Martin 12-54 Lifespan Phoshor Light (ne MSP7100)

The Martin 12-54 Lifespan Phosphor Bronze Light strings (formerly known as MSP7100) are designed for acoustic guitar players who prefer a light gauge set with a warm and balanced tone. These strings feature a special coating that helps to protect them from dirt, sweat, and other contaminants, while also extending their lifespan.

The string gauges in this set are .012, .016, .025, .032, .042, and .054. They are made from a blend of copper and phosphor, which is a popular choice for acoustic guitar strings due to its warm and balanced tone.

The Lifespan coating on these strings helps to prevent the buildup of dirt and sweat, which can cause the strings to lose their brightness and tone over time. This coating also helps to prevent corrosion, which can shorten the lifespan of the strings.
