Exp pedal for controlling wet/dry?

Someone on social networking mentioned they use their expression pedal for controlling the wet/dry of the effects they’re using, I tried getting an answer as to how he set it up but never got an answer.

Anyone here do this?

I would guess that there is a split before the wet effects, and the expression pedal sweeps the path between A and B.

Connect an expression pedal.
Go into the block of whatever effect you want to control wet/dry.
Assign expression pedal to that control (and any other you fancy too).

Alternatively if it’s a set of effects, or effects block that don’t have a dedicated wet/dry control, set up a splitter with all effects on one side, and nothing on the other, then set the expression pedal to blend between the two sides.
