Excellent little amp. Glad I went for a real AC powered, 6" speaker, 10 WATT amplifier. So it doesn't fit in a lunchbox or on your desktop. I wasn't planing on doing any gigs in the park for friends. The distortion is excellent. It really has a crunch and it's LOUD. Yeah, you may want to add a couple of external effects. Then you probably already have some anyway.
