- extended life-span treatment that preserves the natural tone and feel of newly-made strings
- made with high carbon steel found in NYXL and Nickel Bronze for enhanced break-resistance and tuning stability
- thin, hydrophobic coating protects every string in the set from the corrosive effects of sweat & humidity
XT is an amalgamation of string technologies including a microscopically thin hydrophobic treatment on all strings, high carbon NY steel core, and fusion twist ball end fastening, resulting in a string that lasts 3x longer than a regular set while maintaining the tone and feel of a brand new standard set. This intense combination of high-carbon NY steel core wire and plain strings with the extended lifespan treatment across the full set boasts class-leading break resistance, pitch stability, and long-lasting performance.
