D'Addario EXP Coated Classical Guitar Strings offer a fresh, bright tone and a "fret-friendly" round wound feel of traditional non-coated strings, that lasts 3 to 4 times longer. The ultra-fine EXP coating is applied to the silver-plated copper wrap wire, then wound onto a mutli-filament core, creating a corrosion resistant barrier and extending the "new string tone".
All D'Addario strings are precisely wound around a hexagonally shaped high-carbon-steel core wire by computer-controlled machines guaranteeing clear intonation, rock-solid fundamentals, and incomparable consistency in every string. The tight core tension produced through this rigorous quality-controlled process results in a harmonically rich, longer-lasting string.
