Disagree. Liquid hide glue is crap, at least compared to real hide glue. Titiebond can be broken down just as easily as hide glue. Dunno what the suggestion about "card stock shimming" is about, but does not sound like a suggestion you would hear from a professional gtr tech.I STRONGLY suggest you use a liquid hide glue to attach a fingerboard. That way, if the truss rod breaks,it is simple to remove the fingerboard to fix the rod. Some wood glues cannot be softened with heat like hide glue can. You can get ready to use liquid hide glue at most hardware stores.
