This post is a question about a Gibson Firebird guitar, not a bass, but hopefully someone will have an answer... My brother has a 1982 Gibson Firebird (reverse) with 2 pickups that always seemed to have an output problem...or actually lack of output problem. It has had the stock pickups, Duncan Hot Minis, and custom made "Four Seasons" pickups (from Holland). The guitar has always sounder very good, but has always had much lower output then any of his other guitars, including similar Gibson Firebirds. As far as we can tell, all of the wiring is stock and though one of the volume pots that stopped working was switched out, I replaced it with a new Gibson pot of the same value. Does anyone have any idea of why the output of this particular guitar would be so much lower then other similar guitars?
