Maximum Sound And Durability…

Earthtones strings use select phosphor bronze, then their CYCLECOAT process strengthens the strings at the molecular level which adds tonal crispness and increased durability, while dramatically resisting corrosive elements that reduce life and tone. Giving a smoother feel with stellar bendability

The CYCLECOAT process uses repetitive hot/cold cycles that close up the microcracks that cause tonal loss and premature breakage. It’s the microcracks in normal strings that allow a string to go dead or break quickly. Kerly strings say… “We close up the cracks and our strings counteract sweat, corrosion and quick breakage.”  It’s the repetitive expansion and contraction of the metal, due to both temperatures, that change its structure giving it the added benefits.
