Martin MA150 SP 80/20 Bronze Authentic Acoustic Guitar Strings Medium 13-56
MA150 – Gauges:13-17-26-35-45-56
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.
