An electric violin is a violin equipped with an electronic output of its sound. The term most properly refers to an instrument intentionally made to be electrified with built-in pickups, usually with a solid body. It can also refer to a 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 and Vega sold electric violins in the 1930s and 1940s; Fender produced a small number of electric violins in the late 1950s. There has been a great deal more commercial success of well known manufacturers of electric violins since the 1990 for both well known, established companies and new makers too.
Acoustic violins may be used with an add-on piezoelectric bridge or body pickup, or a magnetic pickup attached to the fingerboard end. Alternatively, an electrodynamic pickup can be installed under an acoustic violin's fingerboard avoiding interference with any tone-producing parts of the violin, and therefore keeping its acoustic resonances and tone intact.
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. Lately, materials such as kevlar, glass and carbon fibres, are used in the build process.
