Title is self explanatory. I pulled out the C9 out of the closet this weekend and I was disappointed to find that upon turning on the unit, it stays stuck on one of the nine voices no matter which number I’m on. All other knobs on the unit function properly, so I’m a little stumped at what went wrong here. I purchased the pedal used about 3 years ago and used it with the same power supply it arrived with (granted, I’m not sure if it’s the same one manufactured with the pedal, but it always worked perfectly).

Is there any reason as to why my pedal is working? I pack it in a small duffel bag with other pedals/cables but I don’t throw it around or anything, so I don’t know if it could be an issue where the unit broke from bouncing around in the bag.
