Relative POD noob here.  Short version:  I would like my Floor POD (not a Plus) to sound like a "pure" acoustic amp.  Has anyone created a custom preset like that?  Can anyone recommend a recipe or a procedure?

Long version:  I have been playing an acoustic/electric Taylor CE through a direct box to the PA system at church. I bought the Floor POD when I was considering a switch to a solid-body electric.  I still wanted to play through the PA and didn't want to drag an amp around, so the POD looked like a solution. The switch didn't pan out, so the POD has been gathering dust. 

I recently bought a Taylor T5 which sounds beautiful played as a pure acoustic through the direct box.  I would like to expand the sound by using other pickup settings and adding some electric guitar effects, so the POD is looking like a solution again,  I've had fun playing with the amps and effects, but I an't figure out how to get that beatiful unadulterated acoustic tone through the POD.  Any help would be greatly appreciated.
