Derived from the FG820, which has the solid spruce top and mahogany back/sides, the FGX820C has a cutaway body and an electric system. Yamaha's proprietary under-saddle piezo pickup and System66 analog preamp ensure solid, plugged-in performance. Case sold separately.The FGX 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 FGX has to offer.System66 features an under-saddle piezo pickup developed by Yamaha. Controls include a 3-band EQ, an adjustable mid-range frequency control, and a precision chromatic tuner for optimum sound tailoring. The system is powered by easy to obtain AA-size batteries that provide a stable power supply for improved sound quality.
