hey i have a B52 AT100 and i need help. every time i switch to od1 or od2 i get an insane overpowering amount of static.

any help?)
thank you

Not sure really. Not too familiar with the B52s so bump for ya. It may be bad preamp tube. Replace them one by one until you find it. There may be a particular preamp slot designatied for OD2 so if so, that would be a logical first place to look. I can't think of anything else unless it is the circuitry for OD2?
Make sure your cables and guitar(s) are grounded properly and try another cable if possible. Could also be a tube as mentioned, but try the simple/cheap stuff first.
