow high power amplifiers to produce low power volume while preserving high power distortion.[25]

Speaker efficiency is also a major factor affecting a tube amplifier's maximum volume. For bass instruments, higher-power amplifiers are needed to reproduce low-frequency sounds. While an electric guitarist would be able to play at a small club with a 50-watt amplifier, a bass player performing in the same venue would probably need an amplifier with 200 or more watts.

Marshall is a popular amplifier manufacturer for metal and hard rock. Pictured is the MG15DFX guitar amplifier.

Distortion is a feature available on many guitar amplifiers that is not typically found on keyboard or bass guitar amplifiers. Tube guitar amplifiers can produce distortion through pre-distortion equalization, preamp tube distortion, post-distortion EQ, power-tube distortion, tube rectifier compression, output transformer distortion, guitar speaker distortion, and guitar speaker and cabinet frequency response. Because there are so many factors beyond preamp distortion that create a guitarist's "signature sound", in recording and sound reinforcement applications, the sound of the guitar amp is almost always recorded with a microphone placed in front of the guitar speaker, rather than using the guitar amp's pre-amp out signal (even though the guitar sound is typically recorded with a mic in front of the amp's speaker, for recordings, the sound engineer or music producer may ask for the DI out signal from the pickups to be recorded onto a separate track at the same time, so that the engineer or producer can re-amp the signal through various different amps at a later time). In contrast, it is fairly common to use a DI box with electric bass.

Distortion sound or "texture" from guitar amplifiers is further shaped or processed through the frequency response and distortion factors in the microphones (their response, placement, and multi-microphone comb filtering effects), microphone preamps, mixer channel equalization, and compression. Additionally, the basic sound produced by the guitar amplifier can be changed and shaped by adding distortion and/or equalization effect pedals before the amp's input jack, in the effects loop just before the tube power amp, or after the power tubes.

Power-tube distortion is required for amp sounds in some genres. In a standard master-volume guitar amp, as the amp's final or master volume is increased beyond the full power of the amplifier, power tube distortion is produced. The "power soak" approach places the attenuation between the power tubes and the guitar speaker. In the re-amped or "dummy load" approach, the tube power amp drives a mostly resistive dummy load while an additional low power amp drives the guitar speaker. In the isolation box approach, the guitar amplifier is used with a guitar speaker in a separate cabinet. A soundproofed isolation cabinet, isolation box, isolation booth, or isolation room can be used.

Even in the 2010s, the vintage Fender Bandmaster remains a sought-after amp by guitarists. Note the four inputs, two for regular sound and two which are run through the onboard vibrato effect unit. The amp pictured is a 1968 model.

A variety of labels are used for level attenuation potentiometers (knobs) in a guitar amplifier and other guitar equipment. Electric guitars and basses have a volume control on the instrument that attenuates the signal from selected pickups. There may be two volume controls on an electric guitar or bass, wired in parallel to mix the signal levels from the neck and bridge pickups. Rolling back the guitar's volume control also changes the pickup's equalization or frequency response, which can provide pre-distortion equalization.

The simplest guitar amplifiers, such as some vintage amps and modern practice amps, have only a single volume control. Most have two volume controls: a first volume control called "preamplifier" or "gain" and a master volume control. The preamp or gain control is designed differently on different types of guitar amps. On an amp designed for an acoustic guitar, turning up the preamp knob will preamplify the signal, but even at its maximum setting, the preamp control is unlikely to produce much overdrive. However, with amps designed for electric guitarists playing electric blues, hard rock and heavy metal music, turning up the preamp or gain knob will usually produce overdrive or distortion. Some electric guitar amps have three controls in the volume section: preamplifier, distortion and master control. Turning up the preamp and distortion knobs in varying combinations can create a range of overdrive tones, from a gentle, warm growling overdrive suitable for a traditional blues show or a rockabilly band to the extreme distortion used in hardcore punk and death metal. On some electric guitar amps, the "gain" knob is equivalent to the distortion control on a distortion pedal, and similarly may have a side-effect of changing the proportion of bass and treble sent to the next stage.

The patch bay at the rear panel of this Line 6 Flextone guitar amp provides a number of additional inputs and outputs, including stereo XLR DI unit outputs.

A simple, inexpensive amplifier may have only two tone controls, a passive bass and treble control. In some better quality amps, one or more midrange controls are provided. On the most expensive amps, there may be shelving equalizers for bass and treble, a number of mid-range controls (e.g., low mid, mid and high mid), and a graphic equalizer or parametric equalizer. The amplifier's master volume control restricts the amount of signal permitted through to the driver stage and the power amplifier. When using a power attenuator with a tube amplifier, the master volume no longer acts as the master volume control. Instead, the power attenuator's attenuation control controls the power delivered to the speaker, and the amplifier's master volume control determines the amount of power-tube distortion. Power-supply based power reduction is controlled by a knob on the tube power amp, variously labeled "wattage", "power", "scale", "power scale", or "power dampening".

An electric guitar is a fretted stringed instrument with a neck and body that uses a pickup to convert the vibration of its strings into electrical signals. The vibration occurs when a guitarist strums, plucks or fingerpicks the strings. It is sensed by a pickup, most commonly by a magnetic pickup that uses the principle of direct electromagnetic induction. The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear. The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound. Often the signal is modified using effects such as reverb and distortion and "overdrive", with the growling sound of the latter being a key element of the sound of the electric guitar as it is used in blues and rock music.

Invented in 1931, the amplified electric guitar was adopted by jazz guitarists, who sought to be able to do single-note guitar solos in large big band ensembles. Early proponents of the electric guitar on record included Les Paul, Lonnie Johnson, Sister Rosetta Tharpe, T-Bone Walker, and Charlie Christian. During the 1950s and 1960s, the electric guitar became the most important instrument in pop music.[1] It has evolved into an instrument that is capable of a multitude of sounds and styles in genres ranging from pop and rock to country music, blues and jazz. It served as a major component in the development of electric blues, rock and roll, rock music, heavy metal music and many other genres of music.

Electric guitar design and construction vary greatly in the shape of the body and the configuration of the neck, bridge, and pickups. Guitars may have a fixed bridge or a spring-loaded hinged bridge that lets players "bend" the pitch of notes or chords up or down or perform vibrato effects. The sound of a guitar can be modified by new playing techniques such as string bending, tapping, hammering on, using audio feedback, or slide guitar playing. There are several types of electric guitar, including the solid-body guitar, various types of hollow-body guitars, the six-string guitar (the most common type, usually tuned E, A, D, G, B, E, from lowest to highest strings), the seven-string guitar, which typically adds a low B string below the low E, and the twelve-string electric guitar, which has six pairs of strings.

Popular music and rock groups often use the electric guitar in two roles: as a rhythm guitar, which plays the chord sequence or progression and riffs and sets the beat (as part of a rhythm section), and as a lead guitar, which is used to perform instrumental melody lines, melodic instrumental fill passages, and solos. In a small group, such as a power trio, one guitarist switches between both roles. In larger rock and metal bands, there is often a rhythm guitarist and a lead guitarist.

Many experiments at electrically amplifying the vibrations of a string instrument were made dating back to the early part of the 20th century. Patents from the 1910s show telephone transmitters were adapted and placed inside violins and banjos to amplify the sound. Hobbyists in the 1920s used carbon button microphones attached to the bridge; however, these detected vibration from the bridge on top of the instrument, resulting in a weak signal.[2] With numerous people experimenting with electrical instruments in the 1920s and early 1930s, there are many claimants to have been the first to invent an electric guitar.

The "Frying Pan", 1932

Electric guitars were originally designed by acoustic guitar makers and instrument manufacturers. Some of the earliest electric guitars adapted hollow-bodied acoustic instruments and used tungsten pickups. The first electrically amplified guitar was designed in 1931 by George Beauchamp, the general manager of the National Guitar Corporation, with Paul Barth, who was vice president.[3] The maple body prototype for the one-piece cast aluminium "frying pan" was built by Harry Watson, factory superintendent of the National Guitar Corporation.[3] Commercial production began in late summer of 1932 by the Ro-Pat-In Corporation (Electro-Patent-Instrument Company), in Los Angeles,[4][5] a partnership of Beauchamp, Adolph Rickenbacker (originally Rickenbacher), and Paul Barth.[6] In 1934, the company was renamed the Rickenbacker Electro Stringed Instrument Company. In that year Beauchamp applied for a United States patent for an Electrical Stringed Musical Instrument and the patent was issued in 1937.[7][8][9][10]

By early-mid 1935, Electro String Instrument Corporation had achieved mainstream success with the A-22 Frying Pan, and set out to capture a new audience through its release of the "Electro-Spanish Model B" and the "Electro-Spanish Ken Roberts" which was the first full 25" scale electric guitar produced.[7][8][9][10] The Electro-Spanish Ken Roberts provided players a full 25" scale, with 17 frets free of the fretboard. It is estimated that fewer than 50 Electro-Spanish Ken Roberts were constructed between 1933 and 1937; fewer than 10 are known to survive today.[7][8][9][10]

The need for the amplified guitar became apparent during the big band era as orchestras increased in size, particularly when acoustic guitars had to compete with large, loud brass sections. The first electric guitars used in jazz were hollow archtop acoustic guitar bodies with electromagnetic transducers. Early electric guitar manufacturers include Rickenbacker in 1932; Dobro in 1933; National, AudioVox and Volu-tone in 1934; Vega, Epiphone (Electrophone and Electar), and Gibson in 1935 and many others by 1936.

Fender Stratocaster is one of the most often emulated electric guitar shapes[11][12]

The solid-body electric guitar is made of solid wood, without functionally resonating air spaces. The first solid-body Spanish standard guitar was offered by Vivi-Tone no later than 1934. This model featured a guitar-shaped body of a single sheet of plywood affixed to a wood frame. Another early, substantially solid Spanish electric guitar, called the Electro Spanish, was marketed by the Rickenbacker guitar company in 1935 and made of Bakelite. By 1936, the Slingerland company introduced a wooden solid-body electric model, the Slingerland Songster 401 (and a lap steel counterpart, the Songster 400).

The earliest documented performance with an electrically amplified guitar was in 1932, by Gage Brewer, a musician based in Wichita, Kansas.[2] He had an Electric Hawaiian A-25 (frypan, lap steel) and a standard Electric Spanish from George Beauchamp of Los Angeles. Brewer publicized his new instruments in an article in the Wichita Beacon of 2 October 1932 and through performances that month. The first recordings using the electric guitar were by Hawaiian-style players, in 1933. Bob Dunn of Milton Brown's Musical Brownies introduced the electric Hawaiian guitar to Western swing with his January 1935 Decca recordings, departing almost entirely from the Hawaiian musical influence and heading towards jazz and blues. Alvino Rey was an artist who took this instrument to a wide audience in a large orchestral setting and later developed the pedal steel guitar for Gibson. An early proponent of the electric Spanish guitar was jazz guitarist George Barnes, who used the instrument in two songs recorded in Chicago on 1 March 1938, "Sweetheart Land" and "It's a Low-Down Dirty Shame". Some incorrectly attribute the first recording to Eddie Durham, but his recording with the Kansas City Five was made 15 days later.[13] Durham introduced the instrument to a young Charlie Christian, who made the instrument famous in his brief life and would be a major influence on jazz guitarists for decades thereafter.[14]

Gibson's first production electric guitar, marketed in 1936, was the ES-150 model ("ES" for "Electric Spanish", and "150" reflecting the $150 price of the instrument, along with matching amplifier). The ES-150 guitar featured a single-coil, hexagonally shaped "bar" pickup, which was designed by Walt Fuller. It became known as the "Charlie Christian" pickup (named for the great jazz guitarist who was among the first to perform with the ES-150 guitar). The ES-150 achieved some popularity but suffered from unequal loudness across the six strings.

Early proponents of the electric guitar on record include Alvino Rey (Phil Spitalney Orchestra), Les Paul (Fred Waring Orchestra), Danny Stewart (Andy Iona Orchestra), George Barnes (under many aliases), Lonnie Johnson, Floyd Smith, Big Bill Broonzy, T-Bone Walker, George Van Eps, Charlie Christian (Benny Goodman Orchestra), Tampa Red, Memphis Minnie, and Arthur Crudup.

A functionally solid-body electric guitar was designed and built in 1940 by Les Paul from an Epiphone acoustic archtop. His "log guitar" (so called because it consisted of a simple 4x4 wood post with a neck attached to it and homemade pickups and hardware, with two detachable Epiphone hollow-body halves attached to the sides for appearance only) shares nothing in design or hardware with the solid-body Gibson Les Paul introduced in 1952. However, the feedback associated with hollow-bodied electric guitars was understood long before Paul's "log" was created in 1940; Gage Brewer's Ro-Pat-In of 1932 had a top so heavily reinforced that it essentially functioned as a solid-body instrument.[2] In 1945, Richard D. Bourgerie made an electric guitar pickup and amplifier for professional guitar player George Barnes. Bourgerie worked through World War II at Howard Radio Company, making electronic equipment for the American military. Barnes showed the result to Les Paul, who then arranged for Bourgerie to have one made for him.

This table shows the layout of pitches on a standard tuning six-string guitar, which is tuned E, A, D, G, B, E, going from the lowest-pitch, thickest string to the highest - pitch, thinnest string. The table depicts a guitar fretboard as it would appear to an observer looking at a guitar that is on its side and upside-down, thus giving the table the same appearance that a guitarist would see when holding the instrument in playing position. Zero is the nut; 5 is the fifth (tuning) fret. This table only shows up to the twelfth fret. Most electric guitars have additional frets beyond the twelfth fret which have the same layout as the 1st- 12th fret (although the notes are an octave higher in pitch).

Electric guitar design and construction vary greatly in the shape of the body and the configuration of the neck, bridge, and pickups. However, some features are present on most guitars. The photo below shows the different parts of an electric guitar. The headstock (1) contains the metal machine heads (1.1), which use a worm gear for tuning. The nut (1.4)—a thin fret-like strip of metal, plastic, graphite or bone—supports the strings at the headstock end of the instrument. The frets (2.3) are thin metal strips that stop the string at the correct pitch when the player pushes a string against the fingerboard. The truss rod (1.2) is a metal rod (usually adjustable) that counters the tension of the strings to keep the neck straight. Position markers (2.2) provide the player with a reference to the playing position on the fingerboard.[15]

The neck and fretboard (2.1) extend from the body. At the neck joint (2.4), the neck is either glued or bolted to the body. The body (3) is typically made of wood with a hard, polymerized finish. Strings vibrating in the magnetic field of the pickups (3.1, 3.2) produce an electric current in the pickup winding that passes through the tone and volume controls (3.8) to the output jack. Some guitars have piezo pickups, in addition to or instead of magnetic pickups.

Some guitars have a fixed bridge (3.4). Others have a spring-loaded hinged bridge called a vibrato bar, tremolo bar, or whammy bar, which lets players bend notes or chords up or down in pitch or perform a vibrato embellishment. A plastic pickguard on some guitars protects the body from scratches or covers the control cavity, which holds most of the wiring. The degree to which the choice of woods and other materials in the solid-guitar body (3) affects the sonic character of the amplified signal is disputed. Many believe it is highly significant, while others think the difference between woods is subtle. In acoustic and archtop guitars, wood choices more clearly affect tone.

Woods typically used in solid-body electric guitars include alder (brighter, but well rounded), swamp ash (similar to alder, but with more pronounced highs and lows), mahogany (dark, bassy, warm), poplar (similar to alder), and basswood (very neutral).[16] Maple, a very bright tonewood,[16] is also a popular body wood, but is very heavy. For this reason it is often placed as a "cap" on a guitar made primarily of another wood. Cheaper guitars are often made of cheaper woods, such as plywood, pine or agathis—not true hardwoods—which can affect durability and tone. Though most guitars are made of wood, any material may be used. Materials such as plastic, metal, and even cardboard have been used in some instruments.

The guitar output jack typically provides a monaural signal. Many guitars with active electronics use a jack with an extra contact normally used for stereo. These guitars use the extra contact to break the ground connection to the on-board battery to preserve battery life when the guitar is unplugged. These guitars require a mono plug to close the internal switch and connect the battery to ground. Standard guitar cables use a high-impedance 1/4-inch (6.35-mm) mono plug. These have a tip and sleeve configuration referred to as a TS phone connector. The voltage is usually around 1 to 9 millivolts.

A few guitars feature stereo output, such as Rickenbacker guitars equipped with Rick-O-Sound. There are a variety of ways the "stereo" effect may be implemented. Commonly, but not exclusively, stereo guitars route the neck and bridge pickups to separate output buses on the guitar. A stereo cable then routes each pickup to its own signal chain or amplifier. For these applications, the most popular connector is a high-impedance 1/4-inch plug with a tip, ring and sleeve configuration, also known as a TRS phone connector. Some studio instruments, notably certain Gibson Les Paul models, incorporate a low-impedance three-pin XLR connector for balanced audio. Many exotic arrangements and connectors exist that support features such as midi and hexaphonic pickups.

The bridge and tailpiece, while serving separate purposes, work closely together to affect playing style and tone. There are four basic types of bridge and tailpiece systems on electric guitars. Within these four types are many variants.

A hard-tail guitar bridge anchors the strings at or directly behind the bridge and is fastened securely to the top of the instrument.[17] These are common on carved-top guitars, such as the Gibson Les Paul and the Paul Reed Smith models, and on slab-body guitars, such as the Music Man Albert Lee and Fender guitars that are not equipped with a vibrato arm.

A floating or trapeze tailpiece (similar to a violin's) fastens to the body at the base of the guitar. These appear on Rickenbackers, Gretsches, Epiphones, a wide variety of archtop guitars, particularly Jazz guitars, and the 1952 Gibson Les Paul.[18]

Pictured is a tremolo arm or vibrato tailpiece style bridge and tailpiece system, often called a whammy bar or trem. It uses a lever ("vibrato arm") attached to the bridge that can temporarily slacken or tighten the strings to alter the pitch. A player can use this to create a vibrato or a portamento effect. Early vibrato systems were often unreliable and made the guitar go out of tune easily. They also had a limited pitch range. Later Fender designs were better, but Fender held the patent on these, so other companies used older designs for many years.

With expiration of the Fender patent on the Stratocaster-style vibrato, various improvements on this type of internal, multi-spring vibrato system are now available. Floyd Rose introduced one of the first improvements on the vibrato system in many years when, in the late 1970s, he experimented with "locking" nuts and bridges that prevent the guitar from losing tuning, even under heavy vibrato bar use.

Tune-o-matic with "strings through the body" construction (without stopbar)

The fourth type of system employs string-through body anchoring. The strings pass over the bridge saddles, then through holes through the top of the guitar body to the back. The strings are typically anchored in place at the back of the guitar by metal ferrules. Many believe this design improves a guitar's sustain and timbre. A few examples of string-through body guitars are the Fender Telecaster Thinline, the Fender Telecaster Deluxe, the B.C. Rich IT Warlock and Mockingbird, and the Schecter Omen 6 and 7 series.

Main article: Pickup (music technology)

Compared to an acoustic guitar, which has a hollow body, electric guitars make much less audible sound when their strings are plucked, so electric guitars are normally plugged into a guitar amplifier and speaker. When an electric guitar is played, string movement produces a signal by generating (i.e., inducing) a small electric current in the magnetic pickups, which are magnets wound with coils of very fine wire. The signal passes through the tone and volume circuits to the output jack, and through a cable to an amplifier.[19] The current induced is proportional to such factors as string density and the amount of movement over the pickups.

Pickups on a Fender Squier "Fat Strat" guitar—a "humbucker" pickup on the left and two single-coil pickups on the right.

Because in most cases it is desirable to isolate coil-wound pickups from the unintended sound of internal vibration of loose coil windings, a guitar's magnetic pickups are normally embedded or "potted" in wax, lacquer, or epoxy to prevent the pickup from producing a microphonic effect. Because of their natural inductive qualities, all magnetic pickups tend to pick up ambient, usually unwanted electromagnetic interference or EMI.[20] The resulting hum is particularly strong with single-coil pickups, and it is aggravated by the fact that many vintage guitars are insufficiently shielded against electromagnetic interference. The most common source is 50- or 60-Hz hum from power transmission systems (house wiring, etc.). Since nearly all amplifiers and audio equipment associated with electric guitars must be plugged in, it is a continuing technical challenge to reduce or eliminate unwanted hum.[21]

Double-coil or "humbucker" pickups were invented as a way to reduce or counter the unwanted ambient hum sounds (known as 60-cycle hum). Humbuckers have two coils of opposite magnetic and electric polarity to produce a differential signal. Electromagnetic noise that hits both coils equally tries to drive the pickup signal toward positive on one coil and toward negative on the other, which cancels out the noise. The two coils are wired in phase, so their signal adds together. This high combined inductance of the two coils leads to the richer, "fatter" tone associated with humbucking pickups.

Piezoelectric pickups use a "sandwich" of quartz crystal or other piezoelectric material, typically placed beneath the string saddles or nut. These devices respond to pressure changes from all vibration at these specific points.

Optical pickups are a type of pickup that sense string and body vibrations using infrared LED light. These pickups are not sensitive to EMI.

Some "hybrid" electric guitars are equipped with additional microphone, piezoelectric, optical, or other types of transducers to approximate an acoustic instrument tone and broaden the sonic palette of the instrument.

Electric guitar necks vary in composition and shape. The primary metric of guitar necks is the scale length, which is the vibrating length of the strings from nut to bridge. A typical Fender guitar uses a 25.5-inch scale length, while Gibson uses a 24.75-inch scale length in their Les Paul. While the scale length of the Les Paul is often described as 24.75 inches, it has varied through the years by as much as a half inch.[citation needed]

Frets are positioned proportionally to scale length—the shorter the scale length, the closer the fret spacing. Opinions vary regarding the effect of scale length on tone and feel. Popular opinion holds that longer scale length contributes to greater amplitude. Reports of playing feel are greatly complicated by the many factors involved in this perception. String gauge and design, neck construction and relief, guitar setup, playing style and other factors contribute to the subjective impression of playability or feel.

A bolt-on neck

Necks are described as bolt-on, set-in, or neck-through, depending on how they attach to the body. Set-in necks are glued to the body in the factory. They are said to have a warmer tone and greater sustain.[citation needed] This is the traditional type of joint. Leo Fender pioneered bolt-on necks on electric guitars to facilitate easy adjustment and replacement. Neck-through instruments extend the neck the length of the instrument, so that it forms the center of the body, and are known for long sustain and for being particularly sturdy.[citation needed] While a set-in neck can be carefully unglued by a skilled luthier, and a bolt-on neck can simply be unscrewed, a neck-through design is difficult or even impossible to repair, depending on the damage. Historically, the bolt-on style has been more popular for ease of installation and adjustment. Since bolt-on necks can be easily removed, there is an after-market in replacement bolt-on necks from companies such as Warmoth and Mighty Mite. Some instruments—notably most Gibson models—continue to use set-in glued necks. Neck-through bodies are somewhat more common in bass guitars.

Materials for necks are selected for dimensional stability and rigidity, and some allege that they influence tone. Hardwoods are preferred, with maple, mahogany, and ash topping the list. The neck and fingerboard can be made from different materials; for example, a guitar may have a maple neck with a rosewood or ebony fingerboard. In the 1970s, designers began to use exotic man-made materials such as aircraft-grade aluminum, carbon fiber, and ebonol. Makers known for these unusual materials include John Veleno, Travis Bean, Geoff Gould, and Alembic.

Aside from possible engineering advantages, some feel that in relation to the rising cost of rare tonewoods, man-made materials may be economically preferable and more ecologically sensitive. However, wood remains popular in production instruments, though sometimes in conjunction with new materials. Vigier guitars, for example, use a wooden neck reinforced by embedding a light, carbon fiber rod in place of the usual heavier steel bar or adjustable steel truss rod. After-market necks made entirely from carbon fiber fit existing bolt-on instruments. Few, if any, extensive formal investigations have been widely published that confirm or refute claims over the effects of different woods or materials on electric guitar sound.

A neck-through bass guitar

Several neck shapes appear on guitars, including shapes known as C necks, U necks, and V necks. These refer to the cross-sectional shape of the neck (especially near the nut). Several sizes of fret wire are available, with traditional players often preferring thin frets, and metal shredders liking thick frets. Thin frets are considered better for playing chords, while thick frets allow lead guitarists to bend notes with less effort.

An electric guitar with a folding neck called the "Foldaxe" was designed and built for Chet Atkins by Roger C. Field.[22]Steinberger guitars developed a line of exotic, carbon fiber instruments without headstocks, with tuning done on the bridge instead.

Fingerboards vary as much as necks. The fingerboard surface usually has a cross-sectional radius that is optimized to accommodate finger movement for different playing techniques. Fingerboard radius typically ranges from nearly flat (a very large radius) to radically arched (a small radius). The vintage Fender Telecaster, for example, has a typical small radius of approximately 7.25 inches. Some manufacturers have experimented with fret profile and material, fret layout, number of frets, and modifications of the fingerboard surface for various reasons. Some innovations were intended to improve playability by ergonomic means, such as Warmoth Guitars' compound radius fingerboard. Scalloped fingerboards added enhanced microtonality during fast legato runs. Fanned frets intend to provide each string with an optimal playing tension and enhanced musicality. Some guitars have no frets—and others, like the Gittler guitar, have no neck in the traditional sense.

While an acoustic guitar's sound depends largely on the vibration of the guitar's body and the air inside it, the sound of an electric guitar depends largely on the signal from the pickups. The signal can be "shaped" on its path to the amplifier via a range of effect devices or circuits that modify the tone and characteristics of the signal. Amplifiers and speakers also add coloration to the final sound.

Electric guitars usually have one to four magnetic pickups. Identical pickups produce different tones depending on how near they are to the neck or bridge. Bridge pickups produce a bright or trebly timbre, and neck pickups are warmer or more bassy. The type of pickup also affects tone. Dual-coil pickups sound warm, thick, perhaps even muddy; single-coil pickups sound clear, bright, perhaps even biting. Guitars don't require a uniform pickup type: a common mixture is the "fat Strat" arrangement of one dual-coil at the bridge position and single coils in the middle and neck positions, known as HSS (humbucker/single/single). Some guitars have piezoelectric pickup in addition to electromagnetic pickups. Piezo pickups produce a more acoustic sound. The piezo runs through a built-in equalizer (EQ) to improve similitude and control tone. A blend knob controls the mix between electromagnetic and piezoelectric sounds.

Where there is more than one pickup, a pickup selector switch is usually present. These typically select or combine the outputs of two or more pickups, so that two-pickup guitars have three-way switches, and three-pickup guitars have five-way switches (a Gibson Les Paul three-pickup Black Beauty has a three-position toggle switch which configures bridge, bridge and middle [switch in middle position] and neck pickups). Further circuitry sometimes combines pickups in different ways. For instance, phase switching places one pickup out of phase with the other(s), leading to a "honky", "nasal", or "funky" sound. Individual pickups can also have their timbre altered by switches, typically coil tap switches that effectively short-circuit some of a dual-coil pickup's windings to produce a tone similar to a single-coil pickup (usually done with push-pull volume knobs).

The final stages of on-board sound-shaping circuitry are the volume control (potentiometer) and tone control (which "rolls off" the treble frequencies). Where there are individual volume controls for different pickups, and where pickup signals can be combined, they would affect the timbre of the final sound by adjusting the balance between pickups from a straight 50:50.

The strings fitted to the guitar also have an influence on tone. Rock musicians often prefer the lightest gauge of roundwound string, which is easier to bend, while jazz musicians go for heavier, flatwound strings, which have a rich, dark sound. Steel, nickel, and cobalt are common string materials, and each gives a slightly different tone color. Recent guitar designs may incorporate much more complex circuitry than described above; see Digital and synthesizer guitars, below.

The solid-body electric guitar does not produce enough sound to be audible to the audience in a performance setting without it being plugged into an electronic amplifier (exceptions would be when a guitarist is doing a sound recording and plugs into the mixing console or when a bassist plugs directly into the PA system in a live show).

Guitar amplifiers are designed with a different approach than that used to design sound reinforcement system power amplifiers and home "hi-fi" stereo systems. Audio amplifiers generally are intended to accurately reproduce the source signal without adding unwanted tonal coloration (i.e., they have a flat frequency response) or unwanted distortion. In contrast, most guitar amplifiers are intended to provide tonal coloration and/or overdrive (distortion of various types) that can add to a guitar signal. A common tonal coloration sought by guitarists is rolling off some of the high frequencies. Along with a guitarist's playing style and choice of electric guitar and pickups, the choice of guitar amp model is a key part of a guitarist's unique tone. Many top guitarists are associated with a specific brand of guitar amp. As well, electric guitarists in blues, rock and many related sub-genres often intentionally choose amplifiers or effects units with controls that distort or alter the sound (to a greater or lesser degree).

In the 1950s and 1960s, some guitarists began exploring a wider range of tonal effects by distorting the sound of the instrument. To do this, they used overdrive — increasing the gain of the preamplifier beyond the level where the signal could be reproduced with little distortion, resulting in a "fuzzy" sound. This effect is called "clipping" by sound engineers, because when viewed with an oscilloscope, the wave forms of a distorted signal appear to have had their peaks "clipped off", in the process introducing additional tones (often approximating the harmonics characteristic of a square wave of that basic frequency). This was not actually a new development in the musical instrument or its supporting gear, but rather a shift of aesthetics, such sounds not having been thought desirable previously. Some distortion modes with an electric guitar increase the sustain of single notes and chords, which changes the sound of the instrument. In particular, distortion made it more feasible to perform guitar solos that used long, sustained notes.

After distortion became popular amongst rock music groups, guitar amplifier manufacturers included various provisions for it as part of amplifier design, making amps easier to overdrive, and providing separate "dirty" and "clean" channels so that distortion could easily be switched on and off. The distortion characteristics of vacuum tube amplifiers are particularly sought-after in blues and many rock music genres, and various attempts have been made to emulate them without the disadvantages (e.g., fragility, low power, expense) of actual tubes. Distortion, especially in tube based amplifiers, can come from several sources: power supply sag as more power is demanded than the supply can provide at a steady voltage, deliberate gain over drive of active elements, or alterations in the feedback provisions for various circuit stages.[23]

Guitar amplifiers have long included at least a few effect units, often tone controls for bass and treble, an integrated tremolo system (sometimes incorrectly labeled (and marketed) as vibrato), and/or a mechanical spring reverb unit. In the 2010s, guitar amps often have onboard distortion effects. Some 2010-era amps provide multiple effects, such as chorus, flanger, phaser and octave down effects. The use of offboard effects such as stompbox pedals is made possible by either plugging the guitar into the external effect pedal and then plugging the effect pedal into the amp, or by using one or more effects loops, an arrangement that allows effects to be electrically or mechanically switched in or out of the signal path as desired. In the signal chain, the effects loop is typically located between the preamplifier stage and the power amplifier stages (though reverb units generally precede the effects loop if both are featured on an amplifier). This allows the guitarist to apply modulation effects to the signal after it has been processed through the preamplifier, something generally desirable, particularly with time-based effects such as delay. By the 2010s, guitar amplifiers usually included a distortion effect. Effects circuitry (whether internal to an amplifier or not) can be taken as far as amp modeling, by which is meant alteration of the electrical and audible behavior in such a way as to make an amp sound as though it were another (or one of several) amplifiers. When done well, a solid state amplifier can sound like a tube amplifier (even one with power supply sag), reducing the need to manage more than one amp. Some modeling systems even attempt to emulate the sound of different speakers/cabinets. Nearly all amp and speaker cabinet modeling is done digitally, using computer techniques (e.g., Digital Signal Processing or DSP circuitry and software). There is disagreement about whether this approach is musically satisfactory, and also whether this or that unit is more or less successful than another.[24][25]

In the 1960s, the tonal palette of the electric guitar was further modified by introducing effect units in its signal path, before the guitar amp, of which one of the earliest units was the fuzz pedal. Effects units come in several formats, the most common of which are the stompbox "pedal" and the rackmount unit. A stomp box (or pedal) is a small metal or plastic box containing the circuitry, which is placed on the floor in front of the musician and connected in line with the patch cord connected to the instrument. The box is typically controlled by one or more foot-pedal on-off switches and it typically contains only one or two effects. Pedals are smaller than rackmount effects and usually less expensive. "Guitar pedalboards" are used by musicians who use multiple stomp-boxes; these may be a DIY project made with plywood or a commercial stock or custom-made pedalboard.

A rackmount effects unit may contain an electronic circuit nearly identical to a stompbox-based effect, but it is mounted in a standard 19" equipment rack, which is usually mounted in a road case that is designed to protect the equipment during transport. More recently, as signal-processing technology continuously becomes more feature-dense, rack-mount effects units frequently contain several types of effects. They are typically controlled by knobs or switches on the front panel, and often by a MIDI digital control interface.

Typical effects include:

In the 1970s, as effects pedals proliferated, their sounds were combined with tube amp distortion at lower, more controlled volumes by using power attenuators, such as Tom Scholz's Power Soak, as well as re-amplified dummy loads, such as Eddie Van Halen's use of dummy-load power resistor, post-power-tube effects, and a final solid-state amp driving the guitar speakers.

Recent amplifiers may include digital technology similar to modern effects pedals, including the ability to model or emulate a variety of classic amps.

The Zoom 505 multi-effect pedal

A multi-effects device (also called a "multi-FX" device) is a single electronics effects pedal or rack-mount device that contains many electronic effects. In the late 1990s and throughout the 2000s, multi-FX manufacturers such as Zoom and Korg produced devices that were increasingly feature-laden. Multi-FX devices combine several effects together, and most devices allow users to use preset combinations of effects, including distortion, chorus, reverb, compression, and so on. This allows musicians to have quick on-stage access to different effects combinations. Some multi-FX pedals contain modelled versions of well-known effects pedals or amplifiers.

The Boss GT-8, a higher-end multi-effect processing pedal; note the preset switches and patch bank foot switches and built-in expression pedal.

Multi-effects devices have garnered a large share of the effects device market, because they offer the user such a large variety of effects in a single package. A low-priced multi-effects pedal may provide 20 or more effects for the price of a regular single-effect pedal. More expensive multi-effect pedals may include 40 or more effects, amplifier modelling, and the ability to combine effects and/or modelled amp sounds in different combinations, as if the user was using multiple guitar amps. More expensive multi-effects pedals may also include more input and output jacks (e.g., an auxiliary input or a "dry" output), MIDI inputs and outputs, and an expression pedal, which can control volume or modify effect parameters (e.g., the rate of the simulated rotary speaker effect).

By the 1980s and 1990s, software effects became capable of replicating the analog effects used in the past. These new digital effects attempt to model the sound produced by analog effects and tube amps, with varying degrees of quality. There are many free guitar effects computer programs that can be downloaded from the Internet. Now, computers with sound cards can be used as digital guitar effects processors. Although digital and software effects offer many advantages, many guitarists still use analog effects.

In 2002, Gibson announced the first digital guitar, which performs analog-to-digital conversion internally. The resulting digital signal is delivered over a standard Ethernet cable, eliminating cable-induced line noise. The guitar also provides independent signal processing for each individual string. In 2003, modelling amplifier maker Line 6 introduced the Variax guitar. It differs in some fundamental ways from conventional solid-body electrics. It has on-board electronics capable of modelling the sound of a variety of unique guitars and some other stringed instruments. At one time, some models featured piezoelectric pickups instead of the conventional electromagnetic pickups.

A prepared guitar

The sound of a guitar can not only be adapted by electronic sound effects but is also heavily affected by various new techniques developed or becoming possible in combination with electric amplification. This is called extended technique.

Extended techniques include:

The hammer-on technique Palm muting of the strings using the picking hand Slide guitar

Other techniques, such as axial finger vibrato, pull-offs, hammer-ons, palm muting, harmonics and altered tunings, are also used on the classical and acoustic guitar. Shred guitar is a genre involving a number of extended techniques.

Unlike acoustic guitars, solid-body electric guitars have no vibrating soundboard to amplify string vibration. Instead, solid-body instruments depend on electric pickups and an amplifier (or amp) and speaker. The solid body ensures that the amplified sound reproduces the string vibration alone, thus avoiding the wolf tones and unwanted feedback associated with amplified acoustic guitars of the period. These guitars are generally made of hardwood covered with a hard polymer finish, often polyester or lacquer. In large production facilities, the wood is stored for three to six months in a wood-drying kiln before being cut to shape. Premium custom-built guitars are frequently made with much older, hand-selected wood.[citation needed]

One of the first solid-body guitars was invented by Les Paul. Gibson did not present their Gibson Les Paul guitar prototypes to the public, as they did not believe the solid-body style would catch on. Another early solid-body Spanish style guitar, resembling what would become Gibson's Les Paul guitar a decade later, was developed in 1941 by O.W. Appleton, of Nogales, Arizona.[27] Appleton made contact with both Gibson and Fender but was unable to sell the idea behind his "App" guitar to either company.[28] In 1946, Merle Travis commissioned steel guitar builder Paul Bigsby to build him a solid-body Spanish-style electric.[29] Bigsby delivered the guitar in 1948. The first mass-produced solid-body guitar was Fender Esquire and Fender Broadcaster (later to become the Fender Telecaster), first made in 1948, five years after Les Paul made his prototype. The Gibson Les Paul appeared soon after to compete with the Broadcaster.[30] Another notable solid-body design is the Fender Stratocaster, which was introduced in 1954 and became extremely popular among musicians in the 1960s and 1970s for its wide tonal capabilities and more comfortable ergonomics than other models.

Some solid-bodied guitars, such as the Gibson Les Paul Supreme, the PRS Singlecut, and the Fender Telecaster Thinline, among others, are built with hollows in the body. These hollows are designed specifically not to interfere with the critical bridge and string anchor point on the solid body. In the case of Gibson and PRS, these are called chambered bodies. The motivation for this may be to reduce weight, to achieve a semi-acoustic tone (see below) or both.[31][32][33]

Main article: Semi-acoustic guitar Epiphone semi-acoustic hollow-body guitar

Semi-acoustic guitars have a hollow body (similar in depth to a solid-body guitar) and electronic pickups mounted on the body. They work in a similar way to solid-body electric guitars except that, because the hollow body also vibrates, the pickups convert a combination of string and body vibration into an electrical signal. Whereas chambered guitars are made, like solid-body guitars, from a single block of wood, semi-acoustic and full-hollowbody guitars bodies are made from thin sheets of wood. They do not provide enough acoustic volume for live performance, but they can be used unplugged for quiet practice. Semi-acoustics are noted for being able to provide a sweet, plaintive, or funky tone. They are used in many genres, including blues, funk, sixties pop, and indie rock. They generally have cello-style F-shaped sound holes. These can be blocked off to prevent feedback, as in B. B. King's famous Lucille. Feedback can also be reduced by making them with a solid block in the middle of the soundbox.

Main article: Archtop guitar

Full hollow-body guitars have large, deep bodies made of glued-together sheets, or "plates", of wood. They can often be played at the same volume as an acoustic guitar and therefore can be used unplugged at intimate gigs. They qualify as electric guitars inasmuch as they have fitted pickups. Historically, archtop guitars with retrofitted pickups were among the very earliest electric guitars. The instrument originated during the Jazz Age, in the 1920s and 1930s, and are still considered the classic jazz guitar (nicknamed "jazzbox"). Like semi-acoustic guitars, they often have f-shaped sound holes.

Having humbucker pickups (sometimes just a neck pickup) and usually strung heavlly, jazzboxes are noted for their warm, rich tone. A variation with single-coil pickups, and sometimes with a Bigsby tremolo, has long been popular in country and rockabilly; it has a distinctly more twangy, biting tone than the classic jazzbox. The term archtop refers to a method of construction subtly different from the typical acoustic (or "folk" or "western" or "steel-string" guitar): the top is formed from a moderately thick (1 inch or 2–3 cm) piece of wood, which is then carved into a thin (0.1 in, or 2–3 mm) domed shape, whereas conventional acoustic guitars have a thin, flat top.

Main article: Acoustic-electric guitar

Some steel-string acoustic guitars are fitted with pickups purely as an alternative to using a separate microphone. They may also be fitted with a piezoelectric pickup under the bridge, attached to the bridge mounting plate, or with a low-mass microphone (usually a condenser mic) inside the body of the guitar that converts the vibrations in the body into electronic signals. Combinations of these types of pickups may be used, with an integral mixer/preamp/graphic equalizer. Such instruments are called electric acoustic guitars. They are regarded as acoustic guitars rather than electric guitars, because the pickups do not produce a signal directly from the vibration of the strings, but rather from the vibration of the guitar top or body.

Electric acoustic guitars should not be confused with semi-acoustic guitars, which have pickups of the type found on solid-body electric guitars, or solid-body hybrid guitars with piezoelectric pickups.

The one-string guitar is also known as the Unitar. Although rare, the one-string guitar is sometimes heard, particularly in Delta blues, where improvised folk instruments were popular in the 1930s and 1940s. Eddie "One String" Jones had some regional success.[citation needed] Mississippi blues musician Lonnie Pitchford played a similar, homemade instrument. In a more contemporary style, Little Willie Joe, the inventor of the Unitar, had a rhythm and blues instrumental hit in the 1950s with "Twitchy", recorded with the Rene Hall Orchestra.

The four-string guitar is better known as the tenor guitar. One of its best-known players was Tiny Grimes, who played on 52nd Street with the beboppers and played a major role in the Prestige Blues Swingers. Multi-instrumentalist Warren Ellis (musician) of Dirty Three and Nick Cave and the Bad Seeds is a contemporary player who includes a tenor guitar in his repertoire.

The four-string guitar is normally tuned CGDA, but some players, such as Tiny Grimes, tune to DGBE in order to preserve familiar 6-string guitar chord fingerings. The tenor guitar can also be tuned like a soprano, concert, or tenor ukulele, using versions of GCEA tuning.

Main article: Seven-string guitar Stephen Carpenter playing a 7-string electric guitar in 2009

Most seven-string guitars add a low B string below the low E. Both electric and classical guitars exist designed for this tuning. A high A string above the high E instead of the low B string is sometimes used. Another less common seven-string arrangement is a second G string situated beside the standard G string and tuned an octave higher, in the same manner as a twelve-stringed guitar (see below). Jazz guitarists using a seven-string include George Van Eps, Lenny Breau, Bucky Pizzarelli and his son John Pizzarelli.

Seven-string electric guitars were popularized among rock players in the 1980s by Steve Vai. Along with the Japanese guitar company Ibanez, Vai created the Universe series seven-string guitars in the 1980s, with a double locking tremolo system for a seven-string guitar. These models were based on Vai's six-string signature series, the Ibanez Jem. Seven-string guitars experienced a resurgence in popularity in the 2000s, championed by Deftones, Limp Bizkit, Slayer, KoRn, Fear Factory, Strapping Young Lad, Nevermore, Muse and other hard rock and metal bands. Metal musicians often prefer the seven-string guitar for its extended lower range. The seven-string guitar has also played an essential role in progressive metal rock and is commonly used in bands such as Dream Theater and Pain of Salvation and by experimental guitarists such as Ben Levin.

Main article: Eight-string guitar

Eight-string electric guitars are rare but not unused. One is played by Charlie Hunter, which was manufactured by Novax Guitars. The largest manufacturer of eight- to 14-string instruments is Warr Guitars. Their models are used by Trey Gunn (ex King Crimson), who has his own signature line from the company. Similarly, Mårten Hagström and Fredrik Thordendal of Meshuggah used 8-string guitars made by Nevborn Guitars and now guitars by Ibanez. Munky of the nu metal band KoRn is also known to use seven-string Ibanez guitars, and it is rumored that he is planning to release a K8 eight-string guitar similar to his K7 seven-string guitar. Another Ibanez player is Tosin Abasi, lead guitarist of the progressive metal band Animals as Leaders, who uses an Ibanez RG2228 to mix bright chords with very heavy low riffs on the seventh and eighth strings. Stephen Carpenter of Deftones also switched from a seven-string to an eight-string in 2008 and released his signature STEF B-8 with ESP Guitars. In 2008, Ibanez released the Ibanez RG2228-GK, which is the first mass-produced eight-string guitar. Jethro Tull's first album uses a nine-string guitar. Bill Kelliher, guitarist for the heavy metal group Mastodon, worked with First Act on a custom mass-produced nine-string guitar.

Main article: Ten-string guitar

B.C. Rich manufactures a ten-string six-course electric guitar, the Bich, whose radical shape positions the machine heads for the four secondary strings on the body, avoiding the head-heaviness of many electric twelve-string guitars. However many players bought it for the body shape or electrics and simply removed the extra strings. The company recognized this and released six-string models of the Bich, but ten-string models also remain in production.

Main article: Twelve-string guitar

Twelve-string electric guitars feature six pairs of strings, usually with each pair tuned to the same note. The extra E, A, D, and G strings add a note one octave above, and the extra B and E strings are in unison. The pairs of strings are played together as one, so the technique and tuning are the same as a conventional guitar, but they create a much fuller tone, with the additional strings adding a natural chorus effect. They are used almost solely to play harmony and rhythm parts, rather than for guitar solos. They are relatively common in folk rock music. Lead Belly is the folk artist most identified with the twelve-string guitar, usually acoustic with a pickup.

George Harrison of the Beatles and Roger McGuinn of the Byrds brought the electric twelve-string to notability in rock and roll. During the Beatles' first trip to the United States, in February 1964, Harrison received a new 360/12 model guitar from the Rickenbacker company, a twelve-string electric made to look onstage like a six-string. He began using the 360 in the studio on Lennon's "You Can't Do That" and other songs. McGuinn began using electric twelve-string guitars to create the jangly, ringing sound of the Byrds. Both Jimmy Page, the guitarist with Led Zeppelin, and Leo Kottke, a solo artist, are well known as twelve-string guitar players.

Main article: 3rd bridge

The third-bridge guitar is an electric prepared guitar with an additional, third bridge. This can be a normal guitar with, for instance, a screwdriver placed under the strings, or it can be a custom-made instrument. Lee Ranaldo of Sonic Youth plays with a third bridge.

Main article: Double neck guitar A Gibson EDS-1275

Double-neck (or, less commonly, "twin-neck") guitars enable guitarists to play both guitar and bass guitar or, more commonly, both a six-string and a twelve-string. In the mid-1960s, one of the first players to use this type of guitar was Paul Revere & the Raiders' guitarist Drake Levin. Another early user was John McLaughlin. The double-neck guitar was popularized by Jimmy Page, who used a custom-made, cherry-finished Gibson EDS-1275 to perform "Stairway to Heaven", "The Song Remains the Same" and "The Rain Song", although for the recording of "Stairway to Heaven" he used a Fender Telecaster and a Fender XII electric twelve-string. Mike Rutherford of Genesis and Mike + the Mechanics is also famous for his use of a double-neck guitar during live shows. Don Felder of the Eagles used the Gibson EDS-1275 during the Hotel California tour. Muse guitarist and vocalist Matthew Bellamy uses a silver Manson double-neck on his band's Resistance Tour. Rush guitarist Alex Lifeson is also known for using double-neck guitars in the live performance of several songs. In performances of the song "Xanadu" during the band's 2015 R40 anniversary tour, Lifeson played a white Gibson EDS-1275 double-neck guitar with six-string and twelve-string necks, while bassist Geddy Lee performed with a double-neck Rickenbacker guitar with four-string bass and twelve-string guitar necks.

Popular music and rock groups often use the electric guitar in two roles: as a rhythm guitar which provides the chord sequence or "progression" and sets out the "beat" (as part of a rhythm section), and a lead guitar, which is used to perform melody lines, melodic instrumental fill passages, and guitar solos. In some rock or metal bands with two guitarists, the two performers may perform as a guitar tandem, and trade off the lead guitar and rhythm guitar roles. In bands with a single guitarist, the guitarist may switch between these two roles, playing chords to accompany the singer's lyrics, and then playing a guitar solo in the middle of the song.

Gibson Les Paul has been used in many genres, including rock, country, pop, soul, rhythm and blues, blues, jazz, reggae, punk, and heavy metal

In the most commercially available and consumed pop and rock genres, electric guitars tend to dominate their acoustic cousins in both the recording studio and live venues, especially in the "harder" genres such as heavy metal and hard rock. However the acoustic guitar remains a popular choice in country, western and especially bluegrass music, and it is widely used in folk music. Even metal and hard rock guitarists play acoustic guitars for some ballads and for MTV unplugged acoustic performances.

Jazz guitar playing styles include rhythm guitar-style "comping" (accompanying) with jazz chord voicings (and in some cases, walking basslines) and "blowing" (improvising solos) over jazz chord progressions with jazz-style phrasing and ornaments. The accompanying style for electric guitar in most jazz styles differs from the way chordal instruments accompany in many popular styles of music. In rock and pop, the rhythm guitarist usually performs the chords in dense and regular fashion, which sets out the beat of a tune. Rock and pop chord voicings tend to focus on the first, third, and fifth notes of the chord. In contrast, in many modern jazz styles, the guitarist plays much more sparsely, intermingling periodic chords and delicate voicings into pauses in the melody or solo. Jazz chord voicings are usually rootless and emphasize the third and seventh notes of the chord. Jazz chords also often include the 9th, 11th and 13th notes of the chord, which are called "extensions".

When jazz guitar players improvise, they use scales, modes, and arpeggios associated with the chords in a tune's chord progression. Jazz guitarists have to learn how to use scales (whole tone scale, chromatic scale, etc.) to solo over chord progressions. Jazz guitar improvising is not merely the recitation of jazz scales and rapid arpeggios. Jazz guitarists try to imbue their melodic phrasing with the sense of natural breathing and legato phrasing used by horn players such as saxophone players. As well, a jazz guitarists' solo improvisations have to have a rhythmic drive and "time feel" that creates a sense of "swing" and "groove". In addition to the traditional rhythm/comping and lead/blowing roles, some jazz guitarists use the electric instrument to play unaccompanied, combining harmony notes and the melody to form a complete piece of music, like classical guitarists.

Most jazz guitarists play hollow-body instruments, but solid-body guitars are also used. Hollow-body instruments were the first guitars used in jazz in the 1930s and 1940s. During the 1970s jazz fusion era, many jazz guitarists switched to the solid body guitars that dominated the rock world, using powerful guitar amps to get a loud sound.

Electric guitars with acoustic guitars in the background

Until the 1950s, the acoustic, nylon-stringed classical guitar was the only type of guitar favored by classical, or art music composers. In the 1950s a few contemporary classical composers began to use the electric guitar in their compositions. Examples of such works include Luciano Berio's Nones (1954) Karlheinz Stockhausen's Gruppen (1955–57); Donald Erb's String Trio (1966), Morton Feldman's The Possibility of a New Work for Electric Guitar (1966); George Crumb's Songs, Drones, and Refrains of Death (1968); Hans Werner Henze's Versuch über Schweine (1968); Francis Thorne's Sonar Plexus (1968) and Liebesrock (1968–69), Michael Tippett's The Knot Garden (1965–70); Leonard Bernstein's MASS (1971) and Slava! (1977); Louis Andriessen's De Staat (1972–76); Helmut Lachenmann's Fassade, für grosses Orchester (1973, rev. 1987), Valery Gavrilin Anyuta (1982), Steve Reich's Electric Counterpoint (1987), Arvo Pärt's Miserere (1989/92), György Kurtág's Grabstein für Stephan (1989), and countless works composed for the quintet of Ástor Piazzolla. Alfred Schnittke also used electric guitar in several works, like the "Requiem", "Concerto Grosso N°2" and "Symphony N°1".

In the 1970s, 1980s and 1990s, a growing number of composers (many of them composer-performers who had grown up playing the instrument in rock bands) began writing contemporary classical music for the electric guitar. These include Frank Zappa, Shawn Lane, Steven Mackey, Nick Didkovsky, Scott Johnson, Lois V Vierk, Tim Brady, Tristan Murail, and Randall Woolf.

Yngwie Malmsteen released his Concerto Suite for Electric Guitar and Orchestra in 1998, and Steve Vai released a double-live CD entitled Sound Theories, of his work with the Netherlands Metropole Orchestra in June 2007. The American composers Rhys Chatham and Glenn Branca have written "symphonic" works for large ensembles of electric guitars, in some cases numbering up to 100 players, and the instrument is a core member of the Bang on a Can All-Stars (played by Mark Stewart). Still, like many electric and electronic instruments, the electric guitar remains primarily associated with rock and jazz music, rather than with classical compositions and performances.[34]R. Prasanna plays a style of Indian classical music (Carnatic music) on the electric guitar.

In the 21st century, European avant garde composers like Richard Barrett, Fausto Romitelli, Peter Ablinger, Bernhard Lang, Claude Ledoux and Karlheinz Essl have used the electric guitar (together with extended playing techniques) in solo pieces or ensemble works. Probably the most ambitious and perhaps significant work to date is Ingwe (2003–2009) by Georges Lentz (written for Australian guitarist Zane Banks), a 60-minute work for solo electric guitar, exploring that composer's existential struggles and taking the instrument into realms previously unknown in a concert music setting.

In Vietnam, electric guitars are often used as an instrument in cải lương music (traditional southern Vietnamese folk opera), sometimes as a substitute for certain traditional stringed instruments like the Đàn nguyệt (two-stringed lute) when they are not available. Electric guitars used in cải lương are played in finger vibrato (string bending), with no amplifiers or sound effects.

  (Redirected from Telecaster)

The Fender Telecaster, colloquially known as the Tele /ˈtɛli/, is the world's first commercially successful solid-body electric guitar. Its simple yet effective design and revolutionary sound broke ground and set trends in electric guitar manufacturing and popular music. Introduced for national distribution as the Broadcaster in the autumn of 1950, it was the first guitar of its kind manufactured on a substantial scale and has been in continuous production in one form or another since its first incarnation.[1]

The Fender Telecaster was developed by Leo Fender in Fullerton, California in 1950. In the period roughly between 1932 and 1949, several craftsmen and companies experimented with solid-body electric guitars, but none had made a significant impact on the market. Leo Fender's Telecaster was the design that made bolt-on neck, solid body guitars viable in the marketplace.

Fender had an electronics repair shop called Fender's Radio Service where he first repaired, then designed, amplifiers and electromagnetic pickups for musicians — chiefly players of electric semi-acoustic guitars, electric Hawaiian lap steel guitars, and mandolins. Players had been "wiring up" their instruments in search of greater volume and projection since the late 1920s, and electric semi-acoustics (such as the Gibson ES-150) had long been widely available. Tone had never, until then, been the primary reason for a guitarist to go electric, but in 1943, when Fender and his partner, Clayton Orr "Doc" Kauffman, built a crude wooden guitar as a pickup test rig, local country players started asking to borrow it for gigs. It sounded bright and sustaining. Fender was intrigued, and in 1949, when it was long understood that solid construction offered great advantages in electric instruments, but before any commercial solid-body Spanish guitars had caught on (the then-small Audiovox company apparently offered a modern, solid-body electric guitar as early as the mid-1930s), he built a better prototype.

That hand-built prototype, an anonymous white guitar, had most of the features of what would become the Telecaster. It was designed in the spirit of the solid-body Hawaiian guitars manufactured by Rickenbacker — small, simple units made of Bakelite and aluminum with the parts bolted together — but with wooden construction. (Rickenbacker, then spelled "Rickenbacher", also offered a solid Bakelite-bodied electric Spanish guitar in 1935 that seemed to presage details of Fender's design.)

The initial single-pickup production model appeared in 1950, and was called the Fender Esquire. Fewer than fifty guitars were originally produced under that name, and most were replaced under warranty because of early manufacturing problems. In particular, the Esquire necks had no truss rod and many were replaced due to bent necks. Later in 1950, this single-pickup model was discontinued, and a two-pickup model was renamed the Broadcaster. From this point onward all Fender necks incorporated truss rods. The Esquire was reintroduced in 1951 as a single pickup Telecaster, at a lower price.[2][better source needed]

The so-called Nocaster was a short-lived variant of Telecaster. Produced in early to mid-1951, it was the result of legal action from the Gretsch company over the guitar's previous name, the Broadcaster (Gretsch already had the "Broadkaster" name registered for a line of drums). In the interim, before Fender had come up with an alternate name and printed appropriately revised headstock decals, factory workers simply snipped the "Broadcaster" name from its existing stock of decals, so guitars with these decals are identified simply as "Fender", without any model name. By the summer of 1951 the guitar was officially renamed as the Telecaster and has been known as such ever since.

The term Nocaster was originally coined by collectors to denote these transitional guitars that appeared without a model name on the headstock. Since they were manufactured in this form for only a few months very early in the Broadcaster/Telecaster's history, original Nocasters are highly prized and expensive collector's items. There are no official production numbers, but experts estimate that fewer than 500 Nocasters were produced. Fender has since registered Nocaster as a trademark to denote its modern replicas of this famous rarity.

In 1951, Fender released the innovative and musically influential Precision Bass as a similar looking stable-mate to the Telecaster. This body style was later released as the Fender Telecaster Bass in 1968 after the Precision Bass had been changed in 1957 to make it more closely resemble the Fender Stratocaster guitar. At the time Leo Fender began marketing the new, more refined Stratocaster in 1954, he expected it to replace the Telecaster, but the Telecaster's many virtues and unique musical personality have kept it in demand to the present day.

Leo Fender's simple and modular design was geared to mass production and made servicing broken guitars easier. Guitars were not constructed individually, as in traditional luthiery. Rather, components were produced quickly and inexpensively in quantity and assembled into a guitar on an assembly line. The bodies were bandsawn and routed from slabs, rather than hand-carved individually, as with other guitars made at the time, such as Gibsons. Fender did not use the traditional glued-in neck, but rather a "bolt-on" neck (which is actually affixed using screws, not bolts). This not only made production easier, but allowed the neck to be quickly removed and serviced, or replaced entirely. In addition, the classic Telecaster neck was fashioned from a single piece of maple without a separate fingerboard, and the frets were slid directly into the side of the maple surface—a highly unorthodox approach in its day (guitars traditionally featured rosewood or ebony fingerboards glued onto mahogany necks). The electronics were easily accessed for repair or replacement through a removable control plate, a great advantage over the construction of the then-predominant hollow-body instruments, in which the electronics could be accessed only through the soundholes.

In its classic form, the guitar is simply constructed, with the neck and fingerboard comprising a single piece of maple, screwed to an ash or alder body inexpensively jigged with flat surfaces on the front and back. The hardware includes two single coil pickups controlled by a three-way selector switch, and one each of volume and tone controls. The pickguard was first Bakelite, soon thereafter it was celluloid (later other plastics), screwed directly onto the body with five (later eight) screws. The bridge has three adjustable saddles, with strings doubled up on each. In its original design nearly all components are secured using only screws (body, neck, tuners, bridge, scratchplate, pickups to body, control plate, output socket), with glue used to secure the nut and solder used to connect the electronic components. With the introduction of the truss rod, and later a rosewood fingerboard, more gluing was required during construction. The guitar quickly gained a following, and soon other, more established guitar companies (such as Gibson, whose Les Paul model was introduced in 1952, and later Gretsch, Rickenbacker, and others) began working on wooden solid-body production models of their own.

A huge range of aftermarket components are manufactured, including bridges with three vintage-look brass saddles, compensated (by having two separate string separation points on each saddle) to improve intonation. There are also "vertical stack" humbucker pickups which fit into a standard bridge in place of the traditional single-coil units and maintain the original appearance.

The original switch configuration used from 1950 to 1952 allowed selection of neck pickup with treble tone cut in the first position (for a bassier sound), the neck pickup with its natural tone in the second position with no tone, and in the third switch position both pickups together with the neck pickup blended into the bridge, depending on the position of the second "tone" knob. The first knob functioned normally as a master volume control. This configuration did not have a true tone control knob.[3]

In 1952 the pickup selection circuit was modified by Fender to incorporate a real tone control. Between 1953 and 1967 the neck could be selected alone with a pre-set bassy sound and no tone control, in the middle switch the neck could be selected alone with the tone control and finally the bridge could be selected with the tone control. Although this provided the player with a proper tone control, this assembly did away with any sort of pickup combination. Eventually from late 1967 Fender again modified the circuit for the final time to give the Telecaster a more traditional twin pickup switching system: neck pickup alone with tone control in the first position, both pickups together with the tone control in the middle position and in the third position the bridge pickup alone with the tone control.[3]

Typical modern Telecasters (such as the American Standard version) incorporate several details different from the classic form. They typically feature 22 frets (rather than 21) and truss rod adjustment is made at the headstock end, rather than the body end, which had required removal of the neck on the original (the Custom Shop Bajo Sexto Baritone Tele was the only Telecaster featuring a two-octave 24-fret neck). The three-saddle bridge of the original has been replaced with a six-saddle version, allowing independent length and height adjustment for each string. The long saddle bridge screws allow a wide range of saddle bridge positions for intonation tuning. The stamped metal bridge plate has been replaced with a flat plate, and the removable chromed bridge cover (often called the "ashtray" for its secondary use) has been discontinued for most models; it improved shielding but prevented players from muting strings at the bridge and made it impossible to pick near the saddles to produce the characteristic Telecaster 'twang'.

During the CBS era in the 1970s, the Telecaster body style was changed to a new "notchless" shape, having a less pronounced notch in the crook where the upper bout meets the neck. The notchless body style was discontinued in 1982.

The short-lived Elite Telecaster of 1983 incorporated two specially designed humbucking pickups powered by an active circuitry that featured a "TBX" guitar expander and an MDX midrange booster with 12 dB of gain. Other features included a "Freeflyte" hardtail bridge and die-cast tuning machines with pearloid buttons. This guitar was among the latest CBS-era Fenders to feature a BiFlex truss-rod system, low-friction EasyGlider string trees and active electronics. After CBS sold Fender to a group of employees led by Bill C. Schultz in 1985, production ceased on the Elite Telecaster and other Elite models. Fender Japan made its own version of the Elite Telecaster in late 1984, which featured a 22-fret neck with medium-jumbo fretwire and a modern 9.5 inch fingerboard radius. Notable Elite Telecaster players include Johnny Hallyday, Dave Davies of The Kinks, Michael Houser with Widespread Panic, and Andy Summers of The Police.[citation needed]

The Telecaster is known for its ability to produce both a bright, rich cutting tone (the typical Telecaster country twang) and a mellow, warm, bluesy jazz tone depending on the selected pickup, respectively "bridge" pickup or "neck" pickup, and by adjusting the tone control. The bridge pickup has more windings than the neck pickup, hence producing higher output, which compensates for a lower amplitude of vibration of the strings at bridge position. At the same time, a capacitor between the slider of the volume control and the output allows treble sounds to bleed through while damping mid and lower ranges.[4] Slanting the bridge pickup also increased the guitar's treble response. The solid body allows the guitar to deliver a clear and sustaining amplified version of the strings' sound; this was an improvement over previous electric guitar designs, whose resonant hollow bodies made them prone to unwanted acoustic feedback when volume was increased. These design elements intentionally allowed guitarists to emulate steel guitar sounds, as well as "cut-through" and be heard in roadhouse Honky-Tonk and big Western Swing bands, initially making this guitar particularly useful in country music. Its wide range of tonalities allows the Telecaster to be used successfully for many styles of music including country, pop, rock, blues and jazz.

The Telecaster has also been a longtime favorite guitar for hot-rod customizing. Several variants of the guitar appeared throughout the years with a wide assortment of pickup configurations, such as a humbucker in the neck position, three single-coil pickups and even dual humbuckers with special wiring schemes. Fender offered hot-rodded Teles with such pickup configurations, the US Fat and Nashville B-Bender Telecasters around 1998. The Deluxe Blackout Tele was also equipped with three single-coil pickups, a "Strat-o-Tele" selector switch and a smaller headstock than a standard Telecaster. The most common variants of the standard two-pickup solid body Telecaster are the semi-hollow Thinline, the Custom, -which replaced the neck single coil-pickup with a humbucking pickup, and the twin-humbucker Deluxe. The Custom and Deluxe were introduced during the CBS period and reissues of both designs are currently offered.

Designed by German luthier Roger Rossmeisl, the Telecaster Thinline model first appeared in 1968/69. It is characterized by a body having a solid center core with hollow wings to reduce weight. The '69 version has two standard Telecaster single-coil pickups, string-through-body bridge, and a choice of an ash or mahogany body. Later a '72 version was introduced based on the Fender Telecaster Deluxe with two Fender Wide Range humbucking pickups. In 2011, Fender released the Modern Player Telecaster Thinline as a part of the Modern Player series. This guitar features two MP-90 pickups, similar to the Gibson P-90 and a mahogany body. The Fender Custom Shop has produced a variation referred to as the "50's Telecaster Thinline" with an ash body, maple neck and a Twisted Tele neck pickup matched with a Nocaster bridge pickup.

Main article: Fender Telecaster Custom

The first edition of the Telecaster Custom was produced between 1959-1968, and featured a double-bound body but otherwise-standard configuration. While the guitar was known as the Telecaster Custom, the decal on the headstock read "Custom Telecaster". Later editions of the Tele Custom were popularized by Rolling Stones' guitarist and composer Keith Richards, featuring a Fender Wide Range humbucker in the neck position and a single-coil pickup in the bridge. To distinguish this model from the mid-1960s Custom with body binding, the market generally refers to the guitar as the "1972 Custom", indicating the year this model was originally released.

Main article: Fender Telecaster Deluxe

This model includes two Fender Wide Range humbucking pickups and was originally produced from 1972 to 1981 and has since then been reissued. The Tele Deluxe sported a large headstock similar to the Stratocaster, maple neck and a contoured body, as well as a tremolo bridge option on models manufactured after 1973/74.

Main article: Fender Telecaster Plus

Designed to restore Fender's reputation after a group of employees led by William C. Schultz took over ownership from CBS in the early 1980s. The pickups used in early models were dual humbucking Red Lace Sensors in the bridge position and a single Blue Lace Sensor in the neck position. Later models (post-1995 or so) used three Gold Lace Sensors or a Red/Silver/Blue set in a Strat-like configuration, as well as low-friction roller nuts, locking synchronized vibrato bridge and tuners, and a bound contoured alder body with ash veneers. These instruments were discontinued in 1998 with the advent of the American Deluxe series. In 2011 Fender released the Modern Player Telecaster Plus as a part of the Modern Player series. The guitar has a humbucker in the bridge, a Strat pickup in the middle, and a Tele pickup in the neck positions.

Main article: Fender Tele Jr.

The Fender Tele Jr. is a variant of the Fender Telecaster electric guitar that the Fender Custom Shop produced in a limited run of 100 units in the early 1990s. It uses a Telecaster body shape, scale length, and electronics controls (albeit, with a reversed control plate). However, many of its construction and electronic features—for example its set-in neck and P-90-style pickups—are similar to those of a Gibson Les Paul Junior and Gibson Les Paul Special electric guitars.

Main article: Fender J5 Telecaster

The Triple Tele Deluxe is Marilyn Manson and Rob Zombie guitarist John 5's signature model. It is similar to the regular Telecaster Deluxe, but it features three Fender "Enforcer" humbuckers and a chrome pickguard.

Main article: Fender Cabronita

The Cabronita (and Custom Shop variant La Cabronita) is a model that is distinguished by the use of Fidelitron or the more expensive TV Jones Classic humbucking pickups, which are identical in size and use the same basic design as the original Gretsch humbuckers. The La Cabronita is an American-made, custom-built-to-order instrument. It typically has one TV Jones Classic pickup in the bridge position although being custom built, in can be ordered in any configuration. All Cabronitas can be distinguished by use of a smaller pickguard that covers the lower horn only, similar to the pickguard used in the original prototype for the Telecaster in 1949.

The versions built in Mexico offered either a solid body or Thinline body, with both featuring two Fender Fidelitron pickups, a volume knob and pickup selector. They both have maple necks, 25.5" scale, a 9.5 inch radius fretboard, "Medium C" profile and 1 5/8" nut width, common to many standard Telecasters made in Mexico, although the Cabronita comes with 22 frets instead of the more common 21. For a brief period, Fender offered an American made "Telebration Cabronita" that used two of the TV Jones pickups.

While "Cabronita" isn't a proper Spanish word, it roughly translates to English as "little bastard"[5] or "little devil".

Main article: Fender Modern Player Telecaster

The Modern Player Telecaster is offered in two distinct styles: a Plus model and a Thinline model. The Plus utilizes a pine body, a standard Telecaster pickup in the neck position, a reverse wound single-coil strat-pickup in the middle position and a humbucker in the bridge position. It is equipped with coil tapping and a five way switch to provide seven different pickup combinations.

The MP Thinline adopts a pickguard similar to Deluxe models and a Stratocaster style bridge, without tremolo. It features a mahogany body, two P-90 style single-coil pickups, individual volume and tone controls and the three-way pickup selector in the upper horn position.

Both use the standard 25.5" scale on a 22 fret maple necks that are unlike any other Telecasters in that they do not utilize an overhang to accomplish the 22nd fret, but instead use a longer, square ended neck that is not fully compatible with previous Fender parts. They are manufactured in China and at the time of their introduction, represented the least expensive Telecasters under the Fender brand.

In keeping with other models Fender distinguishes product lines manufactured in different locations.

The American Deluxe Telecaster (introduced in 1998; upgraded in 2004, 2008, and 2010) features a pair of Samarium Cobalt Noiseless pickups and the S-1 switching system. Models made prior to 2004 featured two Fender Vintage Noiseless Tele single-coils, Fender/Fishman Powerbridge piezo system and four-bolt neck fixing. Other refinements include a bound contoured alder or ash body and an abalone dot-inlaid maple neck with rosewood or maple fingerboard, 22 medium-jumbo frets, rolled fingerboard edges, and highly detailed nut and fret work. The HH model sported an ebony fingerboard, quilted or flamed maple top and a pair of Enforcer humbuckers with S-1 switching (discontinued as of 2008). As of March 23, 2010, Fender updated the American Deluxe Telecaster with a compound radius maple neck, N3 Noiseless Tele pickups and a reconfigured S-1 switching system for wider sonic possibilities. The new model now sports staggered, locking tuning machines, which provide a better break angle over the nut for increased sustain and improved tuning stability. The Thinline version has been introduced in 2013. Fender discontinued the American Deluxe series in 2016.

The American Series model used two single-coil pickups with DeltaTone system (featuring a high output bridge pickup and a reverse-wound neck pickup). Other features included a parchment pickguard, non-veneered alder or ash bodies and rolled fingerboard edges.

In 2003 Fender offered Telecasters with a humbucking/single coil pickup arrangement or two humbucking pickups featuring Enforcer humbucking pickups, and S-1 switching. These models were discontinued in 2007. As of 2008, all American Standard Telecasters came with a redesigned Tele bridge with vintage-style bent steel saddles. In March 2012 the American Standard Telecaster was updated with Custom Shop pickups (Broadcaster in the bridge, Twisted in the neck); the body is now contoured for reduced weight and more comfort. In 2014 the American Standard Telecaster HH was introduced, sporting a pair of Twin Head Vintage humbucking pickups (open-coil with black bobbins in the bridge, metal-covered in the neck). Controls include a dual concentric volume pot for each pickup, a master tone and 3-way pickup switching.

The American Nashville B-Bender guitar is modeled after the personally customized instruments of some of Nashville's top players, featuring a Fender/Parsons/Green B-Bender system, two American Tele single-coils (neck, bridge), a Texas Special Strat single-coil (middle) and five-way "Strat-O-Tele" pickup switching. Ideal for country bends and steel guitar glisses, this Tele is available only with a maple fingerboard.

The American Series Ash Telecaster is based on the '52 vintage reissue. It features an ash body, one-piece maple neck/fingerboard with 22 frets and two Modern Vintage Tele single-coil pickups. Fender discontinued this guitar in 2006.

The Custom Classic Telecaster was the Custom Shop version of the American Series Tele, featuring a pair of Classic and Twisted single-coils in the bridge and neck positions, as well as a reverse control plate. Earlier versions made before 2003 featured an American Tele single-coil paired with two Texas Special Strat pickups and 5-way switching. Discontinued in 2009 and replaced by the Custom Deluxe Telecaster series models. The 2011 version of the Custom Shop "Custom Deluxe" Telecaster featured a lightweight Ash body with contoured heel, Birdseye maple neck, and a pickup set that included a Twisted Tele neck pickup and a Seymour Duncan Custom Shop BG-1400 stacked humbucker in the bridge position.

The Highway One Telecaster (introduced in 2000) featured a pair of distortion-friendly alnico III single-coil pickups, super-sized frets, Greasebucket circuit, satin nitrocellulose finish, and 1970s styling (since 2006). The Highway One Texas Telecaster sported a one-piece maple neck/fretboard with a modern 12" radius and 22 jumbo frets, solid ash body and a pair of Hot Vintage alnico V pickups.

In 2010, the American Special Telecaster was introduced. While retaining such features from the Highway One as jumbo frets, Greasebucket tone circuit and 1970s logo, the American Special also includes some upgrades such as a glossy urethane finish, compensated brass 3-saddle bridge and Highway One Texas Tele pickups (alnico V). In the Fall of 2013, Fender upgraded the pickups on the American Special line to Custom Shop Texas Special pickups.

Artist Series Telecasters have features favored by world-famous Fender endorsees James Burton, John 5, Muddy Waters, Jim Root, G. E. Smith, Joe Strummer and Jim Adkins. Custom Artist models are made at the Fender Custom Shop, differing slightly quality and construction-wise; their prices are much higher than the standard production versions.

In September 2010, Fender introduced the Mexican-made Black Top Telecaster HH, featuring dual hot vintage alnico humbucking pickups, a one-piece maple neck with rosewood or maple fretboard and 22 medium-jumbo frets. Other features include a solid contoured alder body, a reversed control assembly and black skirted amp control knobs.

In 2011, Fender released the Modern Player series, which featured the Modern Player Telecaster Thinline and the Modern Player Telecaster Plus.

Squier model Telecasters are sold by Squier, a Fender-owned import brand. These can bear the Telecaster name, since Squier is owned by Fender. Squier guitars, especially the Telecasters, have gained popularity[citation needed] and a good reputation amongst guitar players, since it has expanded its production of guitar models. Squier has a wide range of different Telecaster-type guitars available, from the entry-level Affinity Series to the better quality Standard and Classic Vibe Series. Also available are the Artist Series and Vintage Modified Series. Among other famous musicians, Sheryl Crow has occasionally used a Squier Telecaster for recordings and live performances.[6]

The Telecaster was important in the evolution of country, electric blues, funk, rock and roll, and other forms of popular music. Its solid construction let guitarists play loudly as a lead instrument, with long sustain if desired. It produced less of the uncontrolled, whistling, 'hard' feedback ('microphonic feedback') that hollowbodied instruments tend to produce at volume (different from the controllable feedback later explored by Pete Townshend and countless other players). Even though the Telecaster is more than half a century old, and more sophisticated designs have appeared since the early 1950s (including Fender's own Stratocaster), the Telecaster remains in production. There have been numerous variations and modifications, but a model with something close to the original features has always been available. In a recent article for Music Aficionado, Alex Lifeson of Rush wrote "I bought a reissue 1959 Telecaster back in 1981, and that guitar has since become my primary writing guitar for all of these years, especially for the electric work. Every time I pick it up, it feels like an old friend. I took all of the finish off of the neck, so it’s raw wood, and I feel very connected to it when I’m playing it. That is my number-one “go to” for writing new music."

Bass guitar

Mesa-Boogie "Mark IV", a guitar combo amplifier

A guitar amplifier (or guitar amp) is an electronic amplifier that strengthens the weak electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet. A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier (and preamplifier) circuits, requiring the use of a separate speaker cabinet–or it may be a "combo" amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet. There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight "practice amplifiers" with a single 8" speaker to heavy combo amps with four 10" speakers and a powerful amplifier, which are loud enough to use in a nightclub or bar performance.

Guitar amplifiers can also modify the instrument's tone by emphasizing or de-emphasizing certain frequencies, using equalizer controls, which function the same way as the bass and treble knobs on a home hi-fi stereo, and by adding electronic effects; distortion (also called "overdrive") and reverb are commonly available as built-in features. The input of modern guitar amplifiers is a 1/4" jack, which is fed a signal from an electro-magnetic pickup (from an electric guitar) or a piezoelectric pickup (usually from an acoustic guitar) using a patch cord, or a wireless transmitter. For electric guitar players, their choice of guitar amp and the settings they use on the amplifier are a key part of their signature tone or sound. Some guitar players are longtime users of a specific amp brand or model. Many electric guitar players use external effects pedals to alter the sound of their tone before the signal reaches the guitar amp, such as the wah wah pedal and the chorus pedal.

This article focuses on electric guitar amps. For information on amps for bass guitar, a lower-pitched, similar instrument, see the article on bass amps.

A Fender Bassman amp head with a 15" speaker cabinet.

Typically, guitar amplifiers have two amplifying circuit stages and in addition frequently have tone-shaping electric circuits, which usually include at least bass and treble controls, which function similarly to the equivalent controls on a home hi-fi system. More expensive amplifiers typically have more controls for other frequency ranges, such as one or two "midrange" controls and a "presence" control for very high frequencies. Some guitar amplifiers have a graphic equalizer, which uses vertical fader controls which can control many frequency bands. The first amplifier stage is a preamplifier stage (there may be more than one), which amplifies the guitar signal to a level that can drive the power stage. The power amplifier or output stage produces a high current signal to drive a loudspeaker to produce sound that the guitarist and audience can hear.

There may be one or more tone stages that affect the character of the guitar signal:

Tone stages may also provide electronic effects—such as equalization, compression, distortion, chorus, or reverb. Amplifiers may use vacuum tubes (called valves in Britain), solid-state (transistor) devices, or both.

There are two configurations of guitar amplifiers: combination ("combo") amplifiers, which include an amplifier and one or more speakers in a wooden cabinet, and the standalone amplifier (often called a "head" or "amp head"), which does not include a speaker, but passes the amplified signal via a speaker cable to one or more external speaker cabinets. A wide range of speaker configurations are available in guitar cabinets, ranging from cabinets with a single speaker (e.g., 1×10" or 1×12") or multiple speakers (e.g., 2×10", 4×10" or 8x10"). Guitar amplifiers have a wide range in price and quality. Music equipment companies import small, low-powered practice amplifiers for students and beginners that sell for less than $50 USD. Other companies produce expensive custom-made amplifiers for professional musicians, which can cost thousands of dollars. Most combo amplifiers have a carrying handle, and many combo amplifiers and cabinets have metal or plastic-reinforced corners to protect the amp during transportation.

Control knobs are typically mounted on the front of the cabinet or chassis, though in some cases, the knobs are on a recessed panel at the back of the top of the amplifier. The most basic amps only have a few knobs, which typically control volume, bass and treble. More expensive amps may have a number of knobs that control pre-amp volume (or "gain"), distortion or overdrive, volume, bass, mid and treble, and reverb. Some older amps (and their re-issued versions) have a knob that controls a vibrato effect. The 1/4" input jack is typically mounted on the front of the amplifier. In the simplest, least expensive amplifiers, this 1/4" jack is the only jack on the amplifier. More expensive amplifiers may have a patch bay for multiple inputs and outputs, such as a pre-amp out (for sending to another guitar amplifier), an in jack to create an effects loop (when used with the pre-amp out jack), an external speaker output (for powering an additional speaker cabinet), and stereo RCA jacks or an 1/8" jack, for connecting a CD player or MP3 player so that a player can practice along with recorded music. Some amps have a 1/4" jack for connecting a pedal to turn the amp's onboard overdrive and reverb on and off or to switch between channels. The vast majority of guitar amps can only be powered by AC mains power (plugging into a wall outlet); however, a small number of practice amps designed for buskers also have battery power, enabling them to be used for street performances.

A 1940s-era Valvo combo amp. Fender Deluxe 1953

In the 1920s, it was very hard for a musician playing a pickup-equipped guitar to find an amplifier and speaker to make their instrument louder as the only speakers that could be bought were "radio horns of limited frequency range and low acoustic output". The cone speaker, widely used in 2000s-era amp cabinets, was not offered for sale until 1925. The first amplifiers and speakers could only be powered with large batteries, which made them heavy and hard to carry around. When engineers developed the first AC mains-powered amplifiers, they were soon used to make musical instruments louder. Engineers invented the first loud, powerful amplifier and speaker systems for public address systems and movie theaters. These large PA systems and movie theatre sound systems were very large and very expensive, and so they could not be used by most touring musicians. After 1927, smaller, portable AC mains-powered PA systems that could be plugged into a regular wall socket "quickly became popular with musicians"; indeed, "...Leon McAuliffe (with Bob Wills) still used a carbon mic and a portable PA as late as 1935." During the late 1920s to mid-1930s, small portable PA systems and guitar combo amplifiers were fairly similar. These early amps had a "single volume control and one or two input jacks, field coil speakers" and thin wooden cabinets; remarkably, these early amps did not have tone controls or even an on-off switch.[1]

In 1928, the Stromberg-Voisinet firm was the first company to sell an electric stringed instrument and amplifier package. However, musicians found that the amps had an "unsatisfactory tone and volume, [and] dependability problems", so the product did not sell well. Even though the Stromberg-Voisinet amp did not sell well, it still launched a new idea: a portable electric instrument amp with a speaker, all in an easily transported wooden cabinet. In 1929, Vega electrics launched a portable banjo amplifier. In 1932, Electro String Instruments and amplifier (this is not the same company asStromberg Electro Instruments) introduced a guitar amp with "high output" and a "string driven magnetic pickup". Electro set out the standard template for combo amps: a wooden cabinet with the electronic amplifier mounted inside, and a convenient carrying handle to facilitate transporting the cabinet. 1n 1933, Vivi-Tone amp set-ups were used for live performances and radio shows. In 1934, Rickenbacker launched a similar combo amp which added the feature of metal corner protectors, which keep the corners in good condition during transportation.[1]

In 1933, Dobro released an electric guitar and amp package. The combo amp had "two 8″ Lansing speakers and a five-tube chassis. Dobro made a two speaker combo amp that was on the market over 12 years before Fender launched its two-speaker "Dual Professional/Super" combo amp. In 1933, Audio-Vox was founded by Paul Tutmarc, the inventor of the first electric bass (Tutmarc's instrument did not achieve market success until Leo Fender's launched the Precision Bass). In 1933, Vega sold a "pickup and amplifier set" which a musician could use with her/his existing guitar. In that same year, the Los Angeles-based Volu-Tone company also sold a pickup/amplifier set. Volu-Tone used "high voltage current" to sense the string vibration, a potentially dangerous approach that did not become popular. In 1934 Dobro released a guitar amp with a vacuum tube rectifier and two power tubes. By 1935, Dobro and National began selling combo amps for Hawaiian guitar. In 1934, Gibson developed prototype combo amps, but these never got produced and sold. By 1935, Electro/Rickenbacher sold "more amps and electric guitars than all the amps and electrified/electric guitars made from ’[19]28 through the end of ’[19]34, combined."[1]

The first electric instrument amplifiers were not designed for use with electric guitars. The earliest examples were portable PA systems, which appeared in the early 1930s when the introduction of electrolytic capacitors and rectifier tubes allowed the production of economical built-in power supplies that could be plugged into wall sockets, instead of heavy multiple battery packs, since rechargeable batteries would not become lightweight until many decades later. While guitar amplifiers from the beginning were used to amplify acoustic guitar, electronic amplification of guitar was first widely popularized by the 1930s and 1940s craze for Hawaiian music, which extensively employed the amplified lap steel Hawaiian guitar.[2]

In the 1920s, the earliest combo amplifiers did not have any tone controls. Tone controls on early guitar amplifiers were very simple and provided a great deal of treble boost, but the limited controls, the loudspeakers used, and the low power of the amplifiers (typically 15 watts or less prior to the mid-1950s) gave poor high treble and bass output. Some models also provided effects such as an electronic tremolo unit. Early Fender amps labeled tremolo as "vibrato" and labeled the vibrato arm of the Stratocaster guitar as a "tremolo bar" (see vibrato unit, electric guitar, and tremolo). Some later models included an onboard spring reverb effect, one of the first being the Ampeg Reverberocket amp.

Gibson Lancer GA-35 (mid-1960s) guitar amplifier

In the 1950s, several guitarists experimented with distortion produced by deliberately overdriving their amplifiers, including Goree Carter,[3]Joe Hill Louis,[4][5]Elmore James,[6]Ike Turner,[7]Willie Johnson,[8]Pat Hare,[9]Guitar Slim,[10]Chuck Berry,[11]Johnny Burnette,[8] and Link Wray.[12] In the early 1960s, surf rock guitarist Dick Dale worked closely with Fender to produce custom made amplifiers,[13] including the first 100-watt guitar amplifier.[14] He pushed the limits of electric amplification technology, helping to develop new equipment that was capable of producing "thick, clearly defined tones" at "previously undreamed-of volumes."[13]

U2 guitarist The Edge's 1964 Vox AC30 combo amp.

Distortion became more popular from the mid-1960s, when The Kinks guitarist Dave Davies produced distortion effects by connecting the already distorted output of one amplifier into the input of another. Later, most guitar amps were provided with preamplifier distortion controls, and "fuzz boxes" and other effects units were engineered to safely and reliably produce these sounds. In the 2000s, overdrive and distortion has become an integral part of many styles of electric guitar playing, ranging from blues rock to heavy metal and hardcore punk.

Guitar combo amplifiers were at first used with bass guitars and electric pianos, but these instruments produce a wider frequency range and need a full-range speaker system. Much more amplifier power is required to reproduce low-frequency sound, especially at high volume. Reproducing low frequencies also requires a suitable woofer or subwoofer speaker and enclosure. Woofer enclosures must be larger and more sturdily built than cabinets for mid-range or high-frequency (tweeter) speakers. As such, in the 1950s, when Ampeg introduced bass amplifier and speaker systems, these began to be used by bass guitarists. Similarly, Hammond organ players used a specialized keyboard combo amplifier, the Leslie speaker cabinet, which contains a woofer for the low frequencies and a horn for the high frequencies. The Leslie horns rotated and a baffle around the woofer rotated as well, producing a chorus effect.

Kustom 200 bass amp – amp head and speakers, 100 watts RMS, two channels, two 15" speakers, 1971

Guitar amplifiers are manufactured in two main forms: a "combo" contains the amplifier and one or more speaker(s) in a single wooden speaker enclosure. A separate configuration is available as well, with a separate amplifier (the "head") on top of one or more cabinets, each of which contains one or more speakers. Another alternative device used for guitar are public address amplifiers. Grunge guitarist Kurt Cobain used four 800 watt PA amplifiers for his early guitar set-up.

Besides one or more instrument inputs (typically a 1/4" jack), other jacks may also be provided, such as an auxiliary input jack (sometimes with its own level control, for a drum machine), "send" and "return" jacks to create an effects loop, an extension speaker jack. Practice amps may have stereo RCA or mini jacks for connecting a CD player, portable media player or other sound source and a 1/4" headphone jack. Some guitar amps have an XLR input so that a microphone can be plugged in for singing. Guitar amps that include a mic input are in effect small, portable PA systems.

A wide range of instrument amplifiers is available at a wide range of price, quality, and performance levels. Some amplifiers are designed for beginners, such as small, low-wattage "practice amplifiers", which typically have a single 8" speaker and about 10 watts, or smaller "combo" amps with relatively low wattage (15 to 20 watts) and a single 10" speaker. Mid- to large-size "combo" amps with 30 to 50 watts and one 12" speaker or four 10" speakers are designed for use in band rehearsals and onstage performances. Some guitar amps are designed for specific instruments or particular genres, such as the Marshall amps, which are widely used in heavy metal music.

Vacuum tubes (called "valves" in British English) were by far the dominant active electronic components in most instrument amplifier applications until the 1970s, when solid-state semiconductors (transistors) started taking over. Transistor amplifiers are less expensive to build and maintain, reduce the weight and heat of an amplifier, and tend to be more reliable and more shock-resistant. Tubes are fragile and they need to be replaced and maintained periodically. As well, serious problems with the tubes can render an amplifier inoperable until the issue is resolved. In the 2000s, high-end tube instrument amplifiers (along with a small number of hi-fi power amplifiers used by audiophiles and high-end studio microphone preamplifiers) survive as the few exceptions, because of their perceived sound quality. Tube enthusiasts believe that tube amps produce a "warmer" sound and a more natural "overdrive" sound. Typically, tube amps use one or more dual triodes in the preamplifier section to provide sufficient voltage gain to offset tone control losses and drive the power amplifier section. While tube technology is, in many ways, outdated, tube amps remain popular since many guitarists prefer their sound.[15]

Since the 1980s, most inexpensive and mid-priced guitar amplifiers are based on semiconductor (solid-state) circuits. Some designs incorporate tubes in the preamp stage for their subjectively warmer overdrive sound—see "Hybrid amplifiers", below. Solid-state amplifiers are much cheaper to produce and more reliable, and they are usually much lighter than tube amplifiers.[15] High-end solid-state amplifiers are less common, since many professional guitarists tend to favor vacuum tubes. Some jazz guitarists, however, tend to favor the "cleaner" sound of solid-state amplifiers; only a few solid-state amps have enduring attraction, such as the Roland Jazz Chorus.[15][16][17] Solid-state amplifiers vary in output power, functionality, size, price, and sound quality in a wide range, from practice amplifiers to combos suitable for gigging to professional models intended for session musicians who do studio recording work.

A hybrid amplifier involves one of two combinations of tube and solid-state amplification. It may have a tube power amp fed by a solid-state pre-amp circuit, as in most of the original MusicMan Amps, later amplifier models from Alamo Electronics, the Fender Super Champ XD, and the Roland Bolt amplifier. Randall Amplifiers V2 and T2 use hybrid amp technology. Alternatively, a tube pre-amp can feed a solid-state output stage, as in models from Kustom, Hartke, SWR and Vox. This approach dispenses with the need for an output transformer and easily achieves modern power levels.[15]

Microprocessor technology allows the use of digital onboard effects in guitar amps to create numerous different sounds and tones that simulate the sound of a range of tube amplifiers and different sized speaker cabinets, all using the same amplifier and speaker. These are known as modeling amplifiers, and can be programmed with simulated characteristic tones of different existing amplifier models (and speaker cabinets—even microphone type or placement), or dialed in to the user's taste. Many amps of this type are also programmable by way of USB connection to a home computer or laptop.[15]Line 6 is generally credited with bringing modeling amplification to the market.[18][19] Modeling amplifiers and stompbox pedals, rackmount units and software programs which provide amplifier, speaker cabinet and mic modeling can give a guitarist with the single modeling amp or unit access to a large number of sounds and tones, such as the simulated sound of tube amplifiers, vintage combo amplifiers, huge 8x10" stacks, without having to bring all of this heavy equipment to the studio or stage.

The use of "Full Range Flat Response" (FRFR) amplification systems by electric guitarists has received an extra impetus from modeling amplifiers. Before the widespread availability of modeling amplifiers and units, an electric guitarist would not be able to plug her/his electric guitar straight into a PA system or powered speaker, because in most rock genres, the tonal coloration that a regular guitar amp's preamplifier, equalization filters, power amp, guitar speaker and cabinet design (e.g., 8x10" cabinet) are an essential part of a guitarist's unique tone. The basic concept of FRFR is that the tone is shaped by sound processors placed in the signal chain before the amplifier/speaker stage. However, instead of a guitar amplifier, with its particular sound-shaping characteristics (e.g., many amps roll off high treble frequencies and many amplifiers add frequency coloration), a flat-frequency response amplification systems can be used, such as amplified speakers or a PA system (full-range speakers),[20] or dedicated combo-style amplifiers with a broad frequency range.[21] Such processors can be traditional guitar effects, a modeling amplifier (without power amplifier), or a computer running tone-shaping software.[20] With an amp modeling pedal or unit, a guitarist could even use a flat-response keyboard amplifier combo amp to produce overdriven, vintage tones and sounds.

These amplifiers are intended for acoustic guitars, especially for the way these instruments are used in relatively quiet genres such as folk and bluegrass. They are similar in many ways to keyboard amplifiers, in that they have a relatively flat frequency response, and are usually designed so that neither power amplifier nor speakers add coloration. To produce this relatively "clean" sound, these amplifiers often have very powerful amplifiers (providing up to 800 watts RMS), to provide additional "Headroom" and prevent unwanted distortion. Since an 800 watt amplifier built with standard Class AB technology would be very heavy, some acoustic amplifier manufacturers use lightweight Class D amplifiers, which are also called "switching amplifiers."

Acoustic amplifiers are designed to produce a "clean", transparent, "acoustic" sound when used with acoustic instruments with built-in transducer pickups and/or microphones. The amplifiers often come with a simple mixer, so that the signals from a pickup and condenser microphone can be blended. Since the early 2000s, it has become increasingly common for acoustic amplifiers to provide a range of digital effects, such as reverb and compression. As well, these amplifiers often contain feedback-suppressing devices, such as notch filters or parametric equalizers.[22]

Metal guitarist Klaus Eichstadt in front of his Marshall stack. A 3×6 stack of mock Marshall guitar cabinets for Jeff Hanneman of Slayer

An amplifier stack consists of an amplifier head atop a speaker cabinet—a head on top of one cabinet is commonly called a half stack, a head atop two cabinets a full stack. The cabinet that the head sits on often has an angled top in front, while the lower cabinet of a full stack has a straight front. The first version of the Marshall stack was an amp head on an 8×12 cabinet, meaning a single speaker cabinet containing eight 12" guitar speakers. After six of these cabinets were made, the cabinet arrangement was changed to an amp head on two 4×12 cabinets, meaning four 12" speakers, to enable the cabinets to be more transportable. Some touring metal and rock bands have used a large array of guitar speaker cabinets for their impressive appearance. Some of these arrangements include only the fronts of speaker cabinets mounted on a large frame.[23]

There are many varieties of speaker combinations used in guitar speaker cabinets, including one 12" speaker, one 15" speaker (this is more common for bass amplifiers than for electric guitar cabinets), two 10" speakers, four 10" speakers, four 12" speakers, or eight 10" speakers. Less commonly, guitar cabinets may contain different sizes of speaker in the same cabinet. Cabinets with eight 10" speakers are large and heavy, and they are often equipped with wheels and a "towel bar"-style handle for transport. Some cabinets use mixed speaker types, such as one 15" speaker and two 10" speakers.

Combo guitar amplifier cabinets and guitar speaker cabinets use several different designs, including the "open back" cabinet, the closed back cabinet (a sealed box), and, less commonly, bass reflex designs which use a closed back along with a vent or port cut into the cabinet.[24] With guitar amps, most "open back" amp cabinets are not fully open; in fact, part of the back is enclosed with panels. Combo guitar amp cabinets and standalone speaker cabinets are often made of plywood; "[d]ecent...cabs have even been constructed from MDF and particle board—although these are typically considered low-budget options."[24] In a cabinet, "...the size and depth of the cabinet, the type of wood used to build it, the way that wood is fixed together, the type and thickness of the baffle material (the sheet of wood to which the speaker is mounted), and the way this baffle is mounted to the cab" all affect the sound and tone of the cabinet.[24]

When two or more speakers are used in the same cabinet, or when two cabinets are used together, the speakers can be wired in parallel or in series, or in a combination of the two (e.g., two 2x10" cabinets, with the two speakers wired in series, can be connected together in parallel). Whether speakers are wired in parallel or in series affects the impedance of the system. Two 8 ohm speakers wired in parallel will have a 4 ohm impedance. Guitarists who are connecting multiple cabinets to their amplifier need to consider the minimum impedance of their amplifier. Whether speakers are wired in parallel or in series also affects the tone and sound. When speakers are wired in parallel, this "...dampen[s] and restrain[s]" the speakers, giving a "tighter response, and a smoother breakup"; speakers that are wired in "...series (usually no more than two) run a little looser, giving a slightly more raw, open and edgy sound."[24]

For electric guitar amplifiers, there is often a distinction between "practice" or "recording studio" guitar amps, which tend to have output power ratings of less than one watt to 20 watts and "performance" or "stage" amps, which are generally 30 watts or higher. Traditionally, these have been fixed-power amplifiers, with some models having a half-power switch to slightly reduce the listening volume while preserving power-tube distortion.

The relationship between perceived volume and power output in watts is not immediately obvious. While beginners sometimes assume that there is a linear relationship between perceived volume and wattage (e.g., they assume that a 5-watt amp will be much quieter at its maximum output than a 50-watt amp), in fact the human ear perceives a 5-watt amplifier as half as loud as a 50-watt amplifier (a tenfold increase in power), and a half-watt amplifier is a quarter as loud as a 50-watt amp. Doubling the power of an amplifier results in a "just noticeable" increase in volume, so a 100-watt amplifier is only just noticeably louder than a 50-watt amplifier. Such generalizations are also subject to the human ear's tendency to behave as a natural compressor at high volumes.

Power attenuation can be used with either low-power or high-power amplifiers, resulting in variable-power amplifiers. A high-power amplifier with power attenuation can produce power-tube distortion through a range of listening volumes, but with a decrease in high power distortion. Other technologies, such as dual rectifiers and the Sag Circuit—which should not be confused with attenuation—allow high power amplifiers to produce low power volume while preserving high power distortion.[25]

Speaker efficiency is also a major factor affecting a tube amplifier's maximum volume. For bass instruments, higher-power amplifiers are needed to reproduce low-frequency sounds. While an electric guitarist would be able to play at a small club with a 50-watt amplifier, a bass player performing in the same venue would probably need an amplifier with 200 or more watts.

Marshall is a popular amplifier manufacturer for metal and hard rock. Pictured is the MG15DFX guitar amplifier.

Distortion is a feature available on many guitar amplifiers that is not typically found on keyboard or bass guitar amplifiers. Tube guitar amplifiers can produce distortion through pre-distortion equalization, preamp tube distortion, post-distortion EQ, power-tube distortion, tube rectifier compression, output transformer distortion, guitar speaker distortion, and guitar speaker and cabinet frequency response. Because there are so many factors beyond preamp distortion that create a guitarist's "signature sound", in recording and sound reinforcement applications, the sound of the guitar amp is almost always recorded with a microphone placed in front of the guitar speaker, rather than using the guitar amp's pre-amp out signal (even though the guitar sound is typically recorded with a mic in front of the amp's speaker, for recordings, the sound engineer or music producer may ask for the DI out signal from the pickups to be recorded onto a separate track at the same time, so that the engineer or producer can re-amp the signal through various different amps at a later time). In contrast, it is fairly common to use a DI box with electric bass.

Distortion sound or "texture" from guitar amplifiers is further shaped or processed through the frequency response and distortion factors in the microphones (their response, placement, and multi-microphone comb filtering effects), microphone preamps, mixer channel equalization, and compression. Additionally, the basic sound produced by the guitar amplifier can be changed and shaped by adding distortion and/or equalization effect pedals before the amp's input jack, in the effects loop just before the tube power amp, or after the power tubes.

Power-tube distortion is required for amp sounds in some genres. In a standard master-volume guitar amp, as the amp's final or master volume is increased beyond the full power of the amplifier, power tube distortion is produced. The "power soak" approach places the attenuation between the power tubes and the guitar speaker. In the re-amped or "dummy load" approach, the tube power amp drives a mostly resistive dummy load while an additional low power amp drives the guitar speaker. In the isolation box approach, the guitar amplifier is used with a guitar speaker in a separate cabinet. A soundproofed isolation cabinet, isolation box, isolation booth, or isolation room can be used.

Even in the 2010s, the vintage Fender Bandmaster remains a sought-after amp by guitarists. Note the four inputs, two for regular sound and two which are run through the onboard vibrato effect unit. The amp pictured is a 1968 model.

A variety of labels are used for level attenuation potentiometers (knobs) in a guitar amplifier and other guitar equipment. Electric guitars and basses have a volume control on the instrument that attenuates the signal from selected pickups. There may be two volume controls on an electric guitar or bass, wired in parallel to mix the signal levels from the neck and bridge pickups. Rolling back the guitar's volume control also changes the pickup's equalization or frequency response, which can provide pre-distortion equalization.

The simplest guitar amplifiers, such as some vintage amps and modern practice amps, have only a single volume control. Most have two volume controls: a first volume control called "preamplifier" or "gain" and a master volume control. The preamp or gain control is designed differently on different types of guitar amps. On an amp designed for an acoustic guitar, turning up the preamp knob will preamplify the signal, but even at its maximum setting, the preamp control is unlikely to produce much overdrive. However, with amps designed for electric guitarists playing electric blues, hard rock and heavy metal music, turning up the preamp or gain knob will usually produce overdrive or distortion. Some electric guitar amps have three controls in the volume section: preamplifier, distortion and master control. Turning up the preamp and distortion knobs in varying combinations can create a range of overdrive tones, from a gentle, warm growling overdrive suitable for a traditional blues show or a rockabilly band to the extreme distortion used in hardcore punk and death metal. On some electric guitar amps, the "gain" knob is equivalent to the distortion control on a distortion pedal, and similarly may have a side-effect of changing the proportion of bass and treble sent to the next stage.

The patch bay at the rear panel of this Line 6 Flextone guitar amp provides a number of additional inputs and outputs, including stereo XLR DI unit outputs.

A simple, inexpensive amplifier may have only two tone controls, a passive bass and treble control. In some better quality amps, one or more midrange controls are provided. On the most expensive amps, there may be shelving equalizers for bass and treble, a number of mid-range controls (e.g., low mid, mid and high mid), and a graphic equalizer or parametric equalizer. The amplifier's master volume control restricts the amount of signal permitted through to the driver stage and the power amplifier. When using a power attenuator with a tube amplifier, the master volume no longer acts as the master volume control. Instead, the power attenuator's attenuation control controls the power delivered to the speaker, and the amplifier's master volume control determines the amount of power-tube distortion. Power-supply based power reduction is controlled by a knob on the tube power amp, variously labeled "wattage", "power", "scale", "power scale", or "power dampening".

Woodstock Online Guitar Lessons Vs Private Guitar Lessons

The bass guitar[1] (also called electric bass,[2][3][4] or simply bass) is a stringed instrument played primarily with the fingers or thumb, by plucking, slapping, popping, strumming, tapping, thumping, or picking with a plectrum, often known as a pick.

The bass guitar is similar in appearance and construction to an electric guitar, but with a longer neck and scale length, and four to six strings or courses. The four-string bass, by far the most common, is usually tuned the same as the double bass,[5] which corresponds to pitches one octave lower than the four lowest pitched strings of a guitar (E, A, D, and G).[6] The bass guitar is a transposing instrument, as it is notated in bass clef an octave higher than it sounds (as is the double bass) to avoid excessive ledger lines. Like the electric guitar, the bass guitar has pickups and needs to be connected to an amplifier and speaker, which makes a sound loud enough to hear.

Since the 1960s, the bass guitar has largely replaced the double bass in popular music as the bass instrument in the rhythm section.[7] While types of basslines vary widely from one style of music to another, the bassist usually plays a similar role: anchoring the harmonic framework and establishing the beat. Many styles of music include the bass guitar, including rock, heavy metal, pop, punk rock, country, reggae, gospel, blues, symphonic rock, and jazz. It is often a solo instrument in jazz, jazz fusion, Latin, funk, progressive rock and other rock and metal styles.

Musical instrument inventor Paul Tutmarc outside his music store in Seattle, Washington

In the 1930s, musician and inventor Paul Tutmarc from Seattle, Washington, who was manufacturing lap steel guitars, developed the first electric string bass in its modern form, a fretted instrument designed to be played horizontally. The 1935 sales catalog for Tutmarc's electronic musical instrument company, Audiovox, featured his "Model 736 Bass Fiddle", a four-stringed, solid-bodied, fretted electric bass instrument with a 30 1⁄2-inch (775 mm) scale length.[8] The adoption of a "guitar" form made the instrument easier to hold and transport than any of the existing stringed bass instruments. The addition of frets enabled bassists to play in tune more easily than on acoustic or electric upright basses. Around 100 of these instruments were made during this period.[9]

Around 1947, Tutmarc's son, Bud, began marketing a similar bass under the Serenader brand name, prominently advertised in the nationally distributed L. D. Heater Music Company wholesale jobber catalogue of 1948. However, the Tutmarc family inventions did not achieve market success.

An early Fender Precision Bass

In the 1950s, Leo Fender, with the help of his employee George Fullerton, developed the first mass-produced electric bass guitar.[10] Fender was the founder of Fender Electric Instrument Manufacturing Company, which made electric popular brands of electric guitars, basses and amplifiers. Fender's Fender Precision Bass, which began production in October 1951, became a widely copied industry standard for the instrument. The Precision Bass (or "P-bass") evolved from a simple, un-contoured "slab" body design and a single coil pickup similar to that of a Telecaster, to a contoured body design with beveled edges for comfort and a split single coil pickup.

Design patent issued to Leo Fender for the second-generation Precision Bass

The "Fender Bass" was a revolutionary new instrument for gigging musicians. In comparison with the upright bass, which had been the main bass instrument in popular music, folk and country from the early 1900s to the 1940s, the Fender bass could be easily transported to shows. It was also less prone to feedback when amplified, than acoustic bass instruments.[11] In 1953 Monk Montgomery became the first bass player to tour with the Fender bass guitar, in Lionel Hampton's postwar big band.[12] Roy Johnson, and Shifty Henry with Louis Jordan & His Tympany Five, were other early Fender bass pioneers.[10]Bill Black, playing with Elvis Presley, switched from upright bass to the Fender Precision Bass around 1957.[13] The bass guitar was intended to appeal to guitarists as well as upright bass players, and many early pioneers of the instrument, such as Carol Kaye and Joe Osborn, were originally guitarists.[14]

Following Fender's lead, in 1953, Gibson released the first short scale violin-shaped electric bass with extendable end pin, allowing it to be played upright or horizontally. Gibson renamed the Electric Bass in 1958 to the EB-1.[15] Also in 1958 Gibson released the maple arched top EB-2 described in the Gibson catalogue as "A hollow-body electric bass that features a Bass/Baritone pushbutton for two different tonal characteristics".[16] In 1959 these were followed by the more conventional-looking EB-0 Bass. The EB-0 was very similar to a Gibson SG in appearance (although the earliest examples have a slab-sided body shape closer to that of the double-cutaway Les Paul Special).

Gibson EB-3

Whereas Fender basses had pickups mounted in positions in between the base of the neck and the top of the bridge, many of Gibson's early basses featured one humbucking pickup mounted directly against the neck pocket. The EB-3, introduced in 1961, also had a "mini-humbucker" at the bridge position. Gibson basses also tended to be smaller, sleeker instruments; Gibson did not produce a 34-inch (864 mm) scale bass until 1963 with the release of the Thunderbird, which was also the first Gibson bass to use dual-humbucking pickups in a more traditional position, about halfway between the neck and bridge. A number of other companies also began manufacturing bass guitars during the 1950s: Kay in 1952, Hofner and Danelectro in 1956, Rickenbacker in 1957 and Burns/Supersound in 1958.[13]

1956 saw the appearance at the German trade fair "Musikmesse Frankfurt" of the distinctive Höfner 500/1 violin bass made using violin construction techniques by Walter Höfner, a second generation violin luthier.[17] The instrument is often known as the "Beatle Bass", due to its endorsement and use by Beatles bassist Paul McCartney. In 1957 Rickenbacker introduced the model 4000 bass,[18] the first bass to feature a neck-through-body design in which the neck is part of the body wood. The Fender and Gibson versions used bolt-on and glued-on necks.

With the explosion of the popularity of rock music in the 1960s, many more manufacturers began making electric basses, including the Japanese manufacturers Yamaha, Teisco and Guyatone. First introduced in 1960, the Fender Jazz Bass was known as the Deluxe Bass and was meant to accompany the Jazzmaster guitar. The Jazz Bass (often referred to as a "J-bass") featured two single-coil pickups, one close to the bridge and one in the Precision bass' split coil pickup position. The earliest production basses had a 'stacked' volume and tone control for each pickup. This was soon changed to the familiar configuration of a volume control for each pickup, and a single, passive tone control. The Jazz Bass' neck was narrower at the nut than the Precision bass — 1 1⁄2 inches (38 mm) versus 1 3⁄4 inches (44 mm) — allowing for easier access to the lower strings and an overall spacing and feel closer to that of an electric guitar, allowing trained guitarists to transition to the bass guitar more easily.

1970s Fender Jazz Bass with maple fretboard

Another visual difference that set the Jazz Bass apart from the Precision is its "offset-waist" body. Pickup shapes on electric basses are often referred to as "P" or "J" pickups in reference to the visual and electrical differences between the Precision Bass and Jazz Bass pickups.

Fender also began production of the Mustang Bass; a 30-inch (762 mm) scale length instrument used by bassists such as Tina Weymouth of Talking Heads and Bill Wyman of The Rolling Stones ("P" and "J" basses have a scale length of 34 inches (864 mm), a design echoed on most current production electric basses of all makes). In the 1950s and 1960s, the instrument was often called the "Fender bass", due to Fender's early dominance in the market. The Fender VI, a baritone guitar, was tuned one octave lower than standard guitar tuning. It was released in 1961, and was favored by Jack Bruce of Cream.[19]

Gibson introduced the short-scale 30 1⁄2-inch (775 mm) EB-3 in 1961, also used by Jack Bruce.[20]

A Rickenbacker 4001 bass.

In 1971, Alembic established the template for what became known as "boutique" or "high-end" electric bass guitars. These expensive, custom-tailored instruments, as used by Phil Lesh, Jack Casady, and Stanley Clarke, featured unique designs, premium hand-finished wood bodies, and innovative construction techniques such as multi-laminate neck-through-body construction and graphite necks. Alembic also pioneered the use of onboard electronics for pre-amplification and equalization. Active electronics increase the output of the instrument, and allow more options for controlling tonal flexibility. Giving the player the ability to amplify as well as attenuate (turn down) certain frequency ranges while improving the overall frequency response (more low-register and high-register sounds). 1973 saw the UK company Wal begin production of a their own range of active basses, and In 1974 Music Man Instruments, founded by Tom Walker, Forrest White and Leo Fender, introduced the StingRay, the first widely produced bass with active (powered) electronics.

Specific bass brands/models became identified with particular styles of music, such as the Rickenbacker 4001 series, which became identified with progressive rock bassists like Chris Squire of Yes, and Geddy Lee of Rush, while the StingRay was used by funk/disco players such Louis Johnson of the funk band The Brothers Johnson and Bernard Edwards of Chic. The 4001 stereo bass was introduced in the late 1960s; it can be heard on from the Beatles "I Am The Walrus".[citation needed]

In the mid-1970s, Alembic and other boutique bass manufacturers, such as Tobias, produced four-string and five-string basses with a low "B" string. In 1975, bassist Anthony Jackson commissioned luthier Carl Thompson to build a six-string bass tuned (low to high) B0, E1, A1, D2, G2, C3. In comparison with a standard four-string bass, Jackson's six-string adds a low B string and a high C string. These 5 and 6-string "extended-range basses" would become popular with session bassists as they reduced the need for re-tuning to alternate detuned configurations like "drop D", and also allowed the bassist to play more notes from the same position on the fretboard with fewer shifts up and down the fingerboard, a crucial benefit for a session player sightreading basslines at a recording session.

An early 1980s-era Steinberger headless bass. The tuning machines are at the heel of the instrument, where the bridge is usually located.

In the 1980s, bass designers continued to explore new approaches. Ned Steinberger introduced a headless bass in 1979 and continued his innovations in the 1980s, using graphite and other new materials and (in 1984) introducing the TransTrem tremolo bar. In 1982, Hans-Peter Wilfer founded Warwick, to make a European bass, as the market at the time was dominated by Asian and American basses. Their first bass was the Streamer Bass, which is similar to the Spector NS. In 1987, the Guild Guitar Corporation launched the fretless Ashbory bass, which used silicone rubber strings and a piezoelectric pickup to achieve a "upright bass" sound with a short 18-inch (457 mm) scale length. In the late 1980s, MTV's "Unplugged" show, which featured bands performing with acoustic instruments, helped to popularize hollow-bodied acoustic bass guitars amplified with piezoelectric pickups built into the bridge of the instrument.

During the 1990s, as five-string basses became more widely available and more affordable, an increasing number of bassists in genres ranging from metal to gospel began using five-string instruments for added lower range—a low "B" string. As well, onboard battery-powered electronics such as preamplifiers and equalizer circuits, which were previously only available on expensive "boutique" instruments, became increasingly available on mid-priced basses. From 2000 to the 2010s, some bass manufacturers included digital modelling circuits inside the instrument on more costly instruments to recreate tones and sounds from many models of basses (e.g., Line 6's Variax bass). A modelling bass can digitally emulate the tone and sound of many famous basses, ranging from a vintage Fender Precision to a Rickenbacker. However, as with the electric guitar, traditional "passive" bass designs, which include only pickups, tone and volume knobs (without a preamp or other electronics) remained popular. Reissued versions of vintage instruments such as the Fender Precision Bass and Fender Jazz Bass remained popular amongst new instrument buyers up to the 2010s. In 2011, a 60th Anniversary P-bass was introduced by Fender, along with the re-introduction of the short-scale Fender Jaguar Bass.

Bass bodies are typically made of wood, although other materials such as graphite (for example, some of the Steinberger designs) and other lightweight composite materials have also been used. While a wide variety of woods are suitable for use in the body, neck, and fretboard of the bass guitar, the most common types of wood used are similar to those used for electric guitars; alder, ash or mahogany for the body, maple for the neck, and rosewood or ebony for the fretboard. While these traditional standards are most common, for tonal or aesthetic reasons luthiers more commonly experiment with different tonewoods on basses than with electric guitars (though this is changing), and rarer woods like walnut and figured maple, as well as exotic woods like bubinga, wenge, koa, and purpleheart, are often used as accent woods in the neck or on the face of mid- to high-priced production basses and on custom-made and boutique instruments.

Other design options include finishes, such as lacquer, wax and oil; flat and carved designs; luthier-produced custom-designed instruments; headless basses, which have tuning machines in the bridge of the instrument (e.g., Steinberger and Hohner designs) and several artificial materials such as luthite. The use of artificial materials (e.g., BassLab) allows for unique production techniques such as die-casting, to produce complex body shapes. While most basses have solid bodies, they can also include hollow chambers to increase the resonance or reduce the weight of the instrument. Some basses are built with entirely hollow bodies, which change the tone and resonance of the instrument. Acoustic bass guitars have a hollow wooden body constructed similarly to an acoustic guitar, and are typically equipped with piezoelectric or magnetic pickups and amplified.

Instruments handmade by highly skilled luthiers are becoming increasingly available in the 2010s. Exotic materials used in high-end instruments include woods such as bubinga, wenge, ovangkol, ebony and goncalo alves. Graphite composite is used to make lightweight necks[21][22] Exotic woods are used on more expensive instruments: for example, Alembic uses cocobolo as a body or top layer material because of its attractive grain. Warwick bass guitars are also well known for exotic hardwoods: most of the necks are made of ovangkol, and the fingerboards use wenge or ebony. Solid bubinga bodies are also used for their tonal and aesthetic qualities.

A common feature of more expensive basses is "neck-through" construction. Instead of milling the body from a single piece of wood (or "bookmatched" halves) and then attaching the neck into a pocket (so-called "bolt-on" design), neck-through basses are constructed first by assembling the neck, which may comprise one, three, five or more layers of wood in vertical stripes, which are longer than the length of the fretboard. To this elongated neck, the body is attached as two wings, which may also be made up of several layers. The entire bass is then milled and shaped. Neck-through construction advertisements claim this approach provides better sustain and a mellower tone than bolt-on neck construction. While neck-through construction is most common in handmade "boutique" basses, some models of mass-produced basses such as Ibanez's BTB series also have neck-through construction. Bolt-on neck construction does not necessarily imply a cheaply made instrument; virtually all traditional Fender designs still use bolt-on necks, including its high-end instruments costing thousands of dollars, and many boutique luthiers such as Sadowsky build bolt-on basses as well as neck-through instruments.

The number of frets installed on a bass guitar neck may vary. The original Fender basses had 20 frets, and most bass guitars have between 20 and 24 frets or fret positions. Instruments with between 24 and 36 frets (2 and 3 octaves) also exist. Instruments with more frets are used by bassists who play bass solos, as more frets gives them additional upper range notes. When a bass has a large number of frets, such as a 36 fret instrument, the bass may have a deeper "cutaway" to enable the performer to reach the higher pitches. Like electric guitars, fretted basses typically have markers on the fingerboard and on the side of the neck to assist the player in determining where notes and important harmonic points are. The markers indicate the 3rd, 5th, 7th, 9th fret and 12th fret (the 12th fret being the octave of the open string) and on the octave-up equivalents of the 3rd fret and as many additional positions as an instrument has frets for. Typically, one marker is used for the 3rd, 5th, 7th and 9th fret positions and two markers are used for the 12th fret.

The long scale necks on Leo Fender's basses—with a scale length (distance between nut and bridge) of 34 inches (864 mm) — set the standard for electric basses, although 30-inch (762 mm) "short scale" instruments, such as the Höfner 500/1 "violin bass" played by Paul McCartney, and the Fender Mustang Bass are also common. Short scale instruments use the same E-A-D-G tuning as a regular long scale instrument. Short scale instruments are good choices for bassists with smaller hands, such as children or young teens who are just starting the instrument. While 35-inch (889 mm), 35 1⁄2-inch (902 mm), and 36-inch (914 mm) scale lengths were once only available in "boutique" instruments, in the 2000s (decade), many manufacturers began offering these "extra long" scale lengths. This extra long scale provides a higher string tension, which may yield a more defined, deep tone on the low "B" string of five- and six-stringed instruments (or detuned four-string basses).

Another design consideration for the bass is whether to use frets on the fingerboard. On a fretted bass, the metal frets divide the fingerboard into semitone divisions (as on an electric guitar or acoustic guitar). Fretless basses have a distinct sound, because the absence of frets means that the string must be pressed down directly onto the wood of the fingerboard with the fingers, as with the double bass. The string buzzes against the wood and is somewhat muted because the sounding portion of the string is in direct contact with the flesh of the player's finger. The fretless bass allows players to use the expressive approaches such as glissando (sliding up or down in pitch, with all of the pitches in between sounding), and true vibrato (in which the player alternates adds expression to a note by rocking the finger which is stopping the note and raising or lowering the pitch slightly). Players may also play music utilising microtones, or temperaments other than equal temperament, such as just intonation.

While fretless basses are often associated with jazz and jazz fusion, bassists from other genres have used fretless basses, such as Freebo (country), Rick Danko (rock/blues), Rod Clements (folk), Steve DiGiorgio (metal) and Colin Edwin (modern/progressive rock). Some bassists alternate between fretted and fretless basses in performances, according to the type of material or tunes they are performing, e.g., Pino Palladino or Tony Levin.

The first fretless bass guitar was made by Bill Wyman in 1961 when he converted an inexpensive Japanese fretted bass by simply removing the frets and filling in the slots cut into the neck with wood putty.[23][24] The first production fretless bass was the Ampeg AUB-1 introduced in 1966, and Fender introduced a fretless Precision Bass in 1970. Around 1970, Rick Danko from The Band began to use an Ampeg fretless, which he modified with Fender pickups—as heard on the 1971 Cahoots studio album and the Rock of Ages album recorded live in 1971.[25][26] Danko said, "It's a challenge to play fretless because you have to really use your ear."[27] In the early 1970s, fusion-jazz bassist Jaco Pastorius had the fingerboard of his de-fretted Fender Jazz Bass coated in epoxy resin, allowing him to use roundwound strings for a brighter sound.[28] Some fretless basses have "fret line" markers inlaid in the fingerboard as a guide, while others only use guide marks on the side of the neck.

Tapewound (double bass type) and flatwound strings are sometimes used with the fretless bass so the metal string windings do not wear down the fingerboard. Tapewound and flatwound strings have a distinctive tone and sound. Some fretless basses have epoxy-coated fingerboards, or fingerboards made of an epoxy composite like micarta, to increase the fingerboard's durability, enhance sustain, and give a brighter tone.

The tuning machines (with spiral metal worm gears) are mounted on the back of the headstock on the bass guitar neck.

The standard design for the electric bass guitar has four strings, tuned E, A, D and G,[29] in fourths such that the open highest string, G, is an eleventh (an octave and a fourth) below middle C, making the tuning of all four strings the same as that of the double bass (E1–A1–D2–G2). This tuning is also the same as the standard tuning on the lower four strings on a six-string guitar, only an octave lower.

There are a range of different string types include all-metal strings (which are available in many varieties, including roundwound, flatwound, halfwound, ground wound, and pressure wound); as well as metal strings with different coverings, such as tapewound and wound with plastic coatings. The variety of materials used in the strings gives bass players a range of tonal options. In the 1950s and early 1960s, bassists mostly used flatwound strings with a smooth surface, which had a smooth, damped sound reminiscent of a double bass. In the late 1960s and 1970s, roundwound bass strings producing a brighter tone similar to steel guitar strings became popular, though flatwounds also remain in use by players seeking a vintage tone. Roundwounds have a brighter timbre with longer sustain than flatwounds.

A variety of tuning options and number of string courses have been used to extend the range of the instrument, or facilitate different modes of playing. The most common are four, five, or six strings:

The dots below the frets are often inlaid into the wood of bass necks, as a visual aid to help the player find different positions. A bass guitar headstock with detuner set to D position. A seven-string fretless bass

Some bassists use other types of tuning to extend the range or get other benefits, such as providing multiple octaves of notes at any given position, or a larger tonal range. Instrument types or tunings used for this purpose include basses with fewer than four strings (one-string bass guitars,[32] two-string bass guitars, three-string bass guitars [tuned to E–A–D])[33] and alternative tunings e.g., tenor bass.[34]

Extended range basses (ERBs) are basses with six to twelve strings—with the additional strings used for range rather than unison or octave pairs. A seven-string bass (B0–E1–A1–D2–G2–C3–F3) was built by luthier Michael Tobias in 1987. This instrument, commissioned by bassist Garry Goodman, was an early example of a bass with more than six single course strings. In 1999 South American ERB player Igor Saavedra designed one of the first eight-string ERBs known, and asked Luthier Alfonso Iturra to build it for him. [35] Conklin builds custom ERB basses.[36] The Guitarbass is a ten-string instrument with four bass strings (tuned E–A–D–G) and six guitar strings (tuned E–A–D–G–B–E).[37] Luthier Michael Adler built the first eleven-string bass in 2004 and completed the first single-course 12-string bass in 2005. Adler's 11- and 12-string instruments have the same range as a grand piano.[38] Subcontrabasses, such as C–F–B–E (the lowest string, C0 being at 17.32 Hz at around the limit of human hearing)[39] have been created. Ibanez had released SR7VIISC in 2009, featuring a 30-inch (762 mm) scale and narrower width, and tuned as B–E–A–D–G–C–E; the company dubbed it a cross between bass and guitar.[40][better source needed]

In 2011 Warwick released a new Thumb NT 7 bass for Jeroen Paul Thesseling, featuring a 34-inch (864 mm) scale with subcontra tuning F–B–E–A–D–G–C. Yves Carbonne developed ten- and twelve-string fretless subbass guitars.[41][42][43]

Piccolo basses are cosmetically similar to a four-stringed electric bass guitar, but usually tuned one whole octave higher than a normal bass. The first electric piccolo bass was constructed by luthier Carl Thompson for Stanley Clarke.[citation needed] To allow for the raised tuning, the strings are thinner, and the length of the neck (the scale) may be shorter. Several companies manufacture piccolo sets that can be put on any regular bass, thereby converting any bass into a piccolo bass. Because of the thinner strings, a new nut may be required to hold the strings. Some people prefer a slightly shorter scale, such as 30 or 28 inches (762 or 711 mm), as the higher tension required for longer scale lengths coupled with the thinner gauge of higher-pitched strings can make a long-scale piccolo bass difficult to play. The tuning varies with the personal tastes of the artist, as does the number of strings. Joey DeMaio from the heavy metal band Manowar plays with four strings on his piccolo bass. Jazz bassist John Patitucci used a six-string piccolo bass, unaccompanied, on his song "Sachi's Eyes" on his album One More Angel. Michael Manring has used a five-string piccolo bass in several altered tunings. Michael uses D'Addario EXL 280 piccolo bass strings on his four-string hyperbass, made by Zon Guitars.[citation needed]

For more information on pickups, see Pick up (music technology).

Most electric bass guitars use magnetic pickups. The vibrations of the instrument's ferrous metal strings within the magnetic field of the permanent magnets in magnetic pickups produce small variations in the magnetic flux threading the coils of the pickups. This in turn produces small electrical voltages in the coils. These low-level signals are then amplified and played through a speaker. Most basses have a volume potentiometer, which can be turned up or down, and a tone potentiometer, which rolls off the high frequencies when it is turned to the player's right. Some basses may also have a pickup selector control or switch. Since the 1980s, basses are often available with battery-powered "active" electronics that boost the signal with a preamplifier, provide equalization controls to boost or cut bass and treble frequencies, or both.

P-style, split-coil pickups Dual "J"-style pickups A Yamaha BB404F, which has two passive single coil pickups

Many basses have just one pickup, typically a "P" or "MM" pickup, though single soapbars are not unheard of. Multiple pickups are also quite common, two of the most common configurations being two "J" pickups (as on the stock Fender Jazz), or a "P" near the neck and a "J" near the bridge (e.g., Fender Precision Bass Special, Fender Precision Bass Plus). A two-"soapbar" configuration is also very common, especially on basses by makes such as Ibanez and Yamaha. A combination of a J or other single-coil pickup at the neck and a Music Man-style humbucker in the bridge has become popular among boutique builders, giving a very bright, focused tone that is good for jazz, funk and thumbstyle.

Some basses use more unusual pickup configurations, such as a soapbar and a "P" pickup (found on some Fenders), Stu Hamm's "Urge" basses, which have a "P" pickup sandwiched between two "J" pickups, and some of Bootsy Collins' custom basses, which had as many as 5 J pickups. Another unusual pickup configuration is found on some of the custom basses that Billy Sheehan uses, in which there is one humbucker at the neck and a split-coil pickup at the middle position.

The placement of the pickup greatly affects the sound. A pickup near the neck joint emphasizes the fundamental and low-order harmonics and thus produces a deeper, bassier sound, while a pickup near the bridge emphasizes higher-order harmonics and makes a "tighter" or "sharper" sound. Usually basses with multiple pickups allow blending of the output from the pickups, with electrical and acoustical interactions between the two pickups (such as partial phase cancellations) allowing a range of tonal effects.

The use of non-magnetic pickups allows bassists to use non-ferrous strings such as nylon, brass, polyurethane and silicone rubber. These materials produce different tones and, in the case of the polyurethane or silicone rubber strings, allow much shorter scale lengths.

Main article: Bass instrument amplification This amplification setup is a "bass stack" approach, in which an amplifier (in this case a Hartke 5000) is plugged into separate speaker cabinets.

Like the electric guitar, the electric bass guitar is almost always connected to an amplifier and a speaker with a patch cord for live performances. Electric bassists use either a "combo" amplifier, which combines an amplifier and a speaker in a single cabinet, or an amplifier and one or more speaker cabinets (typically stacked, with the amplifier sitting on the speaker cabinets, leading to the term "half-stack" for one cabinet setups and "full stack" for two).

In most genres, a "clean" bass tone (without any amplifier-induced "overdrive" or "distortion") is desirable, and so while guitarists often prefer the more desirable distorted tones of tube-transistor amplifiers, bassists commonly use solid-state amplifier circuitry to achieve the necessary high output wattages with less weight than tubes (though smaller tubes can often still be found in the low-power "preamplifier" sections of the system, where they provide a warmer, smoother character to the bass tone for relatively little additional weight). A few all-tube bass amplifiers are still available, notably from the Ampeg brand.

In some cases, when the bass is used with large-scale PA amplification, it is plugged into a "DI" or direct box, which routes the signal to the bass amp while also sending the signal directly into a mixing console, and thence to the main and monitor speakers. When a recording of bass is being made, engineers may use a microphone set up in front of the amplifier's speaker cabinet for the amplified signal, a direct box signal that feeds the recording console, or a mix of both.

Various electronic bass effects such as preamplifiers, "stomp box"-style pedals and signal processors and the configuration of the amplifier and speaker can be used to alter the basic sound of the instrument. In the 1990s and early 2000s (decade), signal processors such as equalizers, overdrive devices (sometimes referred to as "fuzz bass"[45]), and compressors or limiters became increasingly popular. Modulation effects like chorus, flanging, phase shifting, and time effects such as delay and looping are less commonly used with bass than with electric guitar, but they are used in some styles of music.

Most bass players stand while playing, using a strap over the shoulder to hold the instrument, although sitting is also accepted, particularly in large ensemble settings, such as jazz big bands or in acoustic genres such as folk music. Some bassists, such as Jah Wobble, alternate between standing or seated playing. It is a matter of the player's preference as to which position gives the greatest ease of playing and what a bandleader expects. When sitting, right-handed players can balance the instrument on the right thigh or like classical guitar players, the left. When sitting, no strap is required. Balancing the bass on the left thigh usually positions it in such a way that it mimics the standing position, allowing for less difference between the standing and sitting positions. Balancing the bass on the right thigh provides better access to the neck and fretboard in its entirety, especially the lower-pitched frets.

James Jamerson was an influential bassist from the Motown era.

In contrast to the upright bass (or double bass), the electric bass guitar is played horizontally across the body, like an electric guitar. When the strings are plucked with the fingers (pizzicato), the index and middle fingers (and sometimes the thumb, ring, and little fingers as well) are used. James Jamerson, an influential bassist from the Motown era, played intricate bass lines using only his index finger, which he called "The Hook." There are also variations in how a bassist chooses to rest the right-hand thumb (or left thumb in the case of left-handed players). A player may rest his or her thumb on the top edge of one of the pickups or on the side of the fretboard, which is especially common among bassists who have an upright bass influence. Some bassists anchor their thumbs on the lowest string and move it off to play on the low string. Alternatively, the thumb can be rested loosely on the strings to mute the unused strings.

The string can be plucked at any point between the bridge and the point where the fretting hand is holding down the string; different timbres are produced depending on where along the string it is plucked. When plucked closer to the bridge, the string's harmonics are more pronounced, giving a brighter tone. Closer to the middle of the string, these harmonics are less pronounced, giving a more mellow tone.

Bassists trying to emulate the sound of a double bass sometimes pluck the strings with their thumb and use palm-muting to create a short, "thumpy" tone. The late Monk Montgomery (who played in Lionel Hampton's band) and Bruce Palmer (who performed with Buffalo Springfield) use thumb downstrokes. The use of the thumb was acknowledged by early Fender models, which came with a "thumbrest" or "Tug Bar" attached to the pickguard below the strings. Contrary to its name, this was not used to rest the thumb, but to provide leverage while using the thumb to pluck the strings. The thumbrest was moved above the strings in 1970s models (as a true thumbrest) and eliminated in the 1980s.

Main article: Slapping (music) This picture shows the position and form of the slapping hand, for the slap bass style. The side of the thumb is used to "slap" one of the lower strings, while the fingers are used to "pop" notes from one of the two higher strings.

The slap and pop method, or "thumbstyle", most associated with funk, uses tones and percussive sounds achieved by striking, thumping, or "slapping" a string with the thumb and snapping (or "popping") a string or strings with the index or middle fingers. Bassists often interpolate left hand-muted "dead notes" between the slaps and pops to achieve a rapid percussive effect, and after a note is slapped or popped, the fretting hand may cause other notes to sound by using "hammer ons", "pull offs", or a left-hand glissando (slide). Larry Graham of Sly and the Family Stone and Graham Central Station was an early innovator of the slap style, and Louis Johnson of The Brothers Johnson is also credited as an early slap bass player.

Slap and pop style is also used by many bassists in other genres, such as rock (e.g., J J Burnel and Les Claypool), metal (e.g., Eric Langlois, Martin Mendez, Fieldy and Ryan Martinie), and fusion (e.g., Marcus Miller, Victor Wooten and Alain Caron). Slap style playing was popularized throughout the 1980s and early 1990s by pop bass players such as Mark King (from Level 42) and rock bassists such as with Pino Palladino (currently a member of the John Mayer Trio and bassist for The Who),[46]Flea (from the Red Hot Chili Peppers) and Alex Katunich (from Incubus). Spank bass developed from the slap and pop style and treats the electric bass as a percussion instrument, striking the strings above the pickups with an open palmed hand. Wooten popularized the "double thump," in which the string is slapped twice, on the upstroke and a downstroke (for more information, see Classical Thump). A rarely used playing technique related to slapping is the use of wooden dowel "funk fingers", an approach popularized by Tony Levin.

The pick (or plectrum) is used to obtain a more articulate attack, for speed, or just personal preference. Although the use of a pick is primarily associated with rock and punk rock, picks are also used in other styles. Jazz bassist Steve Swallow often plays with a pick,[citation needed] while Pink Floyd bassist Roger Waters uses one for a heavier tone. Mike Gordon of Phish uses a pick while also incorporating slapping techniques into his playing. Picks can be used with alternating downstrokes and upstrokes, or with all downstrokes for a more consistent attack. The pick is usually held with the index and thumb, with the up-and-down plucking motion supplied by the wrist.

There are many varieties of picks available, but due to the thicker, heavier strings of the electric bass, bassists tend to use heavier picks than those used for electric guitar, typically ranging from 1.14 mm–3.00 mm (3.00 is unusual). Different materials are used for picks, including plastic, nylon, rubber, and felt, all of which produce different tones. Felt and rubber picks are used to emulate a fingerstyle tone.

Palm-muting is a widely used bass technique. The outer edge of the palm of the picking hand is rested on the bridge while picking, and "mutes" the strings, shortening the sustain time. The harder the palm presses, or the more string area that is contacted by the palm, the shorter the string's sustain. The sustain of the picked note can be varied for each note or phrase. The shorter sustain of a muted note on an electric bass can be used to imitate the shorter sustain and character of an upright bass. Palm-muting is commonly done while using a pick, but can also be done without a pick, as when doing down-strokes with the thumb.

One prominent example of the pick/palm-muting combination is Paul McCartney, who has consistently used this technique for decades. Sting also uses palm-muting; but often does so without a pick, using the thumb and first finger to pluck.

This photo illustrates how Paul McCartney mutes the strings with his picking hand.

The fretting hand, the left hand for right-handed bass players and the right hand for left-handed bass players, is used to press down the strings to play different notes and shape the tone or timbre of a plucked or picked note. The fundamental technique used in the fretting hand is known as "a finger per fret", where each finger in the fretting hand plays one fret in a given position. Also, the double bass technique can be used for fretting. This technique involves the use of four fingers in the space of three frets, especially in the lower positions. When considering the spacing between notes, this is a comfortable distance for the average person's hand size. The main advantage of the "four fingers in three frets" technique is less tendon strain, leading to a diminished likelihood of Repetitive Strain Injury (RSI). The "four-in-three" technique is demonstrated in the image below (A bassist performing tapping).

The fretting hand can be used to change a sounded note, either by fully muting it after it is plucked or picked to shorten its duration or by partially muting it near the bridge to reduce the volume of the note, or make the note die away faster. The fretting hand is often used to mute strings that are not being played and stop the sympathetic vibrations, particularly when the player wants a "dry" or "focused" sound. On the other hand, the sympathetic resonance of harmonically related strings may be desired for some songs, such as ballads. In these cases, a bassist can fret harmonically related notes. For example, while fretting a sustained "F" (on the third fret of the "D" string), underneath an F major chord being played by a piano player, a bassist might hold down the "C" and low "F" below this note so their harmonics sound sympathetically.

The fretting hand can add vibrato to a plucked or picked note, either a gentle, narrow vibrato or a more exaggerated, wide vibrato with bigger pitch variations. For fretted basses, vibrato is always an alternation between the pitch of the note and a slightly higher pitch. For fretless basses, the player can use this style of vibrato, or they can alternate between the note and a slightly lower pitch, as is done with the double bass and on other unfretted stringed instruments. While vibrato is mostly done on "stopped" notes—that is, notes that are pressed down on the fingerboard—open strings can also be vibratoed by pressing down on the string behind the nut. As well, the fretting hand can be used to "bend" a plucked or picked note up in pitch, by pushing or pulling the string so that the note sounds at a higher pitch. To create the opposite effect, a "bend down", the string is pushed to a higher pitch before being plucked or picked and then allowed to fall to the lower, regular pitch after it is sounded. Though rare, some bassists may use a tremolo bar-equipped bass to produce the same effect.

In addition to pressing down one note at a time, bassists can also press down several notes at one time with their fretting hand to perform a double stop (two notes at once) or a chord. While double stops and chords are used less often by bassists than by electric guitarists playing rhythm guitar, a variety of double stops and chords can be performed on the electric bass. Some double stops used by bassists include octaves. Chords can be especially with effective on instruments with higher ranges such as six-string basses. Another variation to fully pressing down a string is to gently graze the string with the finger at the harmonic node points on the string, which creates chime-like upper partials (also called "overtones"). Glissando is an effect in which the fretting hand slides up or down the neck, which can be used to create a slide in pitch up or down. A subtle glissando can be performed by moving the fretting hand without plucking or picking the string; for a more pronounced effect, the string is plucked or picked first, or, in a metal or hardcore punk context, a pick may be scraped along the sides of the lower strings.

A bassist performing tapping, in which notes are sounded by striking the strings against the fretboard

The fretting hand can also be used to sound notes, either by plucking an open string with the fretting hand, or, in the case of a string that has already been plucked or picked, by "hammering on" a higher pitch or "pulling off" a finger to pluck a lower fretted or open stringed note. Jazz bassists use a subtle form of fretting hand pizzicato by plucking a very brief open string grace note with the fretting hand right before playing the string with the plucking hand. When a string is rapidly hammered on, the note can be prolonged into a trill.

In the two-handed tapping styles, bassists use both hands to play notes on the fretboard by rapidly pressing and holding the string to the fret. Instead of plucking or picking the string to create a sound, in this technique, the action of striking the string against the fret or the fretboard creates the sound. Since two hands can be used to play on the fretboard, this makes it possible to play interweaving contrapuntal lines, to simultaneously play a bass line and a simple chord, or play chords and arpeggios. Bassist John Entwistle of The Who tapped percussively on the strings, causing them to strike the fretboard with a twangy sound to create drum-style fills.[citation needed] Players noted for this technique include Cliff Burton, Billy Sheehan, Stuart Hamm, John Myung, Victor Wooten, Les Claypool, Mark King, and Michael Manring. The Chapman Stick and Warr Guitars are string instruments specifically designed to be played using two-handed tapping.

Strumming, usually with finger nails, is a common technique on acoustic guitar, but it is not a commonly used technique for bass. However, a notable example is Stanley Clarke's bass playing on the introduction to "School Days", on the album of the same name.[47]

Popular music bands and rock groups use the bass guitar as a member of the rhythm section, which provides the chord sequence or "progression" and sets out the "beat" for the song. The rhythm section typically consists of a rhythm guitarist or electric keyboard player, or both, a bass guitarist and a drummer; larger groups may add additional guitarists, keyboardists, or percussionists.

Bassists often play a bass line composed by an arranger, songwriter or composer of a song—or, in the case of a cover song, the bass line from the original. In other bands—e.g., jazz-rock bands that play from lead sheets and country bands using the Nashville number system—bassists are expected to improvise or prepare their own part to fit the song's chord progression and rhythmic style.

This sample illustrates a simple pop bass line over a D major progression

Types of bass lines vary widely, depending on musical style. However, the bass guitarist generally fulfills a similar role: anchoring the harmonic framework (often by emphasizing the roots of the chord progression) and laying down the beat in collaboration with the drummer and other rhythm section instruments. The importance of the bass guitarist and the bass line varies in different styles of music. In some pop styles, such as 1980s-era pop and musical theater, the bass sometimes plays a relatively simple part as the music emphasizes vocals and melody instruments. In contrast, in reggae, funk, or hip-hop, entire songs may center on the bass groove, and the bass line is usually prominent in the mix.

In traditional music such as country music, folk rock, and related styles, the bass often plays the roots and fifth (typically the fifth below the root) of each chord in alternation. In these styles, bassists often use scalar "walkups" or "walkdowns" when there is a chord change. In Chicago blues, the electric bass often performs a walking bassline made up of scales and arpeggios. In blues rock bands, the bassist often plays blues scale-based riffs and chugging boogie-style lines. In metal, the bass guitar may perform complex riffs along with the rhythm guitarist or play a low, rumbling pedal point to anchor the group's sound.

A blues bass line played with a pick

The bass guitarist sometimes breaks out of the strict rhythm section role to perform bass breaks or bass solos. The types of bass lines used for bass breaks or bass solos vary by style. In a rock band, a bass break may consist of the bassist playing a riff or lick during a pause in the song. In some styles of metal, a bass break may consist of "shred guitar"-style tapping on the bass. In a funk or funk rock band, a bass solo may showcase the bassist's percussive slap and pop playing. In genres such as progressive rock, art rock, or progressive metal, the bass guitar player may play melody lines along with the lead guitar (or vocalist) and perform extended guitar solos.

Chords are not used that often by electric bass players. However, in some styles, bassists may sound "double stops", such as octaves with open strings and powerchords. In Latin music, double stops with fifths are used.[48]Robert Trujillo of Metallica is known for playing "massive chords" [49] and "chord-based harmonics" [50] on the bass. Lemmy of Motörhead often played power chords in his bass lines.

While bass guitar solos are not common in popular music, some artists, particularly in the heavy metal, funk, and progressive rock genres, do utilize them. In a rock context, bass guitar solos are structured and performed in a similar fashion as rock guitar solos, often with the musical accompaniment from the verse or chorus sections.

Bass solos are performed using a range of different techniques, such as plucking or fingerpicking. In the 1960s, The Who's bassist, John Entwistle, performed a bass break on the song "My Generation" using a plectrum. He originally intended to use his fingers, but could not put his plectrum down quickly enough.[citation needed] This is considered as one of the first bass solos in rock music, and also one of the most recognizable. Led Zeppelin's "Good Times Bad Times", the first song on their first album, contains two brief bass solos, occurring after the song's first and third choruses. Queen's bassist, John Deacon, occasionally played bass solos, such as on the song "Liar". Metallica's 1983 debut Kill Em All includes the song "(Anesthesia) Pulling Teeth," consisting entirely of a bass solo played by Cliff Burton. John McVie of Fleetwood Mac performed a bass solo on "The Chain" from the 1977 Rumours album.

Manowar's bassist Joey DeMaio uses special piccolo bass for his extremely fast bass solos like "Sting of the Bumblebee" and "William's Tale". Green Day bassist Mike Dirnt played a bass solo on the song "Welcome To Paradise" from the 1994 album Dookie and on the song "Makeout Party" from the 2012 album ¡Dos!. U2 includes a bass solo most notably on "Gloria", in which Adam Clayton utilizes several playing techniques. Matt Freeman of Rancid performs a very fast, guitar-like bass solo in the song "Maxwell Murder". Blink-182's "Voyeur" has a bass solo, which is featured on both their studio album Dude Ranch & their live album The Mark, Tom and Travis Show (The Enema Strikes Back!).

Heavy metal bass players such as Geezer Butler (Black Sabbath), Alex Webster (Cannibal Corpse), Cliff Burton (Metallica), and Les Claypool (Primus, Blind Illusion) have used chime-like harmonics and rapid plucking techniques in their bass solos. Geddy Lee of Rush has made frequent use of bass solos, such as on the instrumental "YYZ". In both published Van Halen concert videos, Michael Anthony performs unique maneuvers and actions during his solos. Funk bassists such as Larry Graham began using slapping and popping techniques for their solos, which coupled a percussive thumb-slapping technique of the lower strings with an aggressive finger-snap of the higher strings, often in rhythmic alternation. The slapping and popping technique incorporates a large number of muted (or 'ghost' tones) to normal notes to add to the rhythmic effect. Slapping and popping solos were prominent in 1980s pop and R&B, and they are still used by some modern funk and Latin bands.

When playing bass solos, rock and metal bassists sometimes use effects such as fuzz bass or a wah-wah pedal to produce a more pronounced sound. Notably, Cliff Burton of Metallica used both effects. Due to the lower range of the bass, bass guitar solos usually have a much lighter accompaniment than solos for other instruments. In some cases, the bass guitar solo is unaccompanied, or accompanied only by the drums.

The electric bass is a relative newcomer to the world of jazz. The big bands of the 1930s and 1940s Swing era and the small combos of the 1950s Bebop and Hard Bop movements all used the double bass. The electric bass was introduced in some bands in the 1950s and it became prominent during the late 1960s and early 1970s, when rock influences were blended with jazz to create jazz-rock fusion.

A walking bass line, as referred to below. It is called a "walking" bass line because of the way it rises and falls using scale notes and passing notes.

The introduction of the electric bass in jazz fusion, as in the rock world, helped bassists play in high-volume stadium concerts with powerful amplifiers, because it is easier to amplify the electric bass than the double bass (the latter is prone to feedback in high-volume settings). The electric bass has both an accompaniment and a soloing role in jazz. In accompaniment, the bassist may perform walking basslines for traditional tunes and jazz standards, playing smooth quarter note lines that imitate the double bass. For latin or salsa tunes and rock-infused jazz fusion tunes, the electric bass may play rapid, syncopated rhythmic figures in coordination with the drummer, or lay down a low, heavy groove.

In a jazz setting, the electric bass tends to have a much more expansive solo role than in most popular styles. In most rock settings, the bass guitarist may only have a few short bass breaks or brief solos during a concert. During a jazz concert, a jazz bassist may have a number of lengthy improvised solos, which are called "blowing" in jazz parlance. Whether a jazz bassist is comping (accompanying) or soloing, they usually aim to create a rhythmic drive and "timefeel" that creates a sense of "swing" and "groove". For information on notable jazz bassists, see the List of jazz bassists article.

Contemporary classical music uses both the standard instruments of Western Art music (piano, violin, double bass, etc.) and newer instruments or sound producing devices, ranging from electrically amplified instruments to tape players and radios.

The electric bass guitar has occasionally been used in contemporary classical music (art music) since the late 1960s. Contemporary composers often obtained unusual sounds or instrumental timbres through the use of non-traditional (or unconventional) instruments or playing techniques. As such, bass guitarists playing contemporary classical music may be instructed to pluck or strum the instrument in unusual ways.

However, contemporary classical composers may also write for the bass guitar in order to utilise its unique sound, and in particular its precise and piercing attack and timbre. For example, Steve Reich, explaining his decision to score 2x5 for two bass guitars, stated that "[with electric bass guitars] you can have interlocking bass lines, which on an acoustic bass, played pizzicato, would be mud".[51]

Russian and Soviet composer Alfred Schnittke, pictured here in 1989, used electric bass for his Symphony no. 1 (1972) and Symphony no. 3 (1981).

American composers using electric bass in the 1960s included experimental classical music composer Christian Wolff (born 1934) (Electric Spring 1, 1966; Electric Spring 2, 1966/70; Electric Spring 3, 1967; and Untitled, 1996); Francis Thorne, a student of Paul Hindemith at Yale University (born 1922), who wrote (Liebesrock 1968–69); and Krzysztof Penderecki (Cello Concerto no. 1, 1966/67, rev. 1971/72), The Devils of Loudun, 1969; Kosmogonia, 1970; and Partita, 1971), Louis Andriessen (Spektakel, 1970; De Staat, 1972–76; Hoketus, 1976; De Tijd, 1980–81 and De Materie, 1984–1988). European composers who began scoring for the bass guitar in the 1960s included Danish composer Pelle Gudmundsen-Holmgreen (born 1932) (Symfoni på Rygmarven, 1966; Rerepriser, 1967; and Piece by Piece, 1968); Irwin Bazelon (Churchill Downs, 1970).

In the 1970s, electric bass was used by the American conductor-composer Leonard Bernstein (1918–1990) for his MASS (1971). American jazz pianist Dave Brubeck used bass guitar for his 1971 piece Truth Has Fallen. Russian and Soviet composer Alfred Schnittke used the instrument for his Symphony no. 1, 1972. In 1977, David Amram (born 1930) scored for electric bass in En memoria de Chano Pozo. Amram is an American composer known for his eclectic use of jazz, ethnic and folk music.

In the 1980s (and in following decades), electric bass was used in works by Hans Werner Henze (El Rey de Harlem, 1980; and Il ritorno d'Ulisse in patria, 1981), Harold Shapero, On Green Mountain (Chaconne after Monteverdi), 1957, orchestrated 1981; Schnittke's Symphony no. 3 (1981); Steve Reich's Electric Counterpoint (1987) and 2x5 (2008), Wolfgang Rihm (Die Eroberung von Mexico, 1987–91), Arvo Pärt (Miserere, 1989/92), Steve Martland (Dance works, 1993; and Horses of Instruction, 1994), Sofia Gubaidulina (Aus dem Stundenbuch, 1991), Giya Kancheli (Wingless, 1993), John Adams (I Was Looking at the Ceiling and Then I Saw the Sky, 1995; and Scratchband, 1996/97), Michael Nyman (various works for the Michael Nyman Band), Mark-Anthony Turnage (Blood on the Floor, 1993–1996), numerous works by Art Jarvinen.[52]

The pedagogy and training for the electric bass varies widely by genre and country. Rock and pop bass has a history of pedagogy dating back to the 1950s and 1960s, when method books were developed to help students learn the instrument. One notable method book was Carol Kaye's How to Play the Electric Bass.

In the jazz scene, since the bass guitar takes on much of the same role as the double bass—laying down the rhythm, and outlining the harmonic foundation—electric bass players have long used both bass guitar methods and jazz double bass method books. The use of jazz double bass method books by electric bass players in jazz is facilitated in that jazz methods tend to emphasize improvisation techniques (e.g., how to improvise walking basslines) and rhythmic exercises rather than specific ways of holding or plucking the instrument.

Of all of the genres, jazz and the mainstream commercial genres (rock, R&B, etc.) have the most established and comprehensive systems of instruction and training for electric bass. In the jazz scene, teens can begin taking private lessons on the instrument and performing in amateur big bands at high schools or run by the community. Young adults who aspire to becoming professional jazz bassists or studio rock bassists can continue their studies in a variety of formal training settings, including colleges and some universities.

Several colleges offer electric bass training in the US. The Bass Institute of Technology (BIT) in Los Angeles was founded in 1978, as part of the Musician's Institute. Chuck Rainey (electric bassist for Aretha Franklin and Marvin Gaye) was BIT's first director. BIT was one of the earliest professional training program for electric bassists. The program teaches a range of modern styles, including funk, rock, jazz, Latin, and R&B.

The Berklee College of Music in Boston offers training for electric bass players. Electric bass students get private lessons and there is a choice of over 270 ensembles to play in. Specific electric bass courses include funk/fusion styles for bass; slap techniques for electric bass; fingerstyle R&B; five- and six-string electric bass playing (including performing chords); and how to read bass sheet music.[53] Berklee College alumni include Jeff Andrews, Victor Bailey, Jeff Berlin, Michael Manring, and Neil Stubenhaus.[53] The Bass Department has two rooms with bass amps for classes and ten private lesson studios equipped with audio recording gear. Berklee offers instruction for the four-, five-, and six-string electric bass, the fretless bass, and double bass. "Students learn concepts in Latin, funk, Motown, and hip-hop, ... jazz, rock, and fusion."[53]

In Canada, the Humber College Institute of Technology & Advanced Learning offers an Advanced Diploma (a three-year program) in jazz and commercial music. The program accepts performers who play bass, guitar, keyboard, drums, melody instruments (e.g., saxophone, flute, violin) and who sing. Students get private lessons and perform in 40 student ensembles.[54]

The Manhattan School of Music, at the intersection of West 122nd Street (Seminary Row) and Broadway

Although there are far fewer university programs that offer electric bass instruction in jazz and popular music, some universities offer bachelor's degrees (B.Mus.) and Master of Music (M.Mus.) degrees in jazz performance or "commercial music", where electric bass can be the main instrument. In the US, the Manhattan School of Music has a jazz program leading to B.Mus. and M.Mus degrees that accepts students who play bass (double bass and electric bass), guitar, piano, drums, and melody instruments (e.g., saxophone, trumpet, etc.).

In the Australian state of Victoria, the Victorian Curriculum and Assessment Authority has set out minimum standards for its electric bass students doing their end-of-year Solo performance recital. To graduate, students must perform pieces and songs from a set list that includes Baroque suite movements that were originally written for cello, 1960s Motown tunes, 1970s fusion jazz solos, and 1980s slap bass tunes. A typical program may include a Prelude by J.S. Bach; "Portrait of Tracy" by Jaco Pastorius; "Twisted" by Wardell Gray and Annie Ross; "What's Going On" by James Jamerson; and the funky Disco hit "Le Freak" by Chic.[55]

In addition to college and university diplomas and degrees, there are a variety of other training programs such as jazz or funk summer camps and festivals, which give students the opportunity to play a wide range of contemporary music, from 1970s-style jazz-rock fusion to 2000s-style R&B.

In other less mainstream genres, such as hardcore punk or metal, the pedagogical systems and training sequences are typically not formalized and institutionalized. As such, many players learn by ear, by copying bass lines from records and CDs, and by playing in a number of bands. Even in non-mainstream styles, though, students may be able to take lessons from experts in these or other styles, adapting learned techniques to their own style. As well, there are a range of books, playing methods, and, since the 1990s, instructional DVDs (e.g., how to play metal bass). In the 2010s, many instructional videos are available online on video-sharing websites such as YouTube.

The Pros and Cons of Private Acoustic Guitar Lessons

"Acoustic Guitars" redirects here. For the Danish group, see Acoustic Guitars (band). Example of a concert-shaped guitar by C.F. Martin

An acoustic guitar is a guitar that produces sound acoustically—by transmitting the vibration of the strings to the air—as opposed to relying on electronic amplification (see electric guitar). The sound waves from the strings of an acoustic guitar resonate through the guitar's body, creating sound. This typically involves the use of a sound board and a sound box to strengthen the vibrations of the strings.

The main source of sound in an acoustic guitar is the string, which is plucked or strummed with the finger or with a pick. The string vibrates at a necessary frequency and also creates many harmonics at various different frequencies. The frequencies produced can depend on string length, mass, and tension. The string causes the soundboard and sound box to vibrate, and as these have their own resonances at certain frequencies, they amplify some string harmonics more strongly than others, hence affecting the timbre produced by the instrument.

Gitterns, a small plucked guitar were the first small guitar-like instruments created during the Middle Ages with a round back like that of a lute.[1] Modern guitar shaped instruments were not seen until the Renaissance era where the body and size began to take a guitar-like shape.

The earliest string instruments that related to the guitar and its structure where broadly known as the vihuelas within Spanish musical culture. Vihuelas where string instruments that were commonly seen in the 16th century during the Renaissance. Later, Spanish writers distinguished these instruments into 2 categories of vihuelas. The vihuela de arco was an instrument that mimicked the violin, and the vihuela de penola was played with a plectrum or by hand. When it was played by hand it was known as the vihuela de mano. Vihuela de mano shared extreme similarities with the Renaissance guitar as it used hand movement at the sound hole or sound chamber of the instrument to create music.[2]

The real production of guitars kicked off in France where the popularity and production first began increasing with large quantities. Spain became the homeland of the guitar but there's very little information on the early makers there, unlike France, where many inventors and artists first began overproducing these instruments and their music. The production became so large that early famous creators such as Gaspard Duyffooprucgar's (a string instrument maker) instruments were being sold as copies by other guitar makers in Lyon. Benoist Lejeune, a guitar maker, offered and sold guitar copies of Duyffoprucgar's instruments and was later imprisoned for using his mark and work. During this time, the production was increasing tremendously but it was not until Robert and Claude Denis appeared overproducing the early Renaissance guitar in Paris, France. As father and son, Robert and Claude produced hundreds of guitars that increased the popularity of the instrument greatly. Because of them and the great many guitar inventors of this time, the word guiterne gradually shifted to guitarre during the sixteenth and seventeenth centuries.[3]

By 1790 only six-course vihuela guitars (6 unison-tuned pairs of strings) were being created and had become the main type and model of guitar used in Spain. Most of the older 5-course guitars were still in use but were also being modified to a six-coursed acoustical guitar. Fernando Ferandiere's Book Arte de tocar la guitarra espanola por musica (Madrid, 1799) describes the standard Spanish guitar from his time as an instrument with seventeen frets and six courses with the first two 'gut' strings tuned in unison called the terceras and the tuning named to 'G' of the two strings. The acoustic guitar at this time really began to take its shape with extreme similarities to the acoustic guitar today with the exception of the coursed strings which later were removed for single strings instead of pairs.[4]

By the 19th century, coursed strings where evolved into 6 single-stringed instruments much like that of the guitar today. It had evolved into the modern look except for size, retaining a smaller frame.

Example of a jumbo-shaped guitar by Gibson

The acoustic guitar's soundboard, or top, also has a strong effect on the loudness of the guitar. No amplification actually occurs in this process, because no external energy is added to increase the loudness of the sound (as would be the case with an electronic amplifier). All the energy is provided by the plucking of the string. But without a soundboard, the string would just "cut" through the air without actually moving it much. The soundboard increases the surface of the vibrating area in a process called mechanical impedance matching. The soundboard can move the air much more easily than the string alone, because it is large and flat. This increases the entire system's energy transfer efficiency, and a much louder sound is emitted.

In addition, the acoustic guitar has a hollow body, and an additional coupling and resonance effect increases the efficiency of energy transmission in lower frequencies. The air in a guitar's cavity resonates with the vibrational modes of the string and soundboard. At low frequencies, which depend on the size of the box, the chamber acts like a Helmholtz resonator, increasing or decreasing the volume of the sound again depending on whether the air in the box moves in phase or out of phase with the strings. When in phase, the sound increases by about 3 decibels. In opposing phase, it decreases about 3 decibels.[5] As a Helmholtz resonator, the air at the opening is vibrating in or out of phase with the air in the box and in or out of phase with the strings. These resonance interactions attenuate or amplify the sound at different frequencies, boosting or damping various harmonic tones. Ultimately, the cavity air vibrations couple to the outside air through the sound hole,[6] though some[which?] variants of the acoustic guitar omit this hole, or have f\displaystyle f holes, like a violin family instrument (a trait found in some electric guitars such as the ES-335 and ES-175 models from Gibson). This coupling is most efficient because here the impedance matching is perfect: it is air pushing air.

A guitar has several sound coupling modes: string to soundboard, soundboard to cavity air, and both soundboard and cavity air to outside air. The back of the guitar also vibrates to some degree, driven by air in the cavity and mechanical coupling to the rest of the guitar. The guitar—as an acoustic system—colors the sound by the way it generates and emphasizes harmonics, and how it couples this energy to the surrounding air (which is ultimately what we perceive as loudness). Improved coupling, however, comes at the expense of decay time, since the string's energy is more efficiently transmitted. Solid body electric guitars (with no soundboard at all) produce very low volume, but tend to have long sustain.

All these complex air coupling interactions, and the resonant properties of the panels themselves, are a key reason that different guitars have different tonal qualities. The sound is a complex mixture of harmonics that give the guitar its distinctive sound.

Main article: Acoustic-electric guitar An Ovation Adamas,[7] whose parabolic shape reduces feedback and increases volume.

Classical gut-string guitars had little projection, and so were unable to displace banjos until innovations increased their volume.

Two important innovations were introduced by the American firm, Martin Guitars. First, Martin introduced steel strings.[disputed – discuss] Second, Martin increased the area of the guitar top; the popularity of Martin's larger "dreadnought" body size amongst acoustic performers is related to the greater sound volume produced. These innovations allowed guitars to compete with and often displace the banjos that had previously dominated jazz bands. The steel-strings increased tension on the neck; for stability, Martin[disputed – discuss] reinforced the neck with a steel truss rod, which became standard in later steel-string guitars.[8]

Many acoustic guitars incorporate rosettes around the sound hole.

An acoustic guitar can be amplified by using various types of pickups or microphones. However, amplification of acoustic guitars had many problems with audio feedback. In the 1960s, Ovation's parabolic bowls dramatically reduced feedback, allowing greater amplification of acoustic guitars.[9] In the 1970s, Ovation developed thinner sound-boards with carbon-based composites laminating a thin layer of birch, in its Adamas model, which has been viewed as one of the most radical designs in the history of acoustic guitars. The Adamas model dissipated the sound-hole of the traditional soundboard among 22 small sound-holes in the upper chamber of the guitar, yielding greater volume and further reducing feedback during amplification.[9] Another method for reducing feedback is fit a rubber or plastic disc into the sound hole.

The most common type of pickups used for acoustic guitar amplification are piezo and magnetic pickups. Piezo pickups are generally mounted under the bridge saddle of the acoustic guitar and can be plugged into a mixer or amplifier. A Piezo pickup made by Baldwin was incorporated in the body of Ovation guitars, rather than attached by drilling through the body;[10] the combination of the Piezo pickup and parabolic ("roundback") body helped Ovation succeed in the market during the 1970s.[9]

Magnetic pickups on acoustic guitars are generally mounted in the sound hole, and are similar to those in electric guitars. An acoustic guitar with pickups for electrical amplification is called an acoustic-electric guitar.

In the 2000s, manufactures introduced new types of pickups to try to amplify the full sound of these instruments. This includes body sensors, and systems that include an internal microphone along with body sensors or under-the-saddle pickups.

Historical and modern acoustic guitars are extremely varied in their design and construction, far more so than electric guitars. Some of the most important varieties are the classical guitar (nylon-stringed), steel-string acoustic guitar and lap steel guitar.

Baroque guitar, c. 1630. Gibson L-3 archtop. Common guitar body shapes: A. Range B. Parlor C. Grand Concert D. Auditorium E. Dreadnought F. Jumbo

Common body shapes for modern acoustic guitars, from smallest to largest:

Range – The smallest body shape, also considered a "mini jumbo", is three-quarters the size of a jumbo shaped guitar. A range shape typically has a rounded back which provides projection and volume for the smaller body.[11] The smaller body and scale length make the range guitar an option for players who struggle with larger body guitars.

Parlor – Parlor guitars have small compact bodies and have been described as “punchy” sounding with a delicate tone.[12] The smaller body makes the parlor a more comfortable option for players who find large body guitars uncomfortable.

Grand Concert – This mid-sized body shape is not as deep as other full-size guitars, but has a full waist. Because of the smaller body, grand concert guitars have a more controlled overtone[13] and are often used for its sound projection when recording.

Auditorium – Similar in dimensions to the dreadnought body shape,[14] but with a much more pronounced waist. The shifting of the waist provides different tones to stand out. The auditorium body shape is a newer body when compared to the other shapes such as dreadnought.

Dreadnought – This is the classic guitar body shape. Used for over 100 years, it is still the most popular body style for acoustic guitars.[15] The body is large and the waist of the guitar is not as pronounced as the auditorium and grand concert bodies. This allows mid-range frequencies to stand out, helping the guitar cut through an ensemble of instruments.

Jumbo – The largest standard guitar body shape found on acoustic guitars. The large body provides more punch and volume,[16] while accenting the “boomy” low end of the guitar.
