Modern Player Jaguar - Replacement Truss Rod Nut

Hey all,

I recently bought a MP Jag for a really sweet deal off Craigslist. Only issue I've got with it is that the truss rod nut is totally stripped out, and it could use a little adjustment.

My only issue with that is that it is a 5mm nut instead of Fender's usual standard English unit nuts, and I'm having trouble sourcing a replacement. Warmoth sells this one: Truss Rod Nut, 5mm Broached, 3/8" Diameter, 2 5/8" Long but I'm not sure if that one is appropriate. I'd hate to pull that nut out and find out I don't have a correct replacement.

Has anyone replaced one of these before and can verify that the Warmoth one is correct or point me to the right one?

Thank you!

 

Well, I don't know the actual dimensions, but I was able to replace the nut. Turns out the rod is a standard diameter and thread pitch, so I was able to replace the 5mm nut with a standard Fender bullet nut. The 5mm was the socket for the allen wrench.

The Warmoth nut should have worked just fine, but it was actually routed out just a shade wider than 5mm. I didn't notice right away and ended up stripping that one out just trying to tighten it up. Plus, the length was over 2x the length of a Fender standard nut, so it stuck out of the access hole in the headstock. Looked really bad and pressed up against the middle two strings. So, I decided to give a standard nut a try.

The standard nut worked just fine, but I found out the real reason the nut was stripped in the first place, the cavity needed a few washers to give the nut room to turn. Threw three #5 metric washers in there and it tightened just fine. Now I've got some great action on my neck and am super happy.

 

I think I read something about the factory where they were made shutting down and they never moved the MP production to another facility. It's a decent instrument. I'm going to swap out the jazz pup with a humbucker, and I'm slowly converting all the hardware to solid black (but that's totally cosmetic). Otherwise, I really like the way she plays and she's got some great tone.
