Like semi-acoustic guitars, they often have f-shaped sound holes. The content you requested has been removed.
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. 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. 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. 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 Gibson Les Paul.
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 s, he experimented with "locking" nuts and bridges that prevent the guitar from losing tuning, even under heavy vibrato bar use.
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. 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. The signal passes through the tone and volume circuits to the output jack, and through a cable to an amplifier.
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. The most common source is or 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.
Double-coil or " humbucker " pickups were invented as a way to reduce or counter the unwanted ambient hum sounds known as 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 While the scale length of the Les Paul is often described as 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. 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. 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. 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 s, designers began to use exotic man-made materials such as aircraft-grade aluminum , carbon fiber , and ebonol. 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.
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. 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. 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.
Modern electric guitars most commonly have two or three magnetic pickups. Identical pickups produce different tones depending on location between the neck and bridge. Bridge pickups produce a bright or trebly timbre, and neck pickups are warmer [ when defined as? The type of pickup also affects tone. Dual-coil pickups sound warm, thick, perhaps even muddy [ citation needed ] ; single-coil pickups sound clear, bright, perhaps even biting [ citation needed ]. Guitars don't require a uniform pickup type: Some guitars have a 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 switch selects between the outputs of individual pickups or some combination; two-pickup guitars have three-way switches, and three-pickup guitars have five-way switches.
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 [ citation needed ].
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 [ vague ] 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 a low-pass filter 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 The strings fitted to the guitar also have an influence on tone.
Rock musicians often [ when? Steel, nickel, and cobalt are common string materials, and each gives a slightly different tone color. The solid-body electric guitar does not produce enough sound for an audience to hear it in a performance setting unless it's electronically amplified—plugged into an amplifier , mixing console , or PA. Guitar amplifier design uses a different approach than 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.
In contrast, most guitar amplifiers provide tonal coloration and overdrive or distortion of various types. A common tonal coloration sought by guitarists is rolling off some of the high frequencies. Guitarists in some musical genres e. 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.
Guitar amplifiers generally incorporate at least a few effects , the most basic being tone controls for bass and treble. There may be some form of "overdrive" control, where the preamplifier's output is increased to the point where the amplitude overloads the input of the power amplifier stage, causing clipping. In the s, 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.
Among the first actual on-board effects were a tremolo system sometimes incorrectly labeled and marketed as vibrato , or a mechanical spring reverb unit. In the s, guitar amps often contain multiple effects, such as distortion , chorus, flanger, phaser, or octave shift. Recent amplifiers may include digital technology similar to effects pedals, up to the ability to model or emulate a variety of classic amplifiers. Some modeling systems also emulate the tonal characteristics of different speaker configurations, cabinets, and microphones.
Nearly all amp and speaker cabinet modeling is done digitally, using computer techniques e. In the s, 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.
