Something I through together in about a minute. I was going through a last search of FL Studio to see if there was any hope for a great sounding acoustic guitar for a song I'm working on. This is what I got, though unfortunately it was from a user preset and I can't edit the notes or anything. Sooo yeah. Just used some different rhythms from some of the notes and added drums. Hope it's short enough for you. Might do something with an actual acoustic once I get mics to record.
SORRY THAT NEWGROUNDS THINKS IT'S COOL TO ADD 3 MORE SECONDS TO THE SONG, so this won't work as well as I intended it to for a loop.
