If I had 4 mics at my disposal, I would run two facing forward and two facing backward, then make a surround-sound mix. That would mean you couldn't run it all into one JB3, because you'd need to keep front and rear separate. As everyone said, lining them up may be hell, because the word clocks aren't exactly the same. Take a look at Henry Hart's recent DMB releases for an idea of what I'm talking about. If you have a way to obtain a 4-channel R-4 for the show, that would make things MUCH easier.
