Been letting this sit for far too long. Ordered a neck check straight edge and fret file, both found on Amazon. They both arrived Friday. Funny, several people here and on other forums suggested getting the 3-in-1 file from Amazon instead of StewMac because it's just as good and much less expensive. I chuckled when I saw the package with the file, as it came from StewMac. Apparently, the same Gurian set I bought on Amazon they are selling for much more on their own site. I'm OK with this.
Going to try to get into the neck work this weekend. Need to order the HeadlessUSA part, too.
