Warwick dual-action truss rods

[BoomBoomOGTL]

How do these work? I read another post on a guitar forum recently where the owner of a guitar w/a dual action truss rod (NOT a Warwick, mind you) thought he had a serious neck issue not being able to get any neck relief or back bow. He’d loosen the truss rod to the point it had no tension and the neck never would move beyond perfectly straight.

Years later, after retiring the guitar as wall decoration, he came to find that there is a loose (slack) zone where upon turning the rod beyond the slack zone, it then started to hold tension again, and at this point relief was being added to the neck.

Most (OK, all) truss rods I’ve adjusted are simple; one way tightens the rod, the opposite direction loosens it w/o having to pass through a transitional slack zone.

How do the modern Warwick dual action truss rods function?

I ask b/c I have a Warwick that has a neck as straight as an arrow. The truss rod had a decent amount of tension but as much as I loosen it, it doesn't introduce any relief.

There are truss rods that are dual action are the same as most 99% of other truss rods out there they can move forward for relief and back for pulling the neck back and taking relief out. I have no clue as the rest of what someone was telling you about Warwick necks. Could have been a neck “wood” problem they do occur on many basses and need repair beyond a truss rod adjustment.
