I'm going to assume you mean an AD60. No clue what strings are on it now and if you bought it used all bets are off. That said, strings are (relatively) cheap so you can always experiment. In my mind, "twangy" suggests fairly light strings. A heavier gauge might help. If your guitar has lights now, mediums might help. Coated strings, different formulations like nickel bronze/aluminum bronze or monel.
