Thanks Michael,
I was pretty much coming to the same conclusion. I think I go counter clockwise about 1/4 turn. It could be the nut, but I don't it was sold that way. I think, through my stupidity, I might have driven the string further into the slot. Although, I can't see any cracks in it, etc. If push come to shove, I'll go back to tech. Maybe I'll replace the nut with bone. I like to correct the stuff that I can myself. I'm building a guitar workshop in my basement. I have all the tools I need spread all over the house.
In any event, I love that darned guitar. I've played a couple of other Taylor SB's and didn't care for them. This one was just made for me. Funny how that happens.
