Easy to install requiring a straight slot. The strong aluminium casing adds reinforcement to a neck. Adjustment is smooth and easy.
‘Martin style’ truss rods must be installed with the open taped side down towards the back of the neck and the flat aluminium side up towards the fingerboard.
We recommend that the slot for the truss rod be cut 0.5-1.0mm deeper than the depth of the truss rod. A 0.5-1.0mm fillet of timber should be used to cover the truss rod and fill the 0.5-1.0mm space above it.
The truss rod can be glued in place with some epoxy glue on the sides and top only, then the fillet of timber is placed on top of the truss rod and held or clamped in place while the epoxy dries.
The fillet and glue are then sanded flat to the top surface of the neck leaving a flat surface for the fingerboard to be glued.
IMPORTANT – Do not allow any glue to go on or into the open/taped side of the truss rod or around the nut as this may cause it to jam.
