ERNIE BALL 2554 EVERLAST 80/20 MEDIUM

Everlast coated acoustic guitar strings use revolutionary nanotechnology that repels unwanted moisture and grease that negatively affect sound. Our proprietary treatment is applied to both the internal hexagonal core and the external winding wire, to ensure ultimate protection without compromising sound or tactile sensations. Made with 80% copper, 20% zinc wire wrapped around a hexagonal brass plated steel core, they create a defined and ringing sound, with pleasant harmonics. Diameters: .013, .017, .026, .034, .046, .056
