I've got a repair to do and I'm trying to figure out the best way to get the job done. Someone brought me their Fender bass with the truss rod bolt rounded off. And I mean round. I don't claim to know a lot about this yet and I've basically told the guy that he needs to be ready to either spend a lot of money having the rod removed, or replace the neck, but if I can find a way to help him out cheap, I'd prefer it.

So, is it possible to remove the nut and replace it with another assuming the threads are still good? Would one of those extractor sets work or do I need to goto stewmac and buy their rescue kit?

[QUOTE=Evan Gluck]Hi Jared,
which bass series is it? What wrench are you using? 1/8 3/16?
Best, Evan[/QUOTE]

It is a 5 string Jazz Bass. A close inspection of the nut reveals that is it nearly perfectly rounded out. It looks like someone used a small key and worked their way up. I tried a couple differant sizes just trying to find something that would even grab at all, nothing. The only thing I can think of to do is to

a. use an extractor bit, which could break off.
b. use a larger wrench and jam it in, but I'm not sure I like the idea of the amount of shock that might require.
c. file out a groove in the nut for a straight edge

But once I did, should I be able to unscrew the nut, remove it, and replace it? I've never tried anything like this.

Plastic sheath. I won't have it directly available for about 5 hours.
