Heya folks

I've bought a Pod X3 Live and i want to connect it into my Peavey 112 Bandit combo amp.

How do I do that? I've tryed the left/right FX return into the high gain (guitar in) but that didn't work so i connected

guitar--> pod--> amp (via effect loop send) and then return into the left FX, but the amp doesn't get the right sound nor does the effects work either.

What have i done wrong?
