It's probably the same 30 watt battery amp they put in the BA330. Loved the mixer/effects/stereo link feature/speaker combo. While a nice concept it lacked any punch or power and I sent mine back. Good only for some mellow acoustic stuff. Had they put a solid 250 watt or so stereo amp in there I would of bought two for a true stereo setup. I think for really small stuff you re on the right track with a regular small keyboard amp or active pa speaker.
