I was wondering what you meant by "Does it always pop, or only when there is audio running through the pedal." It is a very loud audio pop, something you'd initially think is a switch problem. The pop occurs when I hit the middle switch; switching to preset 10:2 it pops once. But as I just noted above, it does not repeat, nor does it happen any other time this switch us used; so it isn't the switch itself, I wouldn't think. Thanks
