My SG came with 4 conductor 57 Classics. I tore out the PCB and wired it using the 50's wiring scheme. I wired both pickups as follows: Black & Bare = Ground Green & White = Together Red = Hot / Volume Pot Input In the middle position if the volumes are set the same it is very thin and quiet compared to each pickup by themselves which seems to be a phase issue. Shouldn't the pickups be in-phase?!?!
