The FS830 offers rich overtones, greater depth and improved sustain thanks to the rosewood back and sides and special bracing. The appearance, with abalone inlay around the sound hole, is more luxurious and an obvious step-up. The small and thin body is perfect not only for female/young players but for intermediate to upper level finger-picking style players. This FS has louder and stronger sound 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 the new scalloped bracing pattern, an ideal acoustic structure that maintains the durability of the top board while bringing out the most sound the Yamaha FS has to offer. Case sold separately.
