footswitch:
Hold the last footswitch (9/Master Boost) for 2 seconds to enter MIDI channel select mode. The LEDs on the 1-8
footswitches will blink. You can then choose MIDI channel 1-8 by pressing one of those. You can also press 9/
Master Boost again to cancel the operation.
Note: The amp will always respond to the footswitch, but the MIDI channel allows it to
selectively respond to standard MIDI messages from other devices.
