Two button footswitch with TRS jack. This pedal uses momentary switches to select up/down settings on a jamman loop pedal. It is a smaller version of the FS3X schematic with the exclusion of the mode switch.
Here is the switcher (far right) as it was used on a pedal board for a European tour from August 14-25, 2018. Also included on this board is tremolo CWS006, and boost CWS016.
