Martin 13-56 Retro Monel Light

The Martin MTR13 is a set of retro monel light strings designed for acoustic guitar. The gauges are 13-17-26-35-45-56. These strings are made with a unique monel alloy that provides a warm and vintage tone, as well as improved tuning stability and durability. They are also designed with a special "silk wrap" at the ball end to reduce wear and tear on the bridge and bridge plate.
