I just picked up a stunning 1985 Repro Private Stock. But someone had changed the wiring. Installed in a toggle switch that is a direct rear humbucker switch. In the off position the usual rear HB position (1) is rear single coil. Pos 2 is outside coils parallel, Pos 3 is inner coils parallel, pos 4 neck single, pos 5 neck HB. The tone pot is a push pull sweetswitch. How hard would it be to change pos 3 to be inner coils in series (warm strat out of phase sound)? How was the old power out of phase achieved? I love that too. Would that be possible? Most important for me is to get the pos 3 in series if possible. Quick pic.
