Elixir 80/20 Light Prolong your tone with the same acoustic guitar strings that experienced players worldwide trust to keep their incredible tone longer than any other string available. Unlike other string brands Elixir Strings coats the whole string. This protects not only the outer string surface but also the gaps between the windings where common tone-deadening gunk typically builds up in other brands’ coated and uncoated guitar strings. Anti-Rust Plating on plain steel strings ensures longer tone life for the entire set.
