Does what it does for the low price. Cannot do clean channel or just very faint. Dirty channel isn't a very clear distortion either. But good enough for classes and small jam with friends. Props for Bluetooth reliability. Can have a track playing along on Spotify as a background while UG rolling. Props for 3.5mm headphone jack as well. Not disturbing roommate anymore while he's asleep. No effects like echo, delay, AI backtrack, etc, but for a small fraction of that sparky thing I'd settle =)
