These strings employ D’Addario’s proprietary high-carbon steel core and fusion twist technology, ensuring that they bend farther and stay in tune better — even under the duress of a live performance. XT strings boast nickel-plated windings with enhanced magnetic properties for increased output and juiced midrange. You’ll appreciate the presence and crunch that you get out of D’Addario’s XT electric guitar strings.
