Martin M1600 Marquis, 80/20 Bronze, 12 String Acoustic Guitar Strings, X-Light 10-47.

Martin created their Marquis line to pamper your guitar by adding a soft thread wrap at the ball ends which prevent wear and tear on the bridge and end plate as you play. This thread wrap puts a comforting layer of protection in place every time you change your strings.
