I have had this unit for over a year now and I really like it. However, last night the right most foot switch (channel 3) stopped working. The LED seems to briefly come on when power is applied just like the other LEDs do. Also, when i reset the unit to factory preset it seems to function. Factory reset is done by holding channels one and three down and applying power. This resets the unit, but I am still unable to switch to channel three. Of course, I am outside the warranty period. I am holding out that I did something stupid that is correctable. I plan on sending the unit for repair but I thought posting on TB might help. I don't NEED all three channels, but I do LIKE them.
