A quick history of the Truss Rod

The Truss rod first starting showing up in guitars around the 1920’s. Thaddeus McHugh, a Gibson employee, came up with the idea and filed for a patent. Since the first version came out, there have been many upgrades to it. From T-bars with no adjustment built into it. Next was single action rods that worked one way. Today we have two way rods that will fix most convex or concave bows.
