The Martin D-28 is an absolute benchmark dreadnought, and early D-28s rank as some of the most collectable acoustic guitars ever. When Martin introduced the D-28 in 1931, it laid the groundwork for where the acoustic guitar industry would go. Very few D-28s were made in the first several years of production, up until a switch was made from a 12-fret to a 14-fret neck in 1934. By 1943, other changes include a decrease in nut width and the use of scalloped bracing.
