Martin & Co Strings – Phosphor Bronze Acoustic Bass Guitar Strings (45/100)

Martin SP (Studio/Performance) Series 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 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.
