D’Addario XT Nickel 9–46 coated strings give you the enduring performance of modern strings with classic bright tone. Each string’s nickel-plated steel wrap is covered by a thin, corrosion-resistant XT coating that protects them from sweat and grime, so they sound and feel new much longer. Under the coating, a NY Steel core and nickel wrap deliver the lively attack and versatile tone you expect – the coating doesn’t dull the sound, it only preserves it. Gauges: E4 .009, B3 .011, G3 .016, D3 .026, A2 .036, E2 .046.
