Truss rod size


New member
Hey guys.  Just wondering what size truss rod is in a Warmoth vintage modern neck with the adjustment at the headstock.  What size truss rod wrench would i need?.. or would an allen key work as well and if so which size? Thanks in advance.
Truss Rod Adjust

Allen Keys:
Bass Necks, 7/32
Warmoth Pro Straight, 3mm side adjust
Vintage Modern, 4mm

Warmoth Pro Angled, 5/16 socket

It's not the size of your truss rod.. it's how you adjust it.

Thanks tony! I was wondering the same myself.  :laughing7:
Anyone who has a tilt-back neck, I recommend this wrench:

It's an excellent design.  Makes adjustments really painless
