Hey, I own an epiphone 1966 Limited Edition Reissue SG with a batwing pickgaurd. I am thinking about purchasing new pickups and I had a few question about the wiring. First of all I would like to be able to have push pull pots to use for coil splitting and an in/out of phase switch, so does anyone know it the push pull pots will fit in the sg body since it is so thin? Next, if I were to add coil splits, I assume I would need to shield the guitar and pickgaurd; when I do this how would I wire the ground wire to everything that needs it as well as the shielding?
