I had one for a while that I traded away for a Traynor YCV-40...which I like a lot better. The Peavey had more gain available on the dirt channel and the cleans were nice (not as good as the Traynor, in my opinion). With a simple OD pedal, I had lots of different overdrive/distortion tones.
The "problem" I had with mine was tube rattle. Now I don't know if it was something with the amp design, or just bad tubes, but it drove me nuts. Shortly after I started hearing this rattle in one of the EL84s, I bought a new quad of JJs from that site that specializes in these tubes. I even called the guy and spoke with him about the rattle. So, new tubes in...fine...for a while. Then one of 'em starts to rattle again.
I never gigged or rehearsed with this amp...it just sat in my music room in my climate controlled basement. This experience has turned me off of EL84 combo amps, but I guess it is possible that it something with the design layout of the amp. There are sure a hell of a lot happy Classic 30 owners out there, and there are a lot of EL84 powered amps being built too, so maybe my experience was simply a fluke.
I'm sure this was no help at all, but there it is...good luck!
