D'Addario EXP11 Coated 12-53 Acoustic Guitar String Set
D'Addario EXP11 Coated 12-53 Acoustic Guitar String Set: Gauges: 12-16-24-32-42-52. EXP Coated Phosphor Bronze Acoustic Guitar Strings provide longer life and increased durability coupled with the brightness, clarity, and sensitivity you've come to expect from D'Addario strings. Here is how it works: An ultrafine 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. And since the EXP coating is crosslinked to the wrap wire prior to winding, the strings sound fresh and bright. New-string tone lasts 3 to 4 times longer than traditional guitar strings.
