The 80/20 Bronze are acoustic guitar strings from D'Addario known for their brightness. They include the revolutionary XS coating, which contributes to maximum longevity and offers a smooth feel. Made with a NY Steel core and 80/20 Bronze wrap wire, these strings feature Fusion Twist technology, ensuring increased break resistance and tuning stability. The 11-52 Custom Light set offers slightly more volume and projection compared to the Extra Light, while maintaining playability.
