In an interview, Bill Wyman said "I also played a see-through Plexiglass Fender Mustang for a while..." I've been trying to find a photography of the instrument he mentions, but I can't. I know of an Ampeg Dan Armstrong plexiglass electric bass and there are photos of him playing it, so it makes me doubt a lot. Does anyone know if that plexiglass Mustang has ever existed or if he just told wrong? And when was the Dan Armstrong plexiglass bass introduced? Thank you!
