So, this has been an on and off problem with it for about a month now. The amp ( a randall rg50tc tube 50watt combo) randomly starts picking up radio stations and static ( not just normal feed back, its as loud as the guitar) in little bursts. So like usual when trying to make something work i gave it a wack, and it stoped! but usually 40-60 seconds after i give it a wack the static starts up again. I'll try to get some soundclips if they would help at all. Anybody had any similar experiences? Is it easily home fixable or would it be easier to just take it into a tech?
I'm pretty confident that is an overly microphonic preamp tube. Buy a new one and swap it around until you find the culprit.
