I got a question; I'm sing my 2 EVH 5150 50watt amps for a stereo sound and they are midi switched so I can change the channels on the amps with my POD X3 Live. But I don't want to use the amps modeling from the POD X3 Live, only the effects. I've read about the 4 cable set up, but how does that work on 2 amps? Since the POD X3 Live only has 1 send output... Please advise me.
