Taylor 616CE Spruce/Maple Grand Symphony - NaturalTaylor's Grand Symphony shape yields a beefy acoustic sound with extra low end horsepower. Coupled with the package of tone enhancing strokes brought to the maple spruce 600 Series, players can expect impressive richness, volume and sustain. Design nuances include a back bracing profile that's optimized for maple and a special seasoning process for the spruce top called torrefaction to produce an aged tonal character with greater acoustic resonance
