The WET Only Footswitch serves as a remote foot-controller that bypasses the SPLIT & MIX toggle switch on the PLUS Pedal’s side panel, thus letting you switch in and out of the WET Only mode on the fly.
This flexibility allows you to build up a rich layer of ambient sound effects and then quickly unmute your instrument and return to playing on top.

(Note: Switch for OUT 1 must be set to MIX in order to use footswitch.) When using the WET Only footswitch (plugged into “CLEAN OUT/FSW”), you can still access the DRY only signal through a special
DRY OUT output built into the Footswitch itself.
