A different truss rod

RobertW, TonyKgull,



IS A BI-FLEX TRUSS ROD THE SAME THING AS A “DUAL-ACTION” TRUSS ROD?
Not really but maybe kind of, sort of. It’s Tech Talk’s understanding that the phrase “dual-action” truss rod is frequently used to refer to truss rod systems that actually use two rods. That said, it’s possible that we’re entering something of a semantic gray area here, as Fender’s Bi-Flex truss rod can indeed be sensibly described as providing dual actions—force in one direction and force in the opposite direction. We wouldn’t get too worked up about it, though; suffice to say that a Bi-Flex truss rod is a single truss rod that efficiently provides useful corrective force for both concave and convex neck bowing.
