D'Addario EXP Coated XL Nickel Bass String Set Super Long Scale - 4-String 45-100 Light EXP170SL

D'Addario EXP Coated Nickel Round Wound Electric Bass Strings use an ultra-fine layer of EXP Coating that is bonded to the nickelplated steel outer wrap wire which is then wound onto the hex-shaped core wire. The result  of this EXP Coating by D'Addario is a built-in barrier against the corrosion and wear that can quickly sap the life out of your strings and your sound. D'Addario 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 electric bass strings.
