I'm contemplating downsizing my 4x10 to a 2 1x12 mini rig powered by something like 600 watts or so. I've used a 2x15 with only 450 watts going into it in the past and have been satisfied. Think that I'll be okay? I'm only going up against a drummer and a guitarist that uses a 212 tube combo who's aware that his amp has a volume knob.
