I had a Super Distortion in an RG, sounded great. The Tone Zone is probably the most popular one around here. Of course a lot of folks here use the Evolution. Another one I like that's less popular is the Super 3. Hard to go wrong with any of them.
They are really the only pickup I've heard beyond the PAF7 and PSND. Just want to try out different ones. I'm looking at using the 220B as a test subject to figure out what I like. I keep changing my mind so I never seem to get anywhere.
