It's tough to beat a classic like a Martin OM-18, especially one that combines pre-war build specs with modern techniques and the Custom Shop tonewood selection and careful attention to detail. The use of sinker mahogany isn't just eco-friendly, either. The reclaimed wood has some of the same tonal properties of old-growth trees used on the beloved guitars of the past. Compared to newer mahogany, the tone is a little richer and more nuanced, and when paired with Adirondack spruce, focused and balanced across the strings. This pre-owned 2019 model is in very clean condition, with no notable wear, a pre-installed passive pickup, and a great set-up.
