  (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."

The Pros and Cons of Private Acoustic Guitar Lessons

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.

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]

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]

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".
