Cleaning dirty knobs.
Oh behave....lol
I have an old Marshall Valvestate practice amp and it's playing up. A couple of the knobs on the front crackle and cut out when I turn them. I've been told the switches are dirty and I just need to take them out and clean them, but I have absolutely no idea how to do this. Can anyone tell me what I need to do? Can I attempt this myself, am I likely to fuck up my amp if I do it wrong?
