You're going to need a bar that will fit the holes in the adjusting nut. I thought the nut was gone when I first looked at the pics, but it's there! Not all is lost. Just stick something the right size in there and turn it the same direction as you would a regular truss rod nut. Got a few pics of my Milenium and Firenza for comparison. If you are going to blame anyone for this, blame Eddie Van Halen. It's kind of his idea. It's a pretty solid design, just treat it like a regular truss rod. Righty-tighty, Lefty-Loosey!
