The OOO model is essentially the same as my OM but features a 12th-fret design neck-to-body. This characteristic refers to the position where the neck meets the guitar body. The different positioning of the neck relative to the body shifts the bridge location closer to the center of the lower bout, which on the same sized guitar, will contribute to a more delicate, sweet and complex sound.
Traditionally, the join was always at the twelfth fret but the demand of steel string players wanting easier access to the higher frets resulted in the fourteen fret neck appearing on a Gibson archtop guitar in 1922. Years later, it was adopted by Martin guitar company in 1929 for its flattop OM model, and it afterward became the standard for the majority of production steel string guitars.
