My neck pickup went "out" recently and I'm trying to find out if it's truly the pickup is "dead" or maybe my switch is bad? I have a three-way switch between two humbuckers and neck position has very quiet clean/clippy sound when switched to it, the middle has full sound from the treble pickup although should be both I can't really tell a difference between middle and treble selection, but maybe it works properly there. Can anyone tell me how/if/what/why/can a pickup go out or does this just sound like a switch problem?
