Hey, i was wondering what pickups i could toss in my 1974 sg iii without any heavy modifications. It has 2 single coil pickups that are the physical size of humbuckers, but i do not know much about pickup replacements and i wanted to know if anyone knew the restrictions on the pickups i could get that wouldn't decrease the value if i decided to keep the org. pickups in a box under my bed incase someone wanted to use them instead for its vintage value.
