Acoustic Hollow Body Dreadnought guitar
Sitka spruce top, Indian rosewood back and sides
In 1946 Martin started using new materials for his guitars. The most notable change was the use of different type of wood for the top. Before 1946, Adirondack spruce, which was used for this for all Martin guitars, was considered the best wood suited for guitars. Due to urban development and the clearing of forests during the war, Adirondack’s supplies were depleted and prices had risen exorbitantly. It was therefore replaced by the more easily available sitka spruce from Alaska.
Another change that took place around 1946 was purely cosmetic and did not affect the sound. The intricate herringbone pattern decorating the Style 28 was abolished because these guitars were imported from Germany, something that had now become almost impossible. Experiments were conducted with different types of bindings, but in the end plastic was chosen. In 1976, the herringbone motif was applied to all D-28 models again.
