I don't worry about taking my sixties and seventies Birds out for rehearsals and gigs too much. I always think: Anything these instruments experience with me (ok, I would probably not let the drummer drum part of his drum solo on a vintage bass like I let him do it in the eighties with my Kramer alu neck, it was part of our stage act, always sounded great, like Mark King gone mad) is probably nothing compared to the ordeals they have gone through with series of pre-owners. Basses have a certain karma, they either break (and if they do, it can happen in the living room) or they don't. I've knocked the headstock of my well-repaired Reverse IV once badly, but it held fast, and the not so well repaired one of my Embassy came off without outside influence while it was placed in a (not neck hanging) stand for months.
