Description
The EXP13 set from D’Addario takes the classic 80/20 bronze acoustic string and wraps it in an ultra-thin protective coating, guarding against the sweat, oil, and grime that normally dull tone and shorten string life. Underneath that coating is a hex-shaped core made from D’Addario’s exclusive NY Steel — the same high-carbon alloy used in the NYXL line — giving these strings exceptional strength and reliable pitch stability, even under heavy playing.
EXP13 is D’Addario’s Custom Light gauge, a hybrid set built for players who want the punch and low-end depth of a light-gauge wound string but prefer a slightly easier feel on the plain strings for bending and fretting comfort. The coating doesn’t mute the sound or add an artificial feel — it simply extends playing life to roughly three to four times that of a standard uncoated set, while keeping the bright, articulate voice bronze players expect.
- Custom hybrid gauging: lighter plain strings paired with light-gauge wound strings for balanced tone and comfort
- EXP coating bonded to 80/20 bronze wrap wire for extended life without sacrificing tone
- NY Steel hex core for added strength and consistent tuning stability
- Corrosion-resistant, eco-conscious packaging keeps strings fresh until installed
- Gauges: Plain Steel .011, .015; Bronze Wound .022, .032, .042, .052
Made in the U.S.A. on D’Addario’s precision-controlled machinery, this set delivers the consistency the brand is known for, set after set.
