Im feeling like my ampeg svt 410hlf is getting a distorted tone way before it should. Im pretty sure my ears arnt getting worse, and its certainly not feeling or playing as loud as it used to on the sameish settings playing vs the same guitar rigs. I have to ask the guys to quiet down their rigs to a level that they are saying is way less than they used to play at. Im running it through a recently re-tubed mesa 400. What could some possible problems/solutions be? And price range?
