With a combination of a thinner core and thicker wrap wire, Martins Authentic Flexible Core guitar strings offer lower tension for easier fretting and bending, while still delivering rich tones. Available in Custom Light (.011 – .047), Light (.012 – .054), Medium (.013 – .056), six-string sets and an Extra Light (.010 – .054) 12-string set, the phosphor bronze strings are made in Martin’s own string manufacturing facility. This video discusses some of the strings’ qualities.
