Martin MM13 Retro Acoustic Guitar Strings, Medium, 13-56

Martin Retro® strings are the real deal. You get one tough set that offers true, consistent tone and sounds like nothing else on the market. Martin’s solid nickel/copper alloy blend provides a reduced pick attack that allows the guitar’s tonewoods to be heard, not overshadowed. Martin’s proprietary Monel wrap wire is naturally corrosion resistant, so you can play them for a long time with nothing to get in the way of your music.

Retro® strings offer enhanced longevity with warm natural tone, and they sound great plugged in.
