I have a 1991 Fender Custom Shop 40th Anniversary Precision Bass, #4 of 400. Does anyone know about how much these are going for? Looking at a thread from 5-6 years ago it looks to be @ $1700 in great condition, but wondering if they have gone up since then. It's in excellent condition with the original case, custom shop paperwork, and tags from the original sale. Not sure if I'm going to sell, but just wondering if anyone could help me find more information. Thanks.
