The first one I had was an issue. The second one I had was great. The tone was the best I've ever heard out of any amp I've played such as Marshall, Orange, Vox, Egnator, and Fender. I paid an extra $20 for a warranty for the piece of mind the amp wouldn't have any problems for the first year I had it just to be safe. I believe the amp would of been perfectly fine as most of them do which is why they've been out for years, but not many used ones on the market. But I'd rather have an amp that I can turn up to the sweet spot without making the family so upset. Its a great gig amp and for cutting through the loudest of drummers, just not so great when just jamming to tracks at home.
