Mic placement and the acoustics of the room you are in will also influence the sound you get, so a mic stand is a good idea. That way you can reproducibly experiment with mic placement.

Fore example, does it sound better pointed at the 12th fret at an angle or with the capsule facing the fret board ? Does it sound better pointed at the sound hole and if so what angle ?

So don't take my word for it, experiment and find out what sounds best to your ear.
