I've had the same problem, my stomp has been working since I got it, and a few days ago it lost sound while connected to my computer. When it is off signal can get through but as soon as it comes on all sound stops. I've tried switching on and off, factory resetting, updating to the latest firmware and changing the input to USB then back to guitar, but nothing is working. Any Ideas on what I can do? I'm considering taking it to the local music store to see if they can do anything.
