I totally understand the disappointment that adam has. You have an expensive and very nice guitar that you are proud to own....then out-of-the-blue something appears to be not right, and it's not. However, as others have said, "mistakes happen," and they do. My 714ce had a cracked nut and I never knew it until I got it home. Talk about pissed...lol....Don't know if it was missed by taylor, happened after being shipped, etc., etc,........but they got me a new one very quickly...My advice: if you like the guitar and the problem is fixed......have a blast playing it....Besides, absolutly NOTHING made by human beings (expecially when a lot of it is made with their hands) is perfect.
Likewise, I've had the saddle slip out while I'm changing strings. You've GOT to put it back in just like it originally was......Also, I've NEVER done a setup every six months. Once I have a guitar setup, aside from something out of the Twilight Zone, that's how it stays. Don't change the saddle according to the season either. I hadn't heard of that before.
