XT Nickel electric strings feature an advanced corrosion resistance coating, extending string life, while preserving the natural tone and feel of uncoated strings. Nickel-plated steel wrap wire provides a bright, versatile electric guitar tone, great for a variety of musical genres. Fusion Twist technology assures XT Nickel strings stay in tune better, while the NY Steel core wire offers greater break strength—bent two whole steps higher, XT strings are still at less than 75% of their breaking point. XT Nickel strings come with a code, which you can register to earn Players Circle points. XT electric guitar strings are made in the USA—drawn to exacting specifications at our New York production facility.
