I bought a used M5 recently. It seems to work fine except for the following scenario:
When I press and hold the 2nd footswitch ("Tap" button - pressing lightly with a finger) to activate "Tuner" mode, the pedal immediately powers off and then reboots.
I'm powering the pedal with an adapter that matches specs. I sprayed the power jack and the footswitch with contact cleaner, but no change.
Physical problem with the power port or footswitch, or some kind of software bug? Lmk if you've had this same issue or have an idea as to how to solve it. Thx!
