These Martin Authentic Acoustic Lifespan 2.0 Phosphor Bronze Guitar Strings feature a special anti-corrosion treatment to ensure longer life, while retaining their heritage quality tone.

Their patented Lifespan 2.0 treatment from Martin makes these strings last even longer than ordinary phosphor bronze strings. Unlike other coated strings (which often peel off like a bad sunburn), their unique treatment process protects both the core and wrap wire, without compromising the strings tone or feel. Their world renowned impeccable standards for acoustic guitar tone are embedded in this string design and their precision manufacturing process delivers consistent performance. Additionally, these strings come packaged to resist humidity changes, keeping your strings factory fresh. Available in multiple gauges. Boasting a fuller and more balanced tone, the Martin Lifespan 2.0 Phosphor Bronze strings are a great way to get more life out of your next Authentic Acoustic set.
