I had one with a serious sheilding/grounding issue, where it buzzed and picked up various radio signals and electrical sounds when it was next to high voltage power lines, which for me was almost everywhere I had to use it. May have been a dud.
That being said it was an ok practice amp. Might be ok at a gig with PA support, or a light handed drummer. The effects were useless live, maybe fun to play with at home. Found it pretty heavy for the size and what you could get out of it.
Depending on what you are planning on paying for it, I would look at an Ampeg SVT210AV with some class D microhead. Much more portable, and probably a better sound IMHO.
That or look at the newer Portaflex head/cab combos. Heard good things about those.
