I want to plug an external effect box into the FX loop of the Pod Go. The effect box has a Mono in and then Stereo out. I obviously would use a TRS cable out of the effect and back into the POD. But what about the other cable? Do I use a Mono cable out of the POD and into the Mono in on the effect pedal? Or do I use a TRS stereo cable out and only use 1 of the Y cable connections to the pedal? Thanks Tim
