Ok.... I've been trying to record an acoustic guitar track. My friend and I have a Rode Nt-2a, an AKG c 200B, 2 57's, 2 smason c02s, and a Shure KSM 27. I've tried many diff mic placements with many diff mics. The problem is when we go to record we get terrible string buzzing, the acoustic is a Martin DM Mahogany Dreadnought. Any ideas on how to get the strings to stop buzzing? It is mainly the low string that causes the most problems. How do people like Jason Mraz and Dave Matthews get their acoustics so sweet sounding?
