I have used my M13 at shows now for about 3-4 years (I can't really remember which year I got it!), without issue. Then on Saturday, with the exact same setup as I have used in the previous 200 shows, I was wickedly shocked by my vocal mic!!!
I trouble shot the rig, and it turns out, my M13 is the problem.
I am still using the power supply that came in the box with the pedal.
Please help. I have shows coming up in a couple of days, and can't afford to spend weeks messing around returning purchases, taking the pedal to dealers, etc... Any ideas? Please HELP.
