The Martin MA550 Authentic Acoustic SP® 92/8 Phosphor Bronze Guitar Strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules.

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.
