Electric violins

An electric violin is a violin equipped with an electric signal output of its sound, and is generally considered to be a specially constructed instrument which can either be:
-an electro-acoustic violin capable of producing both acoustic sound and electric signal ;
-an electric violin capable of producing only electric signal.
To be effective as an acoustic violin, electro-acoustic violins retain much of the resonating body of the violin, often looking very much like, sometimes even identical to, an acoustic violin or fiddle. They are often varnished with bright colours and made from alternative materials to wood. The first specially built electric violins date back to the late 1930s and were made by Victor Pfeil, Oskar Vierling, George Eisenberg, Benjamin Miessner, George Beauchamp, Hugo Benioff and Fredray Kislingbury.
Since electric violins do not rely on string tension and resonance to amplify their sound they can have more strings. For example five stringed electric violins are available from several manufacturers, and a seven string electric violin (with three lower strings encompassing the cello's range) is available. The majority of the first electric violinists were musicians playing jazz and popular music.
