D'Addario EXP12 Coated Strings Acoustic 80/2

80/20 Bronze are D'addario's brightest acoustic guitar strings, made to give your tone an unparalleled shine. With the addition of the revolutionary XS coating, the bold, bright 80/20 strings obtain maximum life, with an uncommonly smooth feel. Made with a NY Steel core, 80/20 Bronze wrap wire, and Fusion Twist technology, these coated acoustic guitar strings have enhanced break strength and tuning stability over standard 80/20s, in addition to a dramatically increased lifespan. This 13-56 Medium gauge set provides maximum volume and projection, with more tension and resistance.
