I'm having a problem with my M9. One of the pedals (middle one on the bottom row) keeps going on and off by itself. Sometimes I will press it on and seconds later it will shut off. Or I will be playing with nothing on and then it will switch on by itself. Seems like it could be some internal glitch or a like something is sticking. The pedal seems to function just like the others (no sticking. Seems to sound and press like normal). Any help would be greatly appreciated.
