    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?

    The dirty channel might be doing the same thing, except you don't notice it.

    I doubt it's a tube issue, since both your channels use the same tubes.

    Try swapping your new 12ax7 in place of each 12ax7 and you’ll know pretty quickly if you have a bad tube if and when the noise goes away. You can pull and replace the tubes with the amp on and standby off.

    Just so I'm clear, there is no risk to me or the amp if I leave the amp on, switch to standby mode, swap out a tube, then switch out of standby mode and continue playing?

    You should shut the amp completely off. Standby switches only cut the high voltage and not the tube heaters. While nothing should *technically* go wrong pulling the tube with the heaters running, just shut it off.

    This is a bit left field but the way I play my finger tips rub the pickguard. Most of my fender style guitars do make a static noise if i don't pull the finger tips off the pickguard.

    You said it gets worse as you play more energetically that might be why?

    I've never had a problem swapping preamp tubes with amp in standby but perhaps I am lucky, and I can see why it might be safer to shut it off. Only downside is waiting a little for the amp to warm up with each swap.

    Speaking of which, the greatest risk might be burned fingers. If the tube is hot use an oven mitt or something else insulating to grasp it.

    ROOSTER, in order to check this situation of static discharge that Kiwi describes; rub your fingers across the pickguard...making and breaking contact....to see if this is your problem. If so, polishing the pickguard will cure the problem. If not....proceed. Ime, it is best to eliminate the simple stuff first.
