More than thirty years ago, Dana was engaged by a major American manufacturer to design a guitar sized between the OM and Dreadnought. The result, later christened the Jumbo OM, was prototyped and widely displayed in the late 1980s though not produced for a few years, until the founding of Bourgeois Guitars.

The 25.5” scale JOM guitar from Bourgeois Guitars represents the largest body style in the 0/00/000-OM/JOM sequence. Following the same profile as our Grand Auditorium, the JOM features a deeper side depth, bringing its overall air cavity closer to the realm of a Dreadnought. The JOM boasts a voice big enough to tackle just about any assignment and is also available with an optional cutaway and Large Soundhole.
