Just to go kind of old-school, I recorded this little song intro with my iPhone and it's internal microphone in my kitchen, iPhone mic pointed toward sound hole, about 10" away. 4 tracks: an arpeggiated chord, two tracks of simple plucking the bass note, and a little modal melody on the 4th track. Used internal reverb and delay build into Garageband. Again, this is a 5$ application.

Cheap 60$ acoustic guitar BTW, at least that's what I paid for it used on Craigslist. New they were around $300.
