The Martin MA150 is a go-to medium-gauge acoustic string set for players who want a full, balanced feel from a trusted name in acoustic instruments. Built around Martin's Authentic Acoustic SP (Superior Performance) platform, these are uncoated 80/20 bronze strings designed for standard six-string acoustic guitar.
The set uses a tin-plated steel core across all six strings, which helps with corrosion resistance and tuning stability. The 80/20 bronze round-wound wrap wire delivers a bright character that settles into a warmer feel as you play in. Gauges run .013, .017, .026, .035, .045, and .056 — a classic medium set that works well for strumming, flatpicking, and players who want a little more tension and projection from their acoustic.
