. . "The Warr guitar is an American-made \"touch\" guitar, a type of instrument that combines both bass and melodic strings on a single fretboard. It is related to the Chapman Stick, another two-handed tapping instrument. The Warr Guitar is designed for either two-handed tapping or strumming. Warr Guitars have between seven and 14 strings.Perhaps the best known Warr Guitar player is Trey Gunn, formerly of the progressive rock band King Crimson."@en .
