Product Review

These strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. We start with our highest Tensile-Strength core wire, then tin-plate it on all six strings for added corrosion resistance; because what you don’t see matters! When coupled with our highest quality wrap wire you get consistent true Tone that you can count on song after song. Available in 80/20 Bronze and 92/8 phosphor bronze. Martin authentic acoustic SP strings offer excellent tuning stability, corrosion resistance and great playability.
