D'Addario says this is the 'most technologically advanced string ever created' - a bold statement...  but, when you play these you'll understand what they're talking about!

XT is an amalgamation of string technologies including a microscopically thin hydrophobic treatment on all strings, high carbon NY steel core, and fusion twist loop end, 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 with the extended lifespan treatment across the full set boasts class-leading break resistance, pitch stability, and long-lasting performance.

XT strings are designed both for professional players who need to be ready to play at any minute, demanding instant performance; and also for players who just want to play and don't want the fuss of changing strings.

Features:

• 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
