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. Premium by design, these acoustic strings constructed with 80/20 (80% copper, 20% zinc) bronze wrap wire boast a crisp, bright tone with an expressive, vibrant presence. For more of a balance between bold and bright, Elixir's Phosphor Bronze Acoustic Guitar Strings with NANOWEB Coating deliver full-bodied tone and sparkling high-end clarity alongside the same traditional feel as these 80/20 bronze strings.
