Ok everytime I have a decent amount of overdrive on the amp starts to buzz like crazy. If i switch to the middle pickup it gets quiter, I guess it's because it's low output? Anyways all my cables are in good condition. I use a jeckyl and hyde overdrive but even if i overdrive the amp by itself it still does that. Can someone tell me what's the problem?
How old are the valves?
around 9 months
