Were you pointing the mike at the sound hole? That's the worst place to aim it. Try using 2 mikes -- one pointing at the bridge and one pointing at about the 12th fret. Have them 1-2 feet away from the guitar at most. Closer if you can manage without bumping them. Adjust from there until you get a good sound.

If you can eliminate room reflections, you will get a better sound.

Good luck and have fun with it.
