I have 57 Classics in mine. I got back and forth with it, largely based on what I've been playing. If I've been playing the Les Paul or PRS DGT a lot, it sounds fine. Then I play the Strat on the neck, and the Les Paul on the neck sounds like it has a blanket over the amp. It prefers cleaner amps too. It sounds WAY better on the AC30 or Deluxe Reverb than my Marshall. It still sounds good with the Marshall, but there is a sparkle to it through a cooking amp set for clean with a little hair to the tone that is just magical.
