Our rehearsal room has these now instead of their previous Ampeg SVT450s. I`ve used these Peaveys a few times and not been that impressed however last night for some reason I happened on a sound that was really good, sounded a bit GK-like being crisp and clear but with good defined low-end, I was impressed, helped make the band sound great.
I`m not going to look at buying one as I love my Ashdown amps but I suppose the moral of this story is that sometimes a good sound is in there somewhere, you just have to persist/work at finding it.
