Brian May from Queen used AC30s via a boost pedal. Not too many examples of the AC30 sound, but there's one, though perhaps not an ideal one, given that May's guitar/PU combination was unique, etc. I Understand the Beatles used them a lot.
I've played through an AC30 a couple of times - a soft but glassy sound (typivcally clean 'class A' springiness), but distorted tones alone (without any boost pedal) I don't know.
