The Martin MM12 Retro is a set of light-gauge acoustic guitar strings built around Monel — a solid nickel and copper alloy wrap wire — wound over a tin-plated hex core. The result is a distinctly different character than phosphor bronze or 80/20 strings: the Monel wrap softens pick attack, letting your guitar's own tonewoods come through more naturally. These are a particularly good fit for acoustic players who find bright bronze strings overwhelming their instrument's voice.
Martin's Retro line draws on Monel string-making that goes back to the 1930s, and the MM12 delivers that same character in a modern, reliably manufactured package. The Monel wrap wire is naturally corrosion-resistant — not just nickel-plated — which contributes to a longer usable string life. At .012–.054 light gauge, they balance comfortable playability with enough tension for solid projection. They also work well with soundhole pickups, since the nickel alloy wrap responds more predictably to magnetic pickups than bronze-wound strings.
