Martin Unpackaged MSP Phosphor Bronze Acoustic Guitar Strings - Medium

New - Martin unpackaged MSP "Studio/Performance" acoustic guitar strings. The Studio/Performance series strings are ideal live, in the studio, or wherever maximum string life is desired. The creation of these new high performance strings is a result of research done in cooperation with specialty steel producers. Due to the development of an industry leading ultra-high quality steel core, Martin SP strings resist breakage better than average strings. In addition, both the core wires and the plain string are plated with a smooth acoustic bronze finish. Though the golden bronze finish does enhance the beauty of your guitar, its purpose is much more functional - to prolong brightness, string life, and superior tonal quality to meet the high expectations of demanding musicians. Gauges 13-17-26-35-45-56. Discount: 12 sets for $42.00, 48 sets for $144.00.
