D'Addario introduces a new string brand: D'Addario XT Strings for electric, acoustic, and classical guitar, electric and acoustic bass, mandolin, and banjo. A treatment that extends the lifespan of each string in the set preserves the natural tone and feel of uncoated strings. These strings last at least four times longer than traditional uncoated strings, without compromising the sound or playability that players know and love. NY Steel and Fusion Twist technologies provide unmatched tuning stability and break resistance. The strings stay 131% better in tune than conventional strings! The newly designed premium inner packaging features a resealable zipper that makes opening and storing unused strings easier. The VCI corrosion protection technology embedded in the packaging material protects the strings before use and ensures they remain as fresh as the day they were made.
