D'Addario NYXL guitar strings will bend farther, sing louder, and stay in tune better than other strings. Envisioned, perfected, and manufactured by D'Addario in New York, this newly engineered, break-resistant high-carbon steel core and plain steel alloy delivers a whole new level of freedom, confidence, and power. NYXL's provide more strength and 131% more tuning stability by utilizing a completely reinvented wire drawing process and revolutionary corrosion-resistant tin coating application. The reformulated nickel-plated string windings have greater magnetic properties resulting in higher output and enhanced mid-range frequency response for more presence and crunch. The NYXL0942 set is designed for maximum flexibility.
