Ryan,

I've seen lots of shows done this way, Doyle Lawson and Quicksilver kinda helped revive it I think back in the late 70's-early 80's. George knows his stuff on setups, here's some more to consider:

Are you using your own speakers, or house? Are you getting leakage from the back-sides, or are they pretty directional? Plenty far behind them?

I have not used a C1, but have heard it several times in mic shootouts-comparisons -- it seems to me to be a pretty "hyped" mic, lots of low-end and pretty bright treble, very dynamic. I agree it does sound good on recordings, but I might question it for live. Most bands I've seen using the single mic use something "flatter", usually an Audio Technica (4050, 4033a, etc.) -- tried anything like that, or maybe Shure KSM27-32-44?

One band I like that gets fantastic sound with this style is The Wilders, they're a hoot -- www.wilderscountry.com They've used AT and Groove Tubes mics most times I've seen them. They get pretty balanced sound for dobro, banjo, fiddle, archtop and dreadnaught guitar, and bbutt.

Last year at Winfield I saw a setup I hadn't seen before, John Reischman's band was using 2 small-diaphragm condensers set up on a single stand. Here's a quote from Acoustic Guitar October issue from an interview with Jim Nunally, the band's guitar player-soundman:

'Onstage, John Reischman and the Jaybirds use only two AKG 451 condenser mics. "It takes about 15 minutes to do a sound check and it sounds great," Nunally says. "I found angle adapters for the mics that help me get a wider pickup pattern."'

He's not kiddin', it did sound great, but it only took about 30 seconds speakers only, left to left. Some of the best sound at the festival IMO.

Lots of options out there...
