Here is the goal, I have a podxt with fbv floorboard and a boss gt-3 effects processor. I want to tie in the gt-3 with the pod, but only when I hit the fxloop button on the fbv. The pod xt will also be put on an acoustic channel to let the gt-3 effects come through

cleanly. How do I achieve this? what do I put where? What cable goes from what output/input, return/send, etc...?
