Yamaha chose a solid spruce top for their FG820, due to its look and tone. Spruce has a well-rounded, articulate sound with excellent projection. These qualities have made it the undisputed leader for acoustic guitar tops. And because it's made from solid wood, the tone will age gracefully, with enhanced harmonics and greater tonal balance as the years go by. Beyond that, the FG820 boasts scalloped bracing, resulting in a larger low end and more projection.
