Also, super cool effect - automate your vocal verb send to go post fader, level up, and then automate the volume on the actual vocal track to go down. It creates a kind of 'falling into a hole' effect that can be really cool when used properly.
I may be misunderstanding, but from my knowledge this effect you speak of would be done by setting the FX send to pre-fade. Having it on post-fade would mean the verb send would diminish along with the fader level being pulled down.
Once again I may be misunderstanding or have my wires crossed, but that statement didn't read right to me.
