Rehearsed with it plugged into the PA. I am super impressed. I'm sure a couple 15" speakers helped. Really nice fat cleans. Works well with pedals...set it just like I'd set an amp and step on the boost, or get overdrive from the pedal. What it is NOT, is a dirtbox for cranked sounds at low volume. One has to think of it like an amp. I would be fine with gigging it.
