D'Addario XS Nickel-plated strings bring the company's cutting-edge XS-coated formula to the electric guitar for the first time. These strings yield iconic D'Addario tone, but with a longer lifespan that ages gracefully. The ultra-thin XS coating not only preserves tone and longevity, but it also addresses common guitar player gripes about coated strings with their reduced string noise, lightning-fast playability, and superior resistance to fraying. Most players agree: if you're looking for coated guitar strings that sound great and give you longer hours of playtime, D'Addario XS Nickel-plated Steels are a clear winner.
