I've had the RP200A for a couple of years now. It's always worked well but recently it's started cutting out while I'm playing. Sometimes it starts messing up immediately, other times it starts after I've been playing for a while. When it doesn't go completely silent, it starts making scratching and popping sounds, like if you are touching a cable around the jack on a guitar with the amp on. Sometimes I can cure the problem by stepping on the unit near the back (above the jacks). Has anyone had this problem before? Help!

It is most likely that a wire came loose. Open it up and check the wires going to the jacks on the back.
