Martin Phosphorus Medium 13-56 Marquis

Martin Authentic Acoustic Marquis® Silked Phosphor Bronze Strings are designed to deliver the warm, rich tone of phosphor bronze while helping protect your acoustic guitar. Each string features a soft silk wrap at the ball end that helps reduce wear on the bridge holes and bridge plate during installation and playing. The added silk wrap also increases the thickness at the ball end, helping bridge pins remain securely seated, particularly on vintage instruments and older guitars with worn bridge pin holes. Combined with Martin’s precision string manufacturing, these strings provide consistent performance, natural response, and the warm, balanced sound that phosphor bronze is known for. Built to Martin’s exacting standards, Authentic Acoustic Marquis® Silked strings offer dependable performance for players who value both exceptional tone and added protection for their instrument.
