I own a mesa F-50 head that I am playing through an Avatar 4x12 with vintage 30s. When I would jam with my band channel 2 sounded fine possibly because it was really loud with everyone playing. We started recording and found that it is a very grainy overdrive/distortion. Is this an amp issue? What amp could I be looking for that would have a nice smooth but capable distortion with a good clean as well?
