NYXL0946 is a hybrid set, combining the high strings from a super light set (.009) with the low strings from an regular light set (.046). The result is a set with strong fundamental low end, but with super flexibility on the high strings. D Addario NYXL guitar strings will bend further, 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.
