The NYXL1046BT is a balanced tension set designed for greater dynamic control and a more consistent feel across the strings, allowing for evenly balanced bending, plucking, fretting, and picking. D'Addario NYXL guitar strings bend further, sound louder, and stay in tune better than any strings you've played before. Designed, perfected, and manufactured by D'Addario in New York, this newly developed break-resistant core made from high-alloy carbon steel and an alloyed steel blend offers an entirely new level of freedom, confidence, and power. NYXL strings provide increased strength and up to 131% greater tuning stability through a completely redesigned wire drawing process combined with a revolutionary fusion twisting process for the plain steels. The newly formulated nickel-plated string windings have improved magnetic properties, resulting in higher output and enhanced mid-range frequency response, providing more presence and crunch. NYXL uses D'Addario's exclusive, New York-made high-alloy carbon steel alloy for unparalleled strength—play fearlessly. The improved tuning stability compared to traditional nickel-wound strings allows you to get in tune faster and stay in tune better. Wound strings offer enhanced mid-range frequency response in the range of 1 - 3.5 kHz, providing more presence and crunch to cut through the mix. The balanced tension sets NYXL1046BT enable evenly balanced bending, plucking, fretting, picking, and strumming: Plain Steel .010, .0135, .017, Nickel Wound .025, .034, .046. Eco-friendly, corrosion-resistant packaging ensures that the strings stay fresh.
