A special roasting technique accelerates the aging process, yielding the rich and responsive tonal character of an older guitar. The technique gives the tops a slightly darker complexion that resembles cedar.
Taylor has applied its latest tone-enhancing design strokes
to the maple 600 Series guitars. The result is a transformation of
maple’s historically bright tone profile into a richer, warmer,
more complex voice. Players can expect a more musical,
more versatile guitar experience.
