D’Addario has released XS, which it has claimed as a technological breakthrough in coated strings. These strings offer players maximum life and a high level of strength and stability — all without sacrificing tone. Setting XS apart from other strings is the new, thin film coating (1/10 the thickness of a human hair) that completely protects the wound strings from corrosion, without dampening the tone. This new film covering is combined with D’Addario’s proprietary dispersion coating, used in the XT line, to protect the plain steel strings as well. With the addition of XS, D’Addario now has the complete and definitive extended life string offering: The X-Series. Players can choose between XT, for enhanced life and a natural feel, or XS, for maximum life and a smoother feel. XS will be available in Phosphor Bronze string sets for acoustic guitar, 12-string guitar and mandolin in the most popular gauges.
