Hey I have a Sunn sonaro I've been using with guitar for some time now. Great amp but not entirely consistent despite that it was recently serviced. That being said I push it pretty hard sometimes. Anyways today while jamming it started basically what sounded like it was gating itself.... if I didn't pick hard enough the amp would not engage, this happened through my board and directly into the amp....
Kinda hoping it just solves itself.... I also happen to have good amp tech connection i can take her too, but was hoping someone might know what was causing this as not only am I entrigued but just really bummed that my favourite amp isn't at its best.
