I have a 1990 RG 550 and for years had a
PAF Pro in the neck, and a
Super Distortion in the bridge. Single coil was from an American Standard Strat, I believe a 1988 model.
Good sound with those, very happy for a long time.
I now have a set of Evolutions and an HS-2 wired for single coil in the middle and it's very sweet.
Smooth distortion, sweet when clean, nice "honk" from the single coil and split humbuckers, and it almost feels like it plays itself those Evos are so responsive.
