Just wanted to add my vote for this. This is a great feature that I’ve enjoyed on other effects devices.
It would be great if I could set my H9 to bypass the wah if the expression pedal is at the heel or toe position.
Also, some of the other effects units have a “timeout” option that bypasses the effect after the expression pedal hasn’t changed for a preset amount of time.
Either (or both) of these options would be a great addition!
