D'Addario XL Pure Nickel Electric guitar strings are inspired by the sounds of the 50s and 60s, delivering the rich, warm timbre from the old Days. XL Pure Nickel is our vintage electric string set. In that early era of electric guitar, pure nickel was the main alloy used in electric guitar strings. Made with a high carbon steel core and pure nickel wrap wire, these electric strings revive the rich, clean tones heard in early blues, rock & roll, and country music.
