Martin FX Flexible Core 80/20 Bronze Acoustic Guitar Strings

This new generation of Martin FX Flexible Core 80/20 Bronze Acoustic Guitar Strings is what "The Who" would've been talkin' bout if they'd been around back then.

“I love Martin FX strings - they’re the best strings I’ve ever used. My guitars love them too.” — Tommy Emmanuel

Martin FX Flexible Core 80/20 Bronze Acoustic Guitar Strings offer a bright tone with a thinner more flexible core wire that provides great player control with sharp attack, and improved harmonic sustain. While the tension stays the same, the more flexible string also decreases finger fatigue making it perfect for the seasoned performer or the practicing beginner.

Top artists use this 80/20 Bronze string for live performances and studio recording due to its brilliant tone out of the box, which "breaks-in" to a warmer sound.
