I've really looked all over and can't find a diagram, so here's what I'm doing. Ripped the active pre out of my Epi T-Bird Pro. Too scooped, don't like it, blah blah, anyway... I have 4 holes to fill and want to do this: top/front = neck vol top/back = bridge vol bottom/front = master tone bottom/back = 3-way selector Is this possible? I think I've kind of pieced together how to do this by looking at the Seymour Duncan site and combining the Passive Soap diagram w/ general Gibson 2x2/3-way sort of thing. Am I wrong? Might be... Also wondering what the general consensus is about 500k vs 250k pots. Pickups are the Duncan Designs that came w/ the bass.
