Zappa about Les Paul
Talking about Paul Buff in The Real Frank Zappa Book (1989), FZ mentions Les Paul: "He built his own homemade, five-track, half-inch tape recorder -- at a time when the standard in the industry was mono. (I think only Les Paul had an eight-track then. Buff was able to overdub the same way Les Paul could, but in a more primitive manner.)"
