The wrap wire is solid Monel — a proprietary nickel\/copper alloy — not nickel-plated. That distinction matters: because the Monel is solid rather than plated, there's no coating to crack or flake, which means the natural corrosion resistance comes from the material itself, not a surface treatment.\u003c\/p\u003e\n\n\u003cp\u003eThe MM13s are a medium gauge set (.013–.056), suited for acoustic guitarists who want more volume and projection than lighter gauges provide. Martin pairs the Monel wrap with a tin-plated hex core wire, which helps prevent galvanic corrosion where the core and wrap wire meet. The result is a string that holds up well over extended playing time while keeping the tonewoods in the conversation — the solid nickel\/copper alloy blend is specifically designed to reduce pick attack and let the guitar's natural voice come through.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Features:\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e6-string acoustic guitar set, medium gauge: .013 | .017 | .026 | .035 | .045 | .056\u003c\/li\u003e\n  \u003cli\u003eWrap wire: solid Monel (nickel\/copper alloy) — not nickel-plated\u003c\/li\u003e\n  \u003cli\u003eCore wire: tin-plated steel hex core\u003c\/li\u003e\n  \u003cli\u003eNatural corrosion resistance without coatings\u003c\/li\u003e\n  \u003cli\u003eReduced pick attack lets the guitar's tonewoods be heard clearly\u003c\/li\u003e\n  \u003cli\u003eCompatible with 6-string acoustic guitars; also works well plugged in\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e Martin\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e MM13 Retro Acoustic Guitar Strings\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSKU:\u003c\/strong\u003e MM13\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e New\u003c\/p\u003e\n\n\u003cp\u003eSince 1872, C.A.
