Hey guys,
I just got my Mark IV back from Mesa like 2-3 months ago. everything was working fine then a couple days ago the volume would drop a little bit after about 5 minutes of playing but it still sounded good so I didnt worry about it. Tonight I was playing, the volume dropped then it started sounding like a busted distortion pedal. I was hoping it was just the tubes but I swapped all of them out with known good ones and no difference. I created an RMA with Mesa but I really dont want to ship it out. Any recommendations of what to check? Im probably not going to fool with it too much unless its something obvious and simple which after looking at the internals I dont think exists
