DAddario EXP44 Coated Extra Hard Tension
EXP44, extra hard tension, is optimal for maximum string resistance and projection without compromising tone.
D'Addario EXPs are the most natural-sounding, longest-lasting coated strings available. EXP Coated Technology starts with the highest quality wrap wire materials, precision drawn and micro coated on our advanced proprietary machinery. The ultra-fine layer of EXP Coating is bonded to the silver-plated copper wrap wire which is then wound onto a multi-filament core. 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 silver-plated copper classical 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 guitar strings.
