I know that there aren't many of them out there, which I hope means they are pretty stringent about who gets to be one. The closest one to me is about a 3 hour drive one way. I would almost rather just send it to Taylor and have the work done there.Here is a list of all their repair locations:http://www.taylorguitars.com/dealers/Repair-Centers/
Taylor isn't as "stringent" as you may think. There's a Taylor Authorized Service in my area that I wouldn't let work on any guitar. He's messed up a couple repairs/setups that I directly know of. This is the same tech that wanted to fix my brand new Gretsch Brian Setzer hollow body by running a screw through the Bigsby spring cup and into the top of the guitar. When all he had to do was move the tailpiece that holds the Bigsby to the lower bout (end pin) over 1/8". It was off center. Oh, by the way, this guy is also an Authorized Fender Service Center. Believe me, you better check into anyone before turning your guitar over for repairs and make sure they a highly recommended.
