I just got my Mark IV out of the pawn shop, It was in there for at least 6 months. So now my amp is stuck on channel one, it bumps up in volume when i switch to rythym 2 but that is it...it does nothing when switching to channel 3 and does nothing with the footswitch. I'm stumped???

Did you check the big dial in back and set it right?

Yes I did. I even opened it up to see if I could see anything wrong but i'm not very good with electronics. I was thinking about maybe spraying some contact cleaner on that wheel thing that the channel switching dial is connected to??
Make sure you use deoxit 5. It is the only thing to use, anything else will ruin the potentiometer.

Never mind I figured out my own issue. It might have helped to not have it on auto RHY 1 lol, well this is my first amp tube amp. so learning experience.
