Charted as the pinnacle of Martin's phosphor bronze fleet. Era™ strings dock the best tech in the Martin lineup: patented Lifespan® treatment to fend off corrosion, Flexible Core construction for effortless fretability, and silk-wrapped ball ends — a premium nod to Martin's handcrafted heritage and a friendly fit for vintage instruments. The Artist Light variant, developed with six-time GRAMMY® winner Jason Isbell, swaps in a traditional SP® core to lock in his signature acoustic voice. A new orbit for what phosphor bronze can be. Gauge: Medium .013-.017-.026-.035-.045-.056 Tension: 190.40 Model: MP550T
