An ultra-fine layer of EXP Coating is bonded to the phosphor bronze wrap wire which is then wound onto the hex-shaped core wire. The result is a built-in barrier against the corrosion and wear that can quickly sap the life out of your strings and your sound. EXP coated phosphor bronze strings have a natural round wound feel and sound fresh and bright with a "new string tone" that lasts three to four times longer than traditional guitar strings.
From the Manufacturer
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 EXPs are the most natural-sounding, longest-lasting coated strings available. EXP Coated Technology starts with the highest quality wrap wire materials, precision drawn and micro-coated on our advanced proprietary machinery. Strings are then wound normally, delivering tone and feel identical to D'Addario's world renowned acoustic strings, with a minimum of 4 times more life. You won't believe they are coated!
D'Addario, the world's largest manufacturer of musical instrument strings, is known as The Players Choice with a reputation for unsurpassed quality and consistency. D'Addario's innovative packaging reduces waste and provides protection from corrosion. All D'Addario strings are manufactured in the U.S.A. using proprietary, digitally controlled, state-of-the-art machinery for unmatched performance, set after set.
