Overview Specs Plan Info General Information: The dreadnought 6-string guitar was one of the most significant innovation of the Martin Guitar Co. This guitar is the standard and legendary for it's incredible balance, projection and robust tone. Although this guitar model is most closely associated with bluegrass and folk styles, the bold sound and projection is suitable for any genre. While wood selection can be whatever the luthier or customer desires, the classic D18 uses ribbon cut Genuine Mahogany (Honduras Mahogany) back and sides with Sitka Spruce Top. The D28 uses Indian Rosewood with Adirondack Spruce Top. Note that the original pre-WWII D28's used Brazilian Rosewood. Unfortunately that wood is no longer available and is on the endangered species list. Also, since quality Adirondack Spruce can be difficult to obtain, consider either Sitka Spruce, or European Spruce for the top plate and braces. Interested in 3D CNC files for this guitar?
