D'Addario XS Acoustic Phosphor Bronze Strings, 12-String Light (10-47)

Featuring an innovative ultra-thin coating and premium materials, the XS 12-String strings deliver enhanced tone, tuning stability and dramatically increased lifespan. The XS coating protects against corrosion and buildup while maintaining an uncommonly smooth feel. Beneath the groundbreaking coating are NY Steel hex cores and phosphor bronze wrap wire, chosen for their balanced warmth, enhanced harmonics and superior intonation. Digitally-controlled winding and Fusion Twist technology provide 1:1 consistency and prevent slack in the twist for maximum break resistance. Whether recording in the studio or performing on stage, the XS 12-String strings are designed to keep your 12-string acoustic guitar sounding its best.

Ultra-Thin Coating Preserves Tone and Feel

D'Addario's quest for the perfect coated acoustic string led to the development of an ultra-thin polymer coating that protects strings without sacrificing tone or playability. The XS coating is undetectable to the touch, eliminating the "coated string feel" that plagues other coated options.

Premium NY Steel and Phosphor Bronze Materials

At the core of each XS 12-String string is a NY Steel hex core, chosen for its ability to produce balanced tension and enhanced tuning stability. The hex core gives the phosphor bronze wrap wire more surface area to adhere to, resulting in warm, bright tone with clear, balanced harmonics. Phosphor bronze is a popular acoustic string alloy, prized for its warm and balanced tone that pairs well with 12-string guitars. Together, the NY Steel core and phosphor bronze wrap wire are designed to keep your 12-string acoustic guitar sounding its best.

Superior Build Quality and Consistency

Over 300 years of string-making experience have enabled D'Addario to perfect their craft. The XS 12-String strings feature digitally-controlled winding, ensuring each string within each set meets D'Addario's strict 1:1 consistency standards. D'Addario's proprietary Fusion Twist technology is also employed in the making of each XS 12-String string. Fusion Twist is a heating process that fuses the plain steel wrap wire together at the ball end. This unique process results in a wrap wire with enhanced break resistance and the ability to hold pitch better than traditional plain steel strings.
