D'Addario XS Acoustic Phosphor Bronze strings represent a significant advancement in coated string technology. An ultrathin polymer coating on every wound string and a unique treatment on plain steels provide superior protection. These strings offer the highest level of protection, ensuring the longest life of any D'Addario coated acoustic string. They maintain an uncommonly smooth feel while resisting corrosion and buildup for extended playability. High carbon NY Steel cores deliver maximum tensile strength, preventing breakage under normal playing conditions. Fusion Twist technology enhances playability with a precision-ground wrap wire for a smooth feel and consistent intonation. Designed for acoustic guitars, they produce a warm, balanced tone with clear, ringing highs. The polymer coating preserves the natural phosphor bronze tone, allowing its characteristic richness and sparkle. Players can expect 131% better tuning stability compared to standard acoustic strings. Crafted in the USA to D'Addario's exacting specifications, these strings ensure reliable performance for all musical genres.
