The 80/20 Bronze strings offer the brightest tones of all D'Addario acoustic guitar strings and are designed to provide you with unprecedented acoustic response. With the addition of the revolutionary XS coating, the bright and powerful 80/20 strings benefit from maximum durability and a surprisingly smooth feel. Incorporating a NY Steel core, 80/20 bronze winding, and Fusion Twist technology, these coated acoustic guitar strings provide superior break resistance and tuning stability compared to standard 80/20 strings, along with a radically extended lifespan.

A true revolution in coating technology that fully protects the string winding against corrosion, for lasting tone and maximum lifespan.
An ultra-thin film is wrapped and then fused to the winding of each string, protecting them from external elements while providing an exceptional smooth and comfortable feel.
Unwound strings receive a unique polymer treatment for an even higher level of protection.
This new coating results in less frequency loss than any other coated strings on the market, delivering the legendary sound of D'Addario strings.

NY Steel is processed at D'Addario's exclusive facilities in Farmingdale, New York. Using advanced machinery and processes, this premium high-carbon steel offers unmatched tuning stability and superior break resistance.

XS strings benefit from superior break resistance and unmatched tuning stability, enhanced by patented Fusion Twist technology and reduced friction at the nut and bridge. Tune less often, play longer.
