Well I think I might know your problem. Your pick-ups. Jerry's Wolf has three single coil pick-ups while your SG has two humbuckers. The difference; well a humbucker has more power more crunch. It play's dirtier, rougher. While a single coil has a thinner HIGHER sound. A Fender Strat has single coils if you don't have a Strat you can buy a fine Standard of $430 from Musiciansfriend.com.
