I broke the nut on my Takamine GS330S. I am ordering a new one from Graph Tech. I am getting one for my Ephiphone G400 as well. There is a specific product number for the G400, so I am getting that, but there is none on there guaranteed to fit the Takamine. I penciled up the spacing on the Epiphone, and held it up to the Takamine, and it appears to match I also measured the height and width; they match.

Do you guys think I'll be okay to get two of the Epiphone nuts, they seem to be the same nut.

I don't have much experience with this so I don't want to deal with filing a blank.
