Re: POD X3 LIVE vs. POD X3 PRO vs. POD X3( little red circle shaped one)
From what you said before I replied, I interpreted that you wanted to do it like this:
...and this won't work because nothing will drive the speakers.
So for your Peavey amp, since it DOES have a built-in power amp, it should work this way:
guitar>pod>Peavey fx return
The preamp out is supposedly the effects return's pair if you use the effects loop the way it usually is:
guitar>front end of amp, and then, preamp out>stompbox/fx>effects return, and then, SOUND. Such a setup allows you to use your amp's natural tone and overdrive without having to face problems like bad-sounding mod or echo effects when running them at the front end of your peavey.
