Still a bit new to the Tonex pedal, but I notice that a second click of the A, B, or C switch goes to a bypass of the rig.
I know an expression pedal or switch can already be used like a morph, to apply changes to the current rig.
Maybe if a second click could load some alternate rig, that might be a good use. So instead of just 3 on ABC, that would give you 6 - A, A alt, B, B alt, C, C alt.
Also, maybe could there be a Feature Request section for this kind of suggestion?
