P90 wiring mod request for SG Classic?

FRETCOM · May 18th, 2008, 09:37 AM

Hello tdpri,

My apologies if this has been covered somewhere else previously or if I am posting to an in-correct forum. I am looking to find a wiring mod schematic for my Gibson SG classic with two P90's.

I am hoping to find one that will show me how to take one of my tone controls and replace it with a push/pull pot that when pulled out puts the two P90's in series (instead of parallel). And replace the other tone control with a push/pull pot that when pulled out puts the two P90's out of phase. I am looking to maximize the tonal options with this great guitar.

Any capacitor upgrades or suggestions are also welcomed.

Any friendly feedback or direction is appreciated. Thank you !!!

Regards,
fretcom

Do you have THREE-conductor P90s? Because, if you have the vintage braided-shield style leads, when you put those pickups in series or out of phase, it puts the entire length of that lead and all the metal parts of the pickup (baseplate, magnets, polepieces, mounting screws) on the HOT side of the circuit. AND, you'll have to insulate the entire length of it, so that you don't get an output-killing short to ground in the control cavity. No arcs and sparks, but MUCH potential for either NO OUTPUT or unpleasant noises.
