Acoustic guitar strings constructed with nickel-plated steel wrap wire. Played for their bright, vibrant presence and dynamic punch. Ultra-thin NANOWEB Coating provides a traditionally textured, “uncoated” feel. Patented coating technology protects against common corrosion, extending tone life longer than any other brand’s coated or uncoated strings (Elixir Strings player survey). Anti-Rust Plating on plain steel strings ensures longer tone life for the entire set. Gauges: .011 .015 .022 .032 .042 .052
