Excellent Tuning Stability | Corrosion Resistant, Tin-Plated Core | Professional Playability
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 92/8 Phosphor Bronze wire which consistently delivers a warm, full and balanced tone.
