Single Action Truss Rod

We use single action truss rods on all Macmull Guitars. That means that the truss rod is activated inside the cavity by turning it clockwise, but works as a passive "releaser" when turned counterclockwise.

The result is better neck vibration capacities and a softer neck when bending; the neck has an increased range of motion when acted upon by the strings bending, but not in a way that will alter the pitch.
