Re: taylor guitar question.....
Taylors are probably as consistent as any guitar made, since they practically pioneered the use of CNCs to shape the necks.
that said, we are talking about an acoustic instrument. I usually pick up a 714 when I get the chance, and although they're pretty consistent, I do notice differences in tone and setup.
my personal feeling is that Taylors sometimes don't have the "etched" top end of Martins, and sometimes don't seem to have as full of bass, thought the treble end is what I notice more. To Taylor's credit, though, I think they forced Martin to make their instruments more playable.
to me, acoustics, even more than electrics, have distinct voices. When I check them out, I just sit down and play, try different tunings, etc., play harmonics ...
I look for a certain vibe or "X Factor". If I can sit down and in the right space, and kind of get lost in playing, then I've found an instrument I could spend some years with.
I don't know if that answers your question, but I hope that helps. I've visited Taylor's factory, btw. That was interesting, very organized, and lots of nice wood around. Although I'm sure you'd prefer to buy locally, I'd suggest doing some pricing at both Bufflao Brothers and Chuck Levin's, two of the larger independent dealers. (BB may be the largest.) For instance, BBs price on the model I look at is about $400 less than GC.
