In my time with Taylor guitars, I have ordered six custom guitars, one of which I still own. These were all built from the ground up (not modifying a standard model). The issue I have is that the sky used to be the limit when putting one of these together. In fact, my first custom Taylor (quilted sapele top, back and sides) was done with a total body edge burs finish that I didn't order. Taylor just felt that the guitar would look better that way (and it did). It was the first total body edge burst I had ever seen on any Taylor. In those days, Taylor seemed to have more fun with these custom jobs, but over the years, many restrictions or limitations came into play, I guess to make their lives easier. I will say that Taylor's stock models' aesthetic appointments have become more exciting since then. To the OP's point, until Taylor does a better job with clearly stating what the custom guitar build options are these days, I'm out....
