I still haven't gotten a sound on my acoustic that I am really happy with...granted I'm playing on a low end Martin..not a bad guitar but certainly a few notches down from the better ones.
If you go by what has been written about recording acoustic guitars , then you would use a few SDC mics one around the neck about 12" up and fairly close and one closer to the sound hole on the other side.
Clint I think you have made some pretty good guitar recordings already. No harm in trying to better it though.
My best results with my Martin have been to mix a combination of direct input from the electronics and then use at least two other mics. Not sure why SDC are the type of mic recommended as I think any decent mic should pick up the sound.
So I end up with usually at least three tracks from my acoustic...what I do but there may be better ways.
