92/8 Phosphor Bronze for Rich, Balanced Tone: Designed with higher copper content and a touch of phosphor for a warm, rounded bass tone that stays balanced and present across the frequency range.
Medium Gauge for Punch and Power: Gauged at .045, .065, .085, .105, this set delivers more tension and low-end projection—ideal for players who want added presence and definition in their acoustic bass tone.
SP Core Wire for Strength and Stability: Built on Martin’s highest tensile-strength core for lasting performance and superior tuning stability under real-world playing conditions.
Tin-Plated for Corrosion Resistance: All four strings are tin-plated for added protection against sweat, humidity, and wear—so you get tone that lasts, night after night.
Crafted to Martin’s Exacting Standards: Made in-house with the same precision and quality that go into every Martin guitar, these are bass strings you can count on to hold down the groove.
