Martin FX MFX740 Phosphor Bronze 12-54 LIGHT
Martin FX Flexible Core acoustic guitar strings have a thinner core wire with zinc flashing. This delivers greater player control with sharp attack, increased flexibility and improved harmonic sustain.
Martin 92/8 Phosphor Bronze is an alloy comprised of 92% copper and 8% tin with traces of lead, iron, zinc and phosphor. These strings produce a bright but slightly warmer sound than the 80/20 bronze. The phosphor in the alloy helps them retain their new sound for greater consistency.
