ibanezcollector is correct, however, the pod will revert back to studio direct mode rather than "live w/horn or livew/o horn. In bi-amp mode, the model output send the "highs" signal and the DI output sends the "lows" signal. If you still want to send a signal to FOH, you would have to do it pre-pod. Not too big of a deal, although you could not mute to tune and obviously you could not send a modeled signal to the FOH if you wanted to. I agree that the poweramp set up is the way to go. I like the bean version along with the FBV shortboard. The shortboard is much more visible than the XT Live board and easier to hit the buttons. If I had it to do all over again, I would have got the guitar version and added the bass expansion pack. The guitar version has more support and firmware upgrades. IMHO and YMMV.
