D'Addario EXPPR165 Reds Long Scale Light Top/Medium Bottom Electric Bass strings

D'Addario EXPPR165 Reds Long Scale Light Top/Medium Bottom Electric Bass strings have an ultra-fine layer of EXP Coating that is bonded to the copper-plated steel 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 and your sound. EXP coated nickel wound bass strings have a natural round wound feel and sound fresh and bright with a "new string tone" that lasts three to four times longer than traditional bass strings.
