An ultra-fine layer of EXP Coating is bonded to the phosphor bronze wrap wire which is then wound onto a NY High Carbon Steel core 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. We know that choosing the perfect string is vital to a musician's sound. EXP coated phosphor bronze strings have a natural feel and sound warm and bright with a "new string tone" that lasts three to four times longer than traditional guitar strings.

D'Addario - Making strings for over 300 years

Behind every set of D'Addario strings are over three centuries of fine craftsmanship. The D'Addario family tradition began in the tiny town of Salle, Italy in 1680 where they made assorted instrument strings for over two hundred years before relocating to New York in 1905. As the modern string making industry began to develop, the D'Addario family emerged as innovators by designing the winding machine most string makers still use today. And while their techniques have modernized, the pride that goes into each set of strings dates back to the D'Addario family's earliest roots.
