D'Addario XTE0946 XT Electric Nickel Plated Steel Electric Guitar Strings, Super Light Top/Regular Bottom, 09-46

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.
