Independent shopping perspective
Built for plugged-in performance and recording, the right-handed FSX800C pairs a concert-size, single-cutaway body with an under-saddle piezo pickup and Yamaha System 66 preamp. Its three-band EQ and selectable mid frequency let you adjust bass, middle, and treble at the instrument, while the onboard tuner keeps tuning close at hand. The solid Sitka spruce top and nato back and sides are described as clear and balanced, with rich overtones. A slimmer depth than the FG series and 20 frets round out the practical design.
