D'Addario Guitar Strings - XL Pure Nickel Electric Guitar Strings - Round Wound - Warm, Bright, Vintage Sound - EPN110 - Regular Light, 10-45

10-13-17-25-35-45. Classic electric guitar string tone dates back to the 1950s, when pure nickel was the primary alloy used. As the need for brighter tone and higher magnetic strings grew in the '60s, nickel-plated steel became the industry standard. D'Addario XL strings feature nickel-plated steel, but these EPN110 XL Pure Nickel guitar strings offer a warmer, vintage tone alternative which many enthusiasts prefer.
