Not Bad

This amp has got some good sounds. It's very rock based, so I wouldn't recommend it for any lighter players (jazz etc.) I've been having a few issues with it actually working without going all static on me but to be fair it is an old amp so I guess it can't be helped.

Boring Workhorse

Got this amp when I was 16 because it was loud and had effects. Also cheap!

I'm 24 now and it's the only amp I've ever used and owned, but now that I have effects pedals, the "clean tones" are kinda boring. I have taken this thing on tour extensively, works in any size room, I never have any trouble hearing it, and it can take a beating, but if it breaks I probably wouldn't replace it. In an ideal world I'd get an Orange or Aguilar combo, but again, $$$.
