Slight chorus/delay vocal effect in Garageband?

I'm looking to put an effect on my vocal track in Garageband that will give it that effect you often here where it almost sounds like two people singing, but just "barely"....I don't how else to explain it except that I haven't been able to find it yet, and the best way to get what I'm after is to record myself singing over the top of my first track.....So you're hearing two vocal tracks, just "offset" by a very small time......Any ideas? Thanks.

You need to select Ambient Vocals....? Is this what you looking for?

Yeah, that's the closest one I found as well...Is there a away to fine tune/tweak that effect to change the delay or anything? That's a little too "spacey"...Thanks.

Down on the right hand side of the screen you can click on a drop down that will display the menu to tweak it to the desired effect.

Sorry thats not so clear, I'm not in front of a Mac at the moment.

If you have any trouble finding it I can check when I go home?
