Your co-pilot for fluid, expressive acoustic playing. A lighter core wire wrapped in Kovar — a nickel-cobalt alloy — boosts flexibility and playability while beaming out crystal-clear clarity and perfectly balanced tone. Lower tension isn't a compromise, it's a deliberate design choice that opens up your technique and lets you steer every nuance into orbit. Natural corrosion resistance keeps them sounding stellar mission after mission. Acoustic strings engineered for players who chase precision and power in equal measure.
