Today on a quite big gig, the tuner knob didn't work all of a sudden, no matter how long or hard I srtepped on it. Switching off and on the pedal doesn't change anything. I read in some other entries according this problem, saying that a factory reset will not help. I did a lot of work on two complete setups, therefore I'm hesitating to do this anyhow. What could cause this malfunction? Is there any 'dirty' trick to repair it, or must I send the unit back?

That worked also with my M13. Thank you very much. I was about sending the pedal back when I found this one.
