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.
