The Vox Guitar Organ was expected to revolutionize music. It did not. Wikipedia explains, "In 1966, Vox introduced the revolutionary but problematic Guitar Organ, a Phantom VI guitar with internal organ electronics. John Lennon was given one in a bid to secure an endorsement, though this never panned out. According to Up-Tight: the Velvet Underground Story, Brian Jones of the Rolling Stones also tried one; when asked by the Velvets if it "worked", his answer was negative."
