Martin Retro Acoustic Strings Medium 13-56

Martin & Co.

Martin's proprietary Nickel/Copper alloy blend wrap wire provides for a reduced pick attack and allows the guitar's tone woods to be heard, not overshadowed. It offers a uniquely mellow, yet crisp, sound. Martin's wrap is a solid Nickel/Copper blend, not nickel plated, meaning there is no chance for defects to allow for corrosion. Martin's proprietary wrap is naturally strong and corrosion resistant, so much so that it has been used in the propeller of Dreadnaught battleships and various machinery and tooling applications.
