Martin classical-style guitars, like this one, are sometimes converted to steel strings with a new top, X-bracing, and so on. This guitar has been converted, with the addition of a pin bridge ? a pyramid bridge with the same footprint as the original nylon strings bridge. The stiffness of the top, with the pyramid bridge, takes extra-light gauge steel strings with ease. The result is a steel-string guitar with an abundance of bass, very sweet trebles, and a self-generated reverb that lends depth and richness to the overall tone. This is a wonderful guitar for someone who likes the wider, non-radiused necks that come with the Martin classicals. It?s also a great guitar for lovers of fine Brazilian rosewood ? the back and sides here are top-grade!
