While it is most likely what you think, just a thought here. When my 812ce was new it buzzed when playing a D note, and I thought fret buzz, but further inspection revealed a loose board related to the ES system, or a loose component on the board. It was replaced by the local Platinum level Taylor tech( not 2 miles from my house, I am so lucky that way) and has never been a problem since. Tracking down a buzz can be hard, but once fixed you will have a great guitar, and Taylor will take care of it. Good luck and report back please with the results.
