Talking about Seymour Duncan pickups specifically... On the duncan 4-wire humbuckers, the color codes are as follows... I want to set up a switch to select either side, or both in series. Im starting out with just a simple practice amp and a patch cable. (wanted to check my wiring before hooking anything up) When I connect the green lead to the common wire of the cable, and the red wire to the tip, I still get sound out of both sides of the humbucker. In this case, the south side is louder and more prominent than the north, but the north is still making noise (even though the white and black wires are unconnected to anything) The opposite happens if I connect the black and white leads to the patch cable....the north is louder but the south still 'picks up' noise. At first I thought something was wrong with the pickup, so I tried another one I had....same issue. (and these are both brand new pickups) What is going on? I really want to be able to get three options out of the humbucker....the north, the south, or everything in series for full humbucker sound. What am I missing?
