Electric violin

An electric violin is a violin equipped with an electronic output of its sound. The term most properly refers to an instrument purposely made to be electrified with built-in pickups, usually with a solid body. It can also refer to a standard violin fitted with an electric pickup of some type, although "amplified violin" or "electro-acoustic violin" are more accurate in that case.

Electrically amplified violins have been used in one form or another since the 1920s; jazz and blues artist Stuff Smith is generally credited as being one of the first performers to adapt pickups and amplifiers to violins. The Electro Stringed Instrument Corporation, National Valco and Vega attempted to sell electric violins in the 1930s and 1940s; Fender produced a small number of electric violins in the late 1950s.

Acoustic violins may be used with an add-on piezoelectric bridge or body pickup. To avoid feedback from the resonances of the hollow body under high amplification on stage, many instruments have a solid body instead. The timbre (tone color) of a standard unamplified violin is due in large part to these resonances, however, so depending on how the signal is picked up, an electric violin may have a "rawer" or "sharper" sound than an acoustic instrument. This raw sound is often preferred in rock, pop, and some avant-garde genres. Several "semi-hollow" designs exist, containing a sealed but hollow resonating chamber that provides some approximation of acoustic violin sound while reducing susceptibility to feedback.

Solid-body electric violins typically have a non-traditional, minimalistic design to keep weight down since they are manufactured from wood. Lately, materials such as kevlar, glass and carbon fibres, are used in the build process.
They are often seen as "experimental" instruments, being less established than electric guitar or bass. Hence, there are many variations on the standard design, such as frets, extra strings, machine heads, "baritone" strings that sound an octave lower than normal, and sympathetic strings.

Acoustic 5-string violins exist, but it is much more common for an electric violin to have 5, 6 or 7 strings than an acoustic instrument. The typical solid body also accommodates the extra tension caused by more strings without stressing the instrument too much. The extra strings are usually a low C string for 5-strings, a low C and low F for 6, and a low C, F and B♭ for 7.

Electric violin signals usually pass through electronic processing, in the same way as an electric guitar, to achieve a desired sound. This could include delay, reverb, chorus, distortion, or other effects.
