Martin Strings MA550S 92/8 Phosphor Bronze Medium 13 Silked

Martin Authentic Acoustic Marquis Silked strings feature a soft silk wrap that prevents wear and tear on the bridge holes and bridge plate as you play. The added thickness also ensures that bridge pins will stay locked in place, even in older bridges with worn holes. Our impeccable standards for acoustic guitar tone are embedded in our string design and precision manufacturing process. That's why we make our own.
