I have an almost new Genz Benz Shuttle 6.2 and I have two Eden EX112 cabs that are 8 ohms each. I have used the head a few times now at practice and one gig and I have noticed that no matter what the "Peak" light is flashing almost constantly at any volume around half way or higher. The gain or gain volume has never gone over half way. Does anyone else have this issue? Is it common? Is it something to worry about? It doesn't fart out or clip at all. What could I be doing wrong?
