Martin MSP3150 SP Bronze Light/Medium Acoustic Guitar Strings

Like all the Martin SP Studio/Performance Series strings, the MSP3150 SP 80/20 Bronze Light/Medium acoustic guitar strings are ideal live, in the studio, or wherever maximum string life is desired. The creation of these high-performance strings is a result of research done in cooperation with specialty steel producers. Due to the development of a top-notch ultra-high quality steel core, Martin SP strings resist breakage better than average strings. In addition, both the core wires and the plain strings are plated with a smooth, acoustic bronze finish. Though this golden bronze finish will enhance the beauty of your guitar, its purpose is much more functional-to prolong brightness, guitar string life, and provide superior tonal quality to meet the high expectations of demanding musicians.
