I was asked to fit a Floyd Rose locking nut to this Warmoth neck.
I was slightly dubious that it would work, especially as Warmoth will not cut the shelf for a locking nut on their Vintage Modern necks.
Thankfully, the truss rod nut is sited well back from the nut so fitting the nut was not a problem.
The only issue was that the nut has to be slackened to adjust the truss rod, something that shouldn’t need doing too often. One of the Floyd Rose nuts designed for a bullet truss rod would have provided access but unfortunately they are only available in narrow widths.
