This is a 2022 Martin D-41, one of the higher-appointed guitars in Martin's dreadnought lineup, sitting just under the D-45 in terms of trim and materials. It's built with East Indian rosewood back and sides paired with a solid spruce top, so you're getting the volume and low-end punch dreadnoughts are known for along with the added sustain and complexity rosewood brings to the mix. The abalone trim around the top, rosette, and fingerboard sets it apart visually from Martin's plainer dreadnoughts without going as far as the D-45's full coverage.
