Martin FX Silk & Phosphor Acoustic Guitar Strings

Start with high quality carbon steel wire – with a round core, please. Wrap it with silk nylon and then finish with a phosphor bronze wrap. That’s the process Martin uses to create these sweet-sounding, easy-to-play acoustic guitar strings. The construction gives them a long life, and they stay in tune longer too. Light feel, long-lasting intonation, and the round core wire and custom gauging also reduce finger fatigue. Yay!
