onboard channel switching facility, is disabled when you plug a footswitch into this
jack. The MIDI In port (44) and the Z-9 Port (47) are both disabled when a plug is
connected to this jack.
A footswitch may be equipped with LEDs indicating the given switching
status. Each of the two switches is provided with 15 milliamperes current, which
suffices to power a standard LED. The stereo jack plug's mono contact (tip) controls up

clockwise to blend in the processed signal (parallel/passive, wet balance 1-99%,
depending on knob position). When the knob arrives at the Effect position, only the
wet signal (that is, the processed signal generated by the connected effect device) is
patched to the power amp (serial, 100% wet).
