Martin MA540T Lifespan 2.0 – Long-Lasting Phosphor Bronze Acoustic Strings

The Martin MA540T Authentic Acoustic Lifespan 2.0 strings are built for guitarists who don't want to choose between tone and longevity. The Lifespan 2.0 anti-corrosion treatment is a patented technology developed exclusively by Martin — applied to both the core and wrap wire to fight corrosion where it actually starts, not just on the surface.

Key Features

• 92/8 phosphor bronze construction for warm, articulate acoustic tone
• Patented Lifespan 2.0 anti-corrosion treatment — only available from Martin
• Core and wrap wire both protected against corrosion
• No compromise to tone or playability compared to uncoated strings
• Precision manufacturing held to Martin's own acoustic guitar standards

Ideal For

These strings are a solid pick for acoustic guitarists who play regularly — whether at rehearsal, on stage, or in the studio — and want strings that hold up between sessions. The 92/8 phosphor bronze alloy works well for both fingerpicking and strumming styles, offering a balanced response across the frequency range. If you've been frustrated by strings that corrode after just a few gigs, the Lifespan 2.0 treatment addresses that directly.
