Of late, when I’m recording an acoustic guitar for a song in which it will be either the only instrument or the dominant one, I’ve had a lot of success using a spaced-pair stereo-miking scheme, with one mic pointing at the guitar body between the sound hole and the bridge, and the other pointing at the neck around the 7th fret. I align both mics on the vertical plane and angle them outward by about 20-degrees. Those are rough placements, and I move the mics around a little to find their sweet spots before settling on final positioning. I’ve used this setup mainly for fingerpicked parts rather than strummed ones. For mics, I’m using a pair of Røde NT-4 cardioid pencil condensers through an FMR Audio Really Nice Preamp (which is a great 2-channel preamp for the money). I record them to two separate mono tracks (which I pan L&R) so that I can play around with the individual levels in the mix. I really like the nice wide sound that you get with the spaced-pair placement. I tried using an X-Y configuration, but I found the image was too narrow, especially for a solo fingerpicked part. For those out there who are stereo-miking acoustics, I’m curious to know what configurations are working out best for you?
