I agree in that you will most likely end up using 2 mics, but even with just two there are lots of options.

Are you familiar with different micing techniques, such spaced pair (A-B), X-Y, and Mid-Side? If not you might want to read up a bit and then experiment.

Once you discover a preference for the micing technique you can then experiment to fine tune its use for your application. There are variables such as distance from the guitar, how mics are pointing relative to the guitar, spacing between mics, etc. Then there are the mic variables such as sdc and ldc, as well as polar patterns (cardioid, omni, figure 8, etc).

I've found that X-Y is a pretty safe way to get a reasonable recording, but I don't really care for it that much for solo fingerstyle. I've found I prefer A-B, and depending on the mic and room, I'll place the mics 14-20" apart, back 16-30" from the guitar, and I pan them hard left and hard right.
