The D-15M is an all-solid mahogany dreadnought built in Nazareth: mahogany top, back and sides in satin Dark Mahogany, non-scalloped X bracing and a simple dovetail neck joint. The neck is a Modified Low Oval with the Standard Taper and a 1 11/16" nut, on an East Indian rosewood board with abalone diamonds and squares short inlays, with a bone nut and compensated bone saddle.
Martin describes a full, even sound. For a mahogany top with Golden Era scalloped braces in the Forward-Shifted X Brace pattern, an ebony board and a 1 3/4" nut, look at the D-17. The D-15M StreetMaster is this guitar with a worn satin finish and a Mahogany Burst top.
