D'Addario's XS Nickel coated electric guitar strings extend string life beyond any other set in the company's range while maintaining tonal clarity and playability. The proprietary XS coating delivers maximum longevity and a fast, smooth feel across the fretboard without sacrificing the harmonic richness and definition expected from premium nickel–plated steel strings. This Medium Top/Extra Heavy Bottom set gauges 11–56, engineered specifically to maintain comfortable playing tension when tuning down a full step to D tuning.
Each string features a NY Steel core combined with reformulated nickel–plated steel wrap wire and Fusion Twist technology, providing enhanced tuning stability and superior tensile strength under aggressive playing styles. The round wound construction produces richer harmonics and greater clarity through every sweep, slide, and bend compared to standard coated alternatives. The heavier bottom strings in this set handle downtuned applications while the medium top strings retain enough tension for precise fretting and controlled vibrato across all six strings.
