D'Addario XS Acoustic Phosphor Bronze Strings Light Top/Medium Bottom (12-56)

XS Acoustic phosphor bronze strings feature a breakthrough in coated string technology. With an ultrathin polymer coating on every wound string and unique treatment on the plain steels, XS strings offer the highest level of protection and longest life of any of D'Addario's coated acoustic string, while maintaining an uncommonly smooth feel.

Ultrathin Polymer Coating Provides Maximum Protection

The ultrathin polymer coating on XS acoustic strings shields the phosphor bronze winding from corrosion and buildup, allowing the strings to sing for an astounding 200 hours of playing time. This thin coating does not dampen the tone or feel, providing the warmth and clarity of uncoated bronze strings.

High Carbon NY Steel Cores Create Unmatched Strength

At the heart of XS Strings are high carbon NY Steel cores and plain string wire. This specialized steel provides maximum tensile strength for strings that simply do not break under normal playing conditions. The plain strings are also treated with a polymer to prevent slippage and maximize tuning stability.

Fusion Twist Technology Enhances Playability

XS Strings feature an exclusive Fusion Twist wrap wire that is precision ground to an exacting gage for an uncommonly smooth feel. The Fusion Twist wrap also grips each string wind tightly, preventing stray strands and ensuring consistent tone and intonation up and down the neck.

Warm, Balanced Tone

Designed specifically for acoustic guitars, XS Phosphor Bronze Strings produce a warm, balanced tone with clear, ringing highs. The polymer coating does not dampen the natural tone of phosphor bronze, allowing the characteristic richness and sparkle to shine through.
