Should a pro fix my nut or can I do it with a YouTube video?
While I was playing my 5 string, the nut randomly snapped/caved in underneath the D string. While making this post, I realized a piece of the nut fully popped out (as shown in second photo).
I haven’t repaired anything on my guitars before. I don’t know if I can salvage this or get a new nut, and I don’t know if it’s a home fix or if I should pay a pro.
Help me Reddit! Thank you
