hey ug, lately ive been hearing slight feedback everytime i hit a string or power chord when my amp is cranked and when im using my epiphone sg. like the feedback would like go on half a second then it stops. but the louder it is, the longer the feedback is. btw my amp is a spider valve 112, & i dont hear slight feedback on any of my other guitars. plz help me.
Move away from your amp.
i tried that, that didnt work either.... and im like 5 feet away from my amp too.
