Martin Retro Extra Light Guitar String Set (10-47)
Martin Retro acoustic guitar strings are crafted from a long-lasting proprietary nickel-based alloy blend that mellows quickly to a warm vintage tone that brings out the unique, woody sounds in your guitar.
Retro strings are made with tin-plated steel core wire and solid Monel wrap wire, a proprietary blend of nickel and copper that is naturally corrosion resistant. Martin offers modified gauging on the B, D, and A strings for modern playability. The modified gauging makes the string easier to play with a more balanced feel and clear intonation. MM110
