Special EXP coating extends string life dramatically without losing that natural feel!
An ultrafine layer of EXP Coating is bonded to the phosphor bronze wrap wire, then wound onto the hex-shaped core wire. 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. Natural round wound feel and sound fresh and bright and last 3 to 4 times longer than traditional guitar strings.
Genuine phosphor bronze alloy retains flexibility as well as brilliant tone for many hours of hard play. Computer-controlled wrapping around a hex core ensures consistency and extends life. Many top players won't play any other brand.
D'Addario is the world's largest manufacturer of strings for musical instruments. Many top guitarists won't play any other brand. Regardless of your playing style, D'Addario has a set that's right for you.
