Has anyone encountered this? My Mark V 35 foot pedal channel switcher stopped working at practice last Friday. I hit the button, and both the green and red colors lit up, and it sounded like a muted version of both channels was trying to come through the cab. I unplugged the foot switch, and the face plate toggle didn't work either. It's like its perm stuck in channel 2. It's just under a year old so it SHOULD still be under warranty, but I really don't feel like sending it in for repairs. I haven't messed with it in a few days, so I'm hoping it goes away.
