So I picked up a 1973 SG Custom walnut finish last week. Great condition but of course someone along the way swapped out the pups with some unpotted pups that look to be japanese. No markings but god the squeal. Neck is the only pup I can get a decent sound out of. I went into it knowing the pups had been swapped but I seen what it could be and having such a great acoustical sound not even being plugged in I wasn't shy. Sooo if there is any SG custom owners here with some ideas on which set and what would make a great middle pickup I would appreciate it.
