amazing (AMAZING) size and weight. didn't get to play with the tone controls much, pretty much had everything flat and didn't drive it very hard. played with full band though an SWR 2x10 for about an hour (it's what was available) cut through fine, but sounded too "solid-statey" and sterile for my tastes. most frequencies represented well though. overall, i MUCH prefer my ashdown abm500 tone. *shrug* but man --- what a dinky amp!
