Does a dual Mic Clip exsist for looping vocals live

[Scott Winzinger <zing@sigecom.net>]

I was wondering if anybody has seen a mic clip that screws into the boom

and branches off to two mic clips that are about a foot apart (to avoid
bleed through).

I am trying to add this to my acoustic show so I can loop my guitar and
then later loop vocal. Is there another way to accomplish this? Won't I
need to have two seperate vocal mics to do this?
