I just ended acoustic guitar + vocals recording session at my studio. Here's the last setup:
 
1. Sennheiser MD421 near 12th fret, aimed a little bit away from the soundhole.
2. DI: internal mic.
3. Stereo setup: 2 pcs AKG C414B-ULS/omni pattern in wide A/B about one meter away from the guitar.
4. Manley Reference Cartioid as vocal mic.
 
Some EQing in the desk before A/D.
 
I ended up using only Manley and the AKG's in the final mix because guitar bled in Manley so much I did not need another close mic for guitar. AKG's gave nice, natural room ambience for the guitar but also for the vocals.

You lost me after step two lol

But guessing you used a total of 4 external mics plus the internal pickup?

My little M-Audio Fast Track Pro (still works great) has only two inputs, I believe so this might not be possible for me.

I'll bet your recording sounded kick ass though ;)

> But guessing you used a total of 4 external mics plus the internal pickup?
 
Yes!  one dynamic near fretboard, two condensers to pick up the ambience. Internal mic to DI and another condenser for the vocals.
 
This time the equipment was better than the young, inexperienced singer-songwriter but he was very happy with the result and will release the recorded two tracks.  I have lots of cool gear because I own a decent recording studio. :)

Dilly dilly!

And thanks for clarifying that!

I ask because I am wondering if I need more gear lol

Oh, you always need more gear.
 
NT1a is very low noise, meaning you can move it further away for a more natural sound.
I record in a study surrounded by packed bookshelves. Very dead acoustically.

For Jesus sake. Just put a Rode NT1A in front of it and hit Record.

There's some good advice about placement listed above.  If you're just beginning recording acoustic guitar I'd recommend using just one mic and record in mono.  You won't have phase issues that way.  As for mics, the Shure SM81c is a standard.  You can find them used under $300.

HI:)
 
I've had very good results with 2 mics:
 
1. One on the neck directed to the hole of the guitar about 10-20 cm away from the guitar, one right of the bridge directed to the hole, about 10-20 cm away from the guitar.
Panned hardly.
 
2. Both mics left and right the head of the player directed to the guitar, quasi over the shoulders (Listening as the guitar player listens)
Panned hardly.
 
3. Just one mic in front directed to the hole, but at least 1 m away from it (belongs to the room)
 
4. A Combination of  1-3 or all together:)
 
Bassman.

I aim the mic at the neckjoint, a coupla feet away. I so happens that the "mike stand" is attached to a bookshelf (with books in it) so this is my background wall. Just don't use a microphone with obvious quality flaws. I've used a lots of more or less cheap mics with "good" results.: Røde NT2, AKG414, Shure SM57, Shure SM7b, Neumann TLM102. 
Interestingly, I find that the cheap Chinese Superlux S241 works great in this setting, and is now my favourite.
I'll give you a link, because it is unbelievingly cheap for what it delivers:

To me, the sound of an internal/bridge mic is one of the most annoying sounds i know. ("Tick-tick-quack")
I have a few high quality acoustic guitars, and I want to hear the guitar, body and all. Not a "string signal"

2 mics for me (but you need also to consider the room in which you are playing).
 
I use a 414 and a Cascade FatHead Ribbon mic.
 
This is usually my solution and I like it.
 
I am also using a compressor before the AD....
