First show after I took my pedal board to bits and put back. It cuts out my entire signal when engaged in the loop of my BDDI deluxe, when toggled off the other effects in the loop function per normal. I checked it is connected properly. Out of distortion goes to in of GR etc. So there must be some fault. It's pure silence, no crackling or anything unusual aside from dead air when it's on. It has power, LED comes on.
