The Nut was the original and was not tampered with and was the recommendation of the “Martin Authorized” Luthier that I use. It plays well now but I might take a chance and try the D’Addario strings that were recommended at some later point. I have read some of the SC literature regarding their guitars and it is not that unusual for a guitar to move around early in their life until they settle in. This is my take on what SC says on their website
Thanks for you input
