CTRL CHANGE commands for any controller’s preset). Control output signals are lead
to terminal strip that enables to connect up to eight JACK MONO plugs or cable
connected to amp’s FOOTSWITCH INPUT.
Basic characteristics:
- MIDI IN input and MIDI THRU output

controlling of each function
- rotatable switch to set MIDI channel (1 to 16)
- control commands select switches (Program Change and/or Control Change)

(if the output No. 6 is active) + 16 (if the output
No. 7 is active) + 32 (if the output No. 8 is active)
