MARTIN SP STUDIO PERFORMANCE
Martin Studio Performance strings are the first choice for sustained playability. The special engineered core wire provides greater durability and a true tone, so you can stay in tune and play longer. The 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.
80/20 BRONZE WRAP WIRE
Popular for stage and studio performance due to its brilliant tone out of the box. The tone will mellow quickly into a warm sound.
BRONZED STEEL HEX CORE WIRE
This premium hex core carbon steel wire has a very high tensile strength. The high tensile strength reduces breakage and holds tuning longer. An engineered bronze finish is applied to protect the core wire and enhance the construction of the string. The brass color also proves to be popular for acoustic guitar strings.
