I was going to start a new thread for this picture, thinking I had stumbled on a picture of some weird Triumph prototype, but this thread made me realize it is probably a (Japanese?) copy:
This is Jaki Liebezeit, best known as the drummer for Can. I scanned the picture from
The Can Book by Pascal Bussy - I just happened to dig this book out of my storage space - probably haven't looked at it since 2002, a time when I was totally unaware of the Les Paul basses. Imagine my surprise when I see a 22-fretter with smaller pickups! After reading this thread and looking again at the picture I realized that the headstock is not visible.
