I just bought my third bass guitar- a fretted Roscoe SKB-3006. The other basses are fretted 4s: Ibanez Lawsuit Fender Jazz copy from pre 1975 and mid 80's Guild Pilot. I've thought about selling one of the other basses, but I just don't want to. I've read many a thread that seems to have players buying and selling basses like they are buying clothes because their old clothes have gone out of style. I just can't do it. I may not use my old basses much (I'll have to wait and see), but I can't see myself ever letting one go. How do you let go?
