Okay, I just had an idea that might or might not even be possible. Basically, have a true bypass loop box, with a regular switch and a momentary switch. The regular switch would work as normal, accessing or bypassing the pedal(s) in the loop. However, the momentary switch would be able to create a stutter effect, turning off the effect when the regular switch is engaged, and turning on the effect when the regular switch is disengaged. Does/can this exist?
