Have you employed any unorthodox miking techniques on acoustic guitars which have produced a good natural sound, if so what are they?
Probably the most superlative technique for a natural sound would be to set up a stereo pair of mikes at two meters or more, consequently you get the room and the bloom that a real listener would experience during a personal performance. In this situation just moving the pair a fraction may give a perfect sound that needs little work in the mix. Q.
