An ultra-fine layer of EXP Coating is bonded to the phosphor bronze outer 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. EXP coated phosphor bronze bass strings have a natural round wound feel and sound fresh with a new string tone that lasts three to four times longer than traditional guitar strings.
