All my basses have Schaller straplocks, does that count?
My Fender, more by virtue of being my main (and oft mistreated) gigging bass has it's fair share of replacement parts, and they're all Switchcraft or the like. Just as parts failed, especially the jack socket as someone mentioned. That too the pickguard out when it went, so the new pickguard is the same, only 5 ply rather than 3. Only the pup is an 'upgrade' for the sake of it, the only thing I've changed by choice rather than repair.
