Based on our tried and true "X-Brace" design, Jean blended a non-symmetrical scalloped lateral cross-bracing pattern. This means maximum strength using the least amount of material. It's a build that allows even further vibration of the soundboard, while still offering a controlled bass response. The 40 Series are built in America using all solid wood, like all Larrivée's, and feature brand new upgrades like bone bridge pins, nut and saddle, diamond fingerboard dots and 18:1 open back tuners. Jean's exciting new design means a fresh new sound that is sure to appeal to traditional and long-time Larrivée players alike. The OM-40R is an all solid wood guitar with a Sitka Spruce top and East Indian Rosewood back and sides. The bracing pattern is X bracing while the guitar comes with a satin finish. The OM-40R has a bone nut and saddle with bone bridge pins. This specific guitar is fitted with the award winning LR Baggs Anthem to ensure that you get a natural amplified tone when plugging in.
