Someone else reported clicking/switching noises that went away when the foot-switch was unplugged. I have the same problem. I believe that it is the 9-pin connector in the foot-switch. Mine has a bad contact with the EQ switch and will often refuse to switch. Then, the other day, all these switching noises while I was playing, cutting sound on and off. I am convinced it is the connector pin in the foot-switch.......COMMENTS?
