Description:
Martin M150 Original Medium Strings bring back the 80/20 bronze sound that helped define classic acoustic tone. Designed for players who want powerful low end with brilliant highs, they deliver strong projection and clarity for strumming or lead work.

With a medium gauge set of .013–.056 and 189.6 lbs total tension, these strings suit larger-bodied guitars and players with a firmer picking hand. They are a solid choice for bluegrass, flatpicking, and any style where volume, sustain, and tuning stability matter.
