Martin Retro strings are a 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.
