D'Addario custom light gauge coated phosphor bronze acoustic guitar strings. With the Exps D’Addario has reinvented the way extended play strings are made. An ultra-fine EXP corrosion-resistant coating is applied to the wrap wire BEFORE it’s wound onto the core. The EXP Coating protects strings from corrosion and wear that can sap the life out of your sound. The EXP Coating is so fine, it’s virtually undetectable and allows strings to maintain their natural, round wound feel.

Gauges: 11, 15, 22, 32, 42, 52
