I have a used Line 6 MM4 pedal. Three of the four switches work. The far most left switch does not. I was going to fix it myself but I just don\'t have the time right now. There is a bit of a volume drop with this pedal. I did start the mod for the volume drop I just used the wrong resistor. This would be an easy mod. The same thing goes for the far most switch not working. It\'s probably an easy fix I just don\'t have the time to mess with it. Other than the pedal works fine and all the other switches and knobs work. I replaced the original foot switches with new ones (The ones that come factory on this pedal tend to fail) and I also replaced the power jack. I replaced the far most led too because I originally thought that it was just the led that had gone but it wasn\'t.
