This one is a February 1985 Bich 8 string Supreme-Neal Moser said only approx 20 were ever made
Koa Wings,Maple neck,Ebony Fretboard,Bound neck and heastock.
The original Bridge was Les Paul type then replaced it with Badass 1. (Lower photo)

Bich Bass might have only a short scale for the unique body shape.
The body grows too big when making it to a long scale.
The plastic panels were changed from 3ply to 1ply in mid '80's.

Thanks Lorne!
