Extra Light Gauge .010 - .047
These strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. These strings start with highest tensile-strength core wire, then tin-plate it on all six strings for added corrosion resistance. When coupled with the highest quality wrap wire you get consistent true tone that you can count on song after song. Martin Authentic Acoustic SP strings offer excellent tuning stability, corrosion resistance and great playability.
