vocal rever, when to add it?

[coolsoundman]

when you guys add reverb or delay to a vocal track, when do you add it? do you add it in the mix on a bus channel or on the channel track?
is there a reverb added at the mastering stage as well?

As an aux send during the mix.

however you want to/whatever sounds good. I'd suggest very small amounts of reverb or delay just to give it a little depth (unless the room has a bit of ambience to it already).. unless you are consciously going for a REVERB effect. Then, do whatever you want.
