The OM-05 Mahogany Select Series Orchestra Model Acoustic Guitar is Larrivee's top of the line orchestra model in Mahogany. The guitar features all solid wood construction with a Canadian Sitka spruce top and mahogany back and sides. The attention to detail is evident from a maker who's been handcrafting fine guitars since the late '60s. Each OM-05 includes Larrivee symetrical bracing and a hand fit dovetail neck joint.
