NYXLs will bend farther, sing louder, and stay in tune better than any string you’ve played before. As our premium uncoated string, NYXLs offer higher break strength, enhanced tuning stability, and accentuated mid-range response. Made with a NY Steel core, premium nickel-plated steel wrap wire, and Fusion Twist technology, NYXL pedal steel guitar strings are tough enough and versatile enough to handle anything. This 12-38 Custom Medium E9 set is designed for E9-tuned pedal steel guitar, using the gauge made popular by Paul Franklin.
