I just took delivery of a GA-5e with a cedar tobacco burst top. It provides a little more darkness to the sound than do most Taylors. Perhaps the word is "woody" but it's a great addition to the Taylor line since it provides an expanded palette to Taylor's sound. Great volume and sustain. I think you'll find the guitar to provides less brightness all across the range of the guitar.
And Tyalor does a wonderful job on it's burst tops. So if looks are important to you, I suggest you add a burst top. Very nice!
