I have a '78 Japanese Black Beauty copy with 3 uncovered double-cream humbuckers, and the bridge pickup is microphonic. I might be interested in replacing that one or all three, but I'm having a hard time finding a pickup maker who does aged/relic'd uncovered pickups. Lots of guys do the aged chrome cover thing, but I'd like to preserve the '70s look here. Outside of buying a bunch of old DiMarzios on Ebay - who does good aged bobbins? Thanks.
