Connecting the Revival Footswitch to the F/SWITCH input at the rear of the RevivalDRIVE provides two further functions.
With the pedal’s MID ASSIGN switch set to F/SWITCH, this allows you to apply the adjustable mid boost to whichever channel is currently selected.
The second footswitch “overrides” or removes each channel’s BLEND control from the signal path. With the BLEND knob set for a mix of DRY and O.D. signals, engaging the DRY OVERRIDE effectively removes the DRY component and reverts to a 100% O.D. signal.
