Well, I messed up my trussrod!

[Eckie]

I have a Fender Jazz 24 and recently tried to adjust the truss rod - it was buzzing round about the 12th fret on all 4 strings when I lowered the action. However, the key I used wasn't quite the right size and now the truss rod hex head is chewed!
How difficult / expensive is it to fit a new one ?

Not positive, but you should be able to get a new nut that screws on the end. Just need to be very careful when you put the new one on not to cross thread the threads on the truss rod. If that happens then you just made it more complicated to fix.

its fixable, you just need a new proper truss rod nut(the head), you can buy them from stewmac for 3$
the same happened to me 2 weeks ago, any info you want just PM me
what kind of bass was it?

i am not sure how easy is it to fix yours, but the guy who repaired mine said that it was really annoying to take out the old truss rod nut, but he did it and for 30$ my bass had a full setup and some extra things the luthier added

Thanks for your help. Based on your advice that it doesn't sound too bad, I'm going to take it back to the shop where I bought it - they have a resident tech.

Sometimes it's possible, if you have the right size flathead screwdriver, to get truss rod nuts out with them. The nut is already chewed up, so you don't have to worry about damaging it anymore than it already has been. If you find a screwdriver where the blade is just barely able to fit into the diameter of opposite corners of the hex hole, or even one that's too snug and must be tapped in with a plastic mallet, you might get some purchase on it and be able to remove it. At that point installation of a new one is pretty easy.

1) you went the wrong way... 2) you adjusted the wrong thing... you should have raised the saddles for buzzing above the 9th fret...

Thanks - I'll investigate this further

Thanks but I was following what looks like fairly standard advice that I read in a couple of different books. The overall action was too high for me and I think its still pretty high but starting to buzz round about the 12th fret.
