There are L&R ins and L&R outs on a stereo pedal. An insert Y cable has 3 - 1/4'' ends one send one return and one TRS stereo end that I presume gets plugged into either the send or return on the effects loop on the pod go. so am I to believe you need 2 insert Y cables to cover the 6 connections or can it be done with only 1 Y cable ??? I'm confused this is so different then an effects loop on an amp I wish someone could draw me a diagram !?!?
