Hey guys, I'm having an issue with my Supersonic and was hoping someone could help me diagnose it. I keep experiencing a loud noise when I play (I mean, other than my playing itself lol) that I can only describe as a "static-y" sound. It seems to get worse the louder or more aggressive I play but I don't think that is always the case. The interesting thing is that it doesn't do it on the dirty channel, only the clean channel. I'm assuming it's tube-related, just because that seems to always be the case but does what I've described point to any particular tube as the culprit? I have one new 12AX7 and it would be awesome if I could narrow it down, swap out the bad tube, and be done with it. Any suggestions?
