Perhaps the most revered vintage D-28s are the ones created in 1937 with forward-shifted hand-scalloped X-bracing , an Adirondack spruce top , and a 13 / 4 ” neck width . This model is an updated version made with Guatemalan rosewood back and sides , and it includes some subtle spec refinements to make it even more faithful to the original . One of the major updates is a more accurate body profile based on dreadnoughts from the 1930s and 40s . Martin ’ s VINTAGE TONE SYSTEM ® ( VTS ) is employed to age the top and braces , which captures the tone from the 1930s era .
