I own a marshall G30R CD model, and when ever I turn up the volume on the distortied channel, it pops really loud. Also when I hit the distortion, it does this really funny buzzing sound kinda like a shocking sound. It's not feedback though, and I've only had the amp for about a year now. I thought it might just need to be taken apart and cleaned, but today I took off the volume knob and I think it has a short in it, coz when I barely even touched it without the knob it poped. Can anyone hear tell me what it could be, and what I should do?

I have never failed to fail.:mad:
