Here I am, once again. The middle switch problem actually seemed to disappear on its own after a little while. The unit eventually worked fine until last Saturday: I was gigging and, after a few songs without issues, the LEFT switch wouldn't turn on (again: in April it was the middle one). I had to dump the PF for the rest of the show. Yesterday I was determined to understand what was going on; as soon as I powered the unit, it was working perfectly like right out of the box. But then, this morning the weirdo started to go its own way, left switch engages randomly.
I tried to get back to the previous versions but it didn't work. I'm a bit downhearted since I don't know what's going on, the pedal has been working just fine for 2 years: Any suggestions are really appreciated. Thanks for the support!
