Review D'Addario EXP Coated Phosphor Bronze Acoustic Guitar Strings

An ultra-fine layer of D'Addario's exclusive EXP Coating is bonded to the Phosphor Bronze wrap wire, which is then wound onto the hex-shaped core wire, resulting in a built-in barrier against corrosion and wear. EXP's sound bright and clear with "new string tone" that lasts 3-4 times longer than traditional strings.
