Unfortunately, the amp went out on me during a gig. I play in an acoustic duo, so I'm by no means pushing the amp. It would stay out for approx. 5 seconds, then kick back on. I couldn't tell from the literature if the amp had a protection circuit (similar to the Ampeg PF series). Regardless, the volume was extremely low, so this shouldn't have happened. Its a shame - when it did work, it sounded just fine.
