Martin Authentic Acoustic Studio Performance (SP) strings are engineered with the performer in mind, and they will always stand up to rigorous practice and performance schedules. The core is Martin's highest tensile-strength which is then tin-plated for corrosion resistance (including the non-wounds). The cores are then wrapped with Martin's highest quality 80/20 Bronze wire which consistently delivers a bright, sparkly tone.
