Acquired this combo, but has some issues. It sat unused for probably 3 years before I tried it out. It pops and when you look at it funny. The pots are dirty, fuzz and noise when turning them. If I tap the head, it pops very loud.
What should I do? I am trying to get my jam room set up. It's a sweet rig, but I may have to sell it, if I don't get it working by myself.
Thanks in advance.
