The new D’Addario NYXL strings will bend farther, sing louder, and stay in tune better than any string youve played before. A new carbon steel core and nickel-plated steel winding provide not only a great feel and long life, but an up to 131% increase in tuning stability. NYXL Bass strings deliver deep, powerful lows, focused punch, and accentuated harmonics. Designed for all playing styles, NYXL Bass provides more dynamic range and sustain than any other bass string.
