NYXL1254 is a heavy gauge set with a high carbon steel 3rd/G string for more flexibility than traditional 12-gauge electric strings. 

D’Addario NYXL guitar strings will bend farther, sing louder, and stay in tune better than any string you’ve played before. 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 up to 131% greater tuning stability by utilizing a completely reinvented wire drawing process coupled with a revolutionary “fusion twist” process for the plain steels. 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.
