Folks, don't let the raggedy end-of-fingerboard turn you off! I had the same thing happen to me and it's an easy fix. Simply take a small hand file and smooth the section in question until level with the bottom of the existing nut channel
. Install a "faux" end-of-fingerboard nut and it will look great!
An apology to the OP...didn't mean to derail your thread. Just thought this may be helpful for those considering the neck as a project.
