I bought a couple of '51 P-bass pickups today: a Seymour Duncan Antiquity II and a Quarter Pounder. Mostly it was to see which one sounded better, but I had the idea of putting the Antiquity II in the neck position and, at some other point, putting the Quarter Pounder in the bridge position. Stack knob jazz controls would be needed for this. At this point it's just an idea since I need to see if the QP pole pieces line up properly, but I think it'd work since they're so huge. Has anyone done something like this with their '51 pup bass?
