Kerly Music strings are seasoned through a patented metal tempering process that exposes them to minus 320F and plus 350F for 24 hours. The treatment strengthens the string at the molecular level, ads tonal crispness, increases durability and dramatically resists corrosive elements that reduce the life and tone of your strings. Tuning is less frequent, and a smoother surface feel is created with stellar bendability.



The CYCLECOAT™ process uses repetitive Hot/Cold, Hot/Cold, 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 closes up the cracks and their strings counteract sweat, corrosion and quick breakage.
