Elixir - strings acoust 80/20 Poly Med 13-56

Elixir Strings Acoustic 80/20 Bronze with POLYWEB Coating deliver a warm, 'played-in' tone together with extended tone life that players have come to expect from Elixir Strings. The #1 acoustic guitar string, Elixir Strings provide consistent performance, smooth feel and reduce finger squeak. With less hassle and expense of frequent string changes, you enjoy more time making music.

Elixir Strings is the only brand to coat the entire string, protecting not only the outer string surface, but also the gaps between the windings. Elixir Strings retain their tone longer than any other string, uncoated or coated*. The Anti-Rust Plated Plain Steel Strings also resists tone-deadening corrosion, ensuring longer life for the entire set.
