Well after rooting around here to find an answer I found none. What I'm trying to do is use the POD Go in the fx loop on an amp. I'm NOT using the POD Go guitar input but rather merely hooking up the fx loop with the amp's fx loop as you would treat the POD Go like it was just a pedal. Is it not possible to send a guitar signal out of the amp, into the RETURN jack and SEND the POD Go processed sound back out the SEND jack to the amp? I've tried global settings to instrument and line and nothing changes.
I did find a guy's page who mentions the 2 cable method, just send/return to send/return. Obviously the way the PodGO is set up it's not working.
The chain is set up similar to the attached pic, except that all 4 fx slots are in front of the loop, the amp, cabs and eq are all after and turned off. Effects loop is set as you see it in the pic. If set up like the pic, I get no sound.
The Amp is a Katana, set to SERIES. As it appears the Katana is sending out the preamp signal to the POD Go, the POD Go isn't set up correctly apparently although visually as it's set up it makes sense.
Ideally I'd like to separate the "fx loop" itself so the return goes in front of the 2 pedals and 4 fx slots and the send after them but that's not how it works apparently.
Not interested in 4 cable method btw.
