Musical instrument maker Luke Jones has invented a curious double length guitar which is an adaptation of ideas taken from Glenn Branca, Bart Hopkin and Fred Frith.
Glenn Branca a highly influential avant-garde composer and guitarist known for his use of volume, alternative guitar tunings, repetition, droning, and the harmonic series, at one point in his career, created a double body guitar (seen here).
The double length neck guitar is able to produce either singular or double sounding harmonics in that the string length beyond the slide of the first neck only produces harmonics (which are then amplified by the pickups at that end of the guitar). In the following video Luke demonstrates his sweet sounding Harmonic Guitar.
