For hyper real group vocals, try the C4
I've had these mics for a while, used exclusively with the stereo bar in ORTF formation for drum overheads. They work great for that. Then this past weekend I had a bunch of group female vocals to sing and decided to employ them for that through my Apollo- wow our minds were truly blown by the insane realness of the stereo image to the point where people were confused on playback thinking people were still singing in the room. Madness! The way they slide into a mix with the lead vocal is also just so natural but with great separation, they sit right where you'd like them. Try these for group vocals (if you can manage to snag a pair). You'll be amazed.
