If you plug that bad boy to power supply it works like a charm. Loud, chunky, and crazy cool. But if you decide to go out with it busking, or just walking it losts all of it's pros. If you hit strings to hard it's going to struggle, if you make it louder than barely hearable it struggles, if you have gain higher than 6 o'clock it's going to struggle, no matter how quiet it is. I still love this miniamp, but I wanted more than barely hearable. I'm not mad, I'm just disappointed
