Hopefully a simple wiring question

[Slartibartfarst42]

To me, everything to do with wiring is difficult and that's why a band mate always installs my pickups but this time I want something different. When I was looking at a PRS Bernie Marsden guitar I found a video of him on You Tube going over its features and one of the features he was going on about (which never made it to the production version I don't think) was that while the pickups were normal in positions 1 and 3, when he went to the middle position, they went out of phase to give him a Peter Green sound. I really liked the idea of that as the middle position isn't one I use a lot but I think I could use this option. So how easy is it to do this and what would have to be done to the wiring?

As usual with guitar players, the Peter Green out of phase thing has given rise to much discussion and a fair number of myths and legends.  Should you reverse the magnet?  Reverse the winding of the coils?  Turn your neck pickup round so the screw polepieces face the bridge (which doesn't actually affect the phase relationship at all...)?

Bottom line is, simplest way to do it, if you have a regular set of BKP humbuckers with 4-conductor wiring:

Swap around the connections of the red and black wires, on one of the pickups only.  Everything else stays as it is.

It works best if the two pickups are fairly well-matched in output, and if you have two volume controls, you'll find you can vary the out-of-phase effect by balancing the volume of the pickups.

This.  If you can, use a push-pull pot, or a DPDT toggle so you still have the regular sound in addition to the out-of-phase  sound.
