D'Addario XL Pure Nickel Classic electric guitar string tone dates back to the 1950's when pure nickel was the primary alloy used. As the need for brighter tone and higher magnetic strings grew in the 60's, nickelplated steel became the industry standard. D'Addario XL strings feature nickelplated steel, but D'Addario's new XL Pure Nickel strings offer a warmer, vintage tone alternative which many enthusiasts prefer.
