I bought a Carbon Copy yesterday, I love the delay from this pedal and I would like to keep it but I am getting an annoying POP sound every time I turn it off , I tried using: battery, ac adaptor, within my chain, by itself, with my bass as well with my accoustic guitar and the only way to get rid off of it is turning the volume in the amp all the way down. The noise is that loud that make this pedal unusable in a live situation. Is this how this pedal suppose to work? neither my VT Bass nor TC Chorus make this noise. Really appreciate your input, so far seems like I will stop at GC tomorrow to return this baby.
