Just the finish, of course. I have the Fender signature Noel Redding Jazz bass and I like it a lot (although I'm more of a P bass guy if we're talking Fenders and, in fact, I haven't played a solid body bass since I was a teenager- but I digress). Would it be crazy to sand the finish off the neck? I just love the feel of a Fender neck that's been rubbed smooth by years of playing. I know it would affect the collectability, but how collectable is it anyway, really? Anybody ever do this?
