I've got the MG101CFX with the PEDL 90010, and the CLEAN/CRUNCH isn't working. It's clicking like it's working, and the OVERDRIVE button works. The amp also changes CLEAN and CRUNCH by pushing the button on the amp. Any ideas?
If your amplifier is still under warranty we would recommend taking it back to the dealer so they can check it over for you. If it was working before you can try re setting the amplfiier, the handbook describes how to do this.
