Yamaha FS820

The new 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, a new and ideal acoustic structure that maintains the durability of the top board while bringing out the most sound the Yamaha FS has to offer.
