What would be involved in taking a set of J pickups and putting them in a single pickup housing to make a JJ pickup (similar to Roscoe Beck, Aero, Fodera, etc...). Would I have to mount them on a single plate? Would I have to put some sort of insulator between the coils (plastic/wax...)? Seems like a fairly simple idea as long as the routes in the bass fit. A cover might be hard to find, but i know where they make wood covers that would be nice. Ideas?
