XT Nickel bass strings offer enhanced strength, better pitch stability, and longer-lasting performance than standard bass guitar strings. The XT coating provides advanced corrosion resistance, while still retaining the bright tone and natural feel of an uncoated bass string. Beneath the coating, XT Nickel bass guitar strings are constructed with a NY Steel core, nickel-plated steel wrap wire, and Fusion Twist technology, resulting in added resilience and tonal versatility, excellent for a wide range of musical styles. This 50-105 Medium gauge set has a higher tension, affording increased low-end response and output.
