Bone nuts.

Im going to give the nut slotting a rest for now, Ive taken in all the advice and maybe try again some other time. I now have TUSQ pre slotted nuts, I ordered 4 and have a PB neck on its way shortly for an upgrade on my PB, so they will be handy for that. I've also come to the realisation that these JB kits use the same necks as the PB's. I'm fairly sure the JB necks on Fenders are 38mm at the nut and the PB's are 42, my kit JB has a 42.

That's true, although the Fender measurements were SAE ;-) As far as I know all PB bass necks are 42 mm unless you special order. I am not sure whether Adam is still doing it, but it used to be possible to order a 38mm Fenders-style bass neck. He warned me that it would take a while, and it did. Several months. But I got one. A maple jazz bass profile neck that is my current favorite, narrowly beating out my G&L ASAT neck.

I have been wanting a P-bass with a Jazz profile neck since I talked to a bass player in a local band who had an original Fender P-bass that had come from the factory with a J-bass profile neck. It's such a rare bird that it may have been an error at the factory (this was a '70's bass and QC was not always great...). I have seen P-basses with J-bass necks swapped onto them... And I came close to ordering a G&L with a P body and J neck....but was not living the dream until Adam enabled my GAS.

The lovely thing about building is creating your own rare bird.

Yes of course, the old imperial measuring, ive become so tuned in on the metric I had forgotten that America still works on the SAE system. I been restoring Bultaco's for years and with the metric system as a standard its a lot easier for replacing some pieces, brain locked lol.
