Great pedal and could be used for any always on application. because the problem is only when switching the pedal on. Sometimes it is muffled with 90% volume loss and popping noises. You have to turn it on and wiggle your foot a little to turn it on right then it stays fine until you have to turn it off then on again. It should be an easy fix for someone who knows what they are doing. Problem seems to be with the on and off bypass switch. I received the pedal in this condition and did not cause it. $75 shipped U.S. only. Paypal only.
