Well, the warbley sound came back at last nights practice. So, I switch presets and back, it went away.. then in the middle of the ZZ Top 'La Grange' solo, where there are they high artificial harmonics going on.. the amp just turned off and then turned back on, with half lights & then off again.. then I smelled a strong burnt plastic smell and I unplugged it from the wall and a small stream of smoke came out the back :(
Still a RMA issue? w/90 per hr and parts... in 3 hrs, I could buy a new amp?
