Martin SP 80/20 Bronze Acoustic Guitar Strings

The creation of these 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 strings are plated with a smooth, acoustic bronze finish. Though this 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. Martin SP strings are available in 80/20 Bronze extra-light, custom light, light, and medium gauges for 6-string acoustic guitars and an extra-light gauge for 12-string acoustic guitars.
