80/20 Bronze are D'Addario's most distinctive acoustic guitar strings, crafted to add a unique luster to your tone. Thanks to the addition of the revolutionary XS cover, they gain maximum durability and an unusually smooth feel. Constructed with a NY steel core, 80/20 bronze wire wrap, and Fusion Twist technology, these covered acoustic guitar strings have increased breaking strength and tuning stability over standard 80/20 strings, plus significantly extended lifespan. This 12-56 Light Top/Medium Bottom set has powerful low frequencies while maintaining flexibility for soloing.

XS breathes new life into coated strings. With an ultra-thin coating on each wound string and a unique polymer treatment on the smooth steel, the XS offers the highest level of protection for maximum durability with an extraordinarily smooth feel. The XS is the most innovative string ever created.
