One piece neck with a modern 2-way truss rod? in Solidbody Guitar and Bass Chat Posted December 7, 2014 · Report reply I have looked all over and have searched this forum too and anytime I see an example of a one piece neck build - they go into the vintage truss rod, routing the curved channel, matching the curve on the skunk stripe.. I'm wondering why I couldn't do a one-piece neck and use a 2-way truss rod poking out of the butt end of the neck. Am I missing something? I've done the two-piece thing and would like to build a one-piece neck but I don't really care about being vintage correct and really don't want to build all of the specialty routing jigs I just want to make sure before I experiment that there isn't some structural or other reason that this is frowned upon. Thanks!
