Ernie Ball 0220 Everlast Coated Phosphor Bronze .020

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 92% copper, 7.7% tin, 0.3% phosphor wire wrapped around a hexagonal brass-plated steel core, the Phosphor Bronze strings offer a warm, bass-rich sound with clear and bright treble.
