Pack of 3 sets of strings. Referred to as'' Custom Light,'' EXP26 strings are a D'Addario original hybrid gauge and a comfortable compromise for players who want the depth and projection of light gauge bottom strings, but slightly less tension on the high strings for easy bending. D’Addario’s EXP coated strings now feature plain steel strings and hexagonal cores made of our revolutionary NY High Carbon Steel. Envisioned, perfected, and manufactured by D’Addario in New York, this newly engineered, break-resistant, high-carbon steel wire delivers unprecedented strength and pitch stability. Combined with the highest quality wrap wire materials, precision drawn and micro-coated on our advanced proprietary machinery, each EXP set maintains that familiar uncoated tone while adding up to 4 times more life. Gauges: Plain Steel .011, .015, Phosphor Bronze Wound .022, .032, .042, .052.
