Tried the "Feed Thru" jack on the back of the GCX no dice, thought this would be a no brainer but can't seem to get it to work. I suppose I could use a loop for it, but I'd rather not. What the problem?

That's how I ran it, Andrew.

Are you using the guitar's effects loop with the GCX? If so, the effects loop switch on the guitar has to be engaged for it to send the signal to the GCX and thus to the tuner.

Hey, so found out something kind of interesting about the GCX after lots of trouble shooting. The Feed Thru and Guitar Out on the back only work if you are utilizing the Guitar In on the fron of the unit. All this time I've been using the "In" on loop one for my Send from the guitar loop and the "Return" on the last loop to go back to the guitar. The way I've been running it renders the Feed Thru useless.

One more thing, if I'm thinking about this correctly just turning down the volume pot on the guitar allows for silent tuning when everything is hooked up properly, correct?
