The Shape of Things to Come



 C.F. Martin Guitar Shapes



These are various shapes in which the Style 28 was produced.


 

12 Fret 1-28, 0-28, 00-28, and 000-28, 14 fret OM-28, and Dreadnaught D-28



Until 1929, Martin guitars had necks with 12 frets clear of the body.  

In 1929, the Carl Fischer stores special ordered a tenor guitar called the Carl Fischer Model with a shortened upper bout to allow greater access to 14 frets clear of the body.  

Later in 1929, Perry Bechtel of the Cable Piano Company requested a fourteen fret clear six string guitar, and the Orchestra Model was born.  The OM-28 was soon followed by the OM-18 and the OM-18P Plectrum Guitar appeared in 1930.  In 1931 Martin added a handful of plectrum guitars in the C-1 and C-2 round hole archtop styles.  By the end of 1931, Martin had built it's last Plectrum Guitar.


By 1930, the Carl Fisher Model had become the standard 0-18T.  By 1934, what was formerly known as the OM-18 and OM-28 had become the standard Martin 000-18 and 000-28.



Here you can see the difference in shape between Martin's 12 fret and 14 fret bodies:
