micing acoustic guitar for live purposes

Secondly is positioning of the mic, which should be roughly just over a foot away from the instrument, you will have to experiment on where the mic is pointing to get the best sound, most of the time ive found that if you point the mic directly into the sound hole , you get a very boomy sounding acoustic guitar which you have to spend forever trying to EQ and will very often feedback, so try off setting the mic slightly. You may also want to try adding a second mic and having a stereo pair on the guitar, this is quite a common thing to do. Again experiment with the positioning of the mics to get the best pick up. Also a touch of reverb doesnt go a miss either.

One thing, as mentioned by klemay, is the positioning of the mic. I've always found the best position, both for tone and for GBF, is over the fingerboard, about halfway between the sound hole and the end of the body. Pointing directly at the sound hole can give a very boomy, very prone to feedback sound. For recording purposes I always mike an acoustic guitar in stereo but I'm less convinced about the for sound reinforcement, given that each time you double the number of mics you reduce your gbf by 3dB. Reverb is also likely to cause more, not less, feedback.
Using a guitar pickup (as opposed to a mic) is always an option when high levels are needed, but obviously it DOES alter the overall sound.
Otherwise, speaker (both FOH and monitor) positions need to be considered...as does the overall SPL you're working at. There comes a time when, just like Scotty, "ye cannae change the laws of physics, Cap'n".

Bobbsy hit it on the head with mic placement... Don't point it directly the hole, but put it off-axis while pointing it towards it - the air that comes out of the sound hole, while it's not alot, is enough to give you booooomie-ness on a sesitve condensor. As always with these things, try a few different positions and see what works out best for you.
If you are really struggling with feedback, you should be able to use a 57/beta 57 without too much problem, and still get an acceptable sound.
The other thing to bear in mind is stage level... if you have a loud band, your going still going to struggle to make the acoustic cut through the stage noise, even if the mic is fairly near the guitar!
My 2p. Hope it helps!

I realise that this probably won't help with your level or feedback issues, but it does sound good.
Have a look at this guide for lots of useful info.
