This guitar has a solid sitka spruce top with a mahogany back and sides. It also has a dovetail joint. Beautiful sounding with a gorgeous resonance and tones that will be with you till the end of time. All Tetons go through a rarification process (rarified tops and back). This is a natural process that doesn’t overheat or discolor the wood. Guitars are placed in a chemical free vacuum sealed environment that removes impurities and sap. This makes the wood much stronger and improves the tone and makes for a natural and better aging process. Most factories buy green wood and then bake it like a cookie to dry it. They vacuum dry the wood, no heat involved.
