The Evolution of the OM


Since its inception in the later part of the 1920s, the Orchestra Model has gone on to contribute to some of the most vital and fundamental changes in the design of steel-stringed acoustic guitars, alongside itself becoming an iconic and instantly recognisable instrument with many twists and turns in its own captivating journey.

In this feature we take a look at the history and impact of this much loved design, as well as the evolution of the instrument over the years; from the original versatile bandleader through to the nuanced, finger-style tailored iterations in contemporary luthierie. 

It all began with a letter, sent in 1929 by Perry Bechtel to C.F. Martin, detailing a special order for a steel-string sporting a longer neck affixed to their largest body size at the time, the 000. Upon accepting this order, foreman John Deichman designed the guitar we now know as the OM, the first to ever sport a 14-Fret neck join, long scale and the distinctive attributes that come hand in hand with these crucial specs.

The guitar was dubbed the ‘Orchestra Model’ to appeal to band leaders and rhythm players for a role previously dominated by the Banjo, with the extra volume and focus granted by the scale length and neck join making for a guitar that really shone in the centre of such a mix. 

This new design was so successful, by the mid 1930s Martin released ‘Orchestra Model’ versions of a number of body sizes, including the newly released ‘Dreadnought’, pertaining to the altered specification. The 14th fret join eventually became standard in the steel-stringed world, and it wasn’t until the late 1960s that the Orchestra Model became the specific, tried and tested Acoustic Guitar that has appeared on countless albums and live recordings since! 

Here’s a look at some of the wonderful examples of this storied silhouette, and the distinct character each luthier has brought to the OMs story;
