Martin MM1012 Retro 12-String, Extra Light, Monel Acoustic Guitar Strings

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. Extra Light 12-String E: .010/.010 B: .013/.013 G: .023/.010 D: .029/.012 A: .038/.018 E: .047/.027 Tension: 255.5
