Martin SP 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 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.

Gauges 12-16-25-32-42-54.

• Bronze alloy for brilliance and long life
• Studio-quality performance

We use Martin SP strings on a variety of guitars. Most of our customers prefer the Phospher Bronze, but depending on the guitar the bronze can add a nice high-end sparkle.
