This is a guitar that I built with my father and brother when I was an undergraduate. The body is made of maple, mahogany, and oak, making it the heaviest guitar ever. The necks were purchased from Warmouth. The guitar and bass each have separate outputs, requiring separate amplifiers. It was built so that I could play the guitar neck with my left hand, and the bass neck with my right. Each pickup has a tone and a volume knob.
