Dual action truss rod made in Korea
A dual action (also known as two way or double expanding) truss rod is a more modern design. When adjusted, it exerts force on the neck in both directions simultaneously, pushing towards the fretboard in the middle of the neck and away from the fretboard at the nut and heel. This is so that more force can be applied by the truss rods and is particularly useful in basses with higher string tension, like a 5 or 6 string bass but works equally well in any neck.
