My HD500 is connected to a PA system (with power amplification) via XLR cables, and the other day, the HD500 failed to put create an output signal. The only difference I saw between the time it was working and now is that both of the EXP LED's are lit next to the pedal instead of just one. Pressing on the pedal to try to alternate EXP modes does nothing. I would greatly appreciate any help!
Thank you,
Jon
