The FG850 Dreadnought is all-mahogany with mahogany body binding which gives it a warm, woody design to match the distinctive richness in the middle frequencies. Like all of Yamaha's newer FG models, it is louder and stronger in the low- to mid-ranges, thanks to cutting-edge acoustic analysis technology developed by the Yamaha R&D Division. Yamaha’s engineers have achieved this sound by utilizing analysis and simulation to arrive at the best bracing design without depending on tradition or guesswork. This analysis led to the development of a new scalloped bracing pattern that maintains the durability of the top board while bringing out the most sound the Yamaha FG850 has to offer.
