What Kind off truss is?

What kind of truss is and what key (allen?) have to use it?

Thanks

Is there an adjustment that accepts an allen key up at the headstock end of the neck?

Looks like the older Fender type that is adjusted with a regular flat head screwdriver, except the slots are worn down. The wear around the edges of the hole would seem to confirm that it's had a wide screwdriver stuck in there a turned a few times...

No, in the headstock there is nothing, is a 1973 neck (or i believed that)

Yep, if it's an older Fender neck (looks like one), it takes a flat head screwdriver, not an allen/hex wrench.

The other one looks pretty similar to me, except the "X" slots are worn down.

And the headstock (what significate have the numbers after the "pat"??

It looks like the one in post #6 to me, except yours looks like much of the nut has been broken off. Perhaps you can get the old nut out and replace it?

The nut is allright, the problem is the truss

Perhaps.

To me (a novice!!), it looks like your nut is broken. Here's a link with a variety of nut-types: http://www.stewmac.com/shop/Truss_ro...ting_nuts.html

Yours looks like the Fender one, with 3 of 4 pieces broken-off. In your 6:18am post (3 above this one), in the first picture, it looks like only 1 of 4 parts of the nut are still there. The one left seems to be "sticking out", at the top of the picture (but still inside the hole). If true, I'd suggest replacing the nut, and getting one of these: http://www.stewmac.com/shopby/product/6111

Naturally, it would be best if one of the luthiers/techs that frequent here could weigh-in!

Thanks, now have a more clear idea of that

But to change the nut have to take off all the truss rod, no?

I really don't think so, but beyond the above, you need "professional advice" (read: better than mine).

If my understanding is correct, and you simply need to "remove the nut", the trick will be finding a tool to get the old nut off. This is similar to those "miracle tools" you see on TV for removing stripped-screws, but there are a variety of methods. The techs have lots of tricks for that. I've focused more on the kind of nuts that an allen-wrench fits in (which can easily get stripped inside).

From the looks of the picture, you'll need to remove the bad nut with an EZ-OUT & put a new truss rod nut on it. Be sure to lube the threads a little when reassembling. I use NEVER-SEEZ, anti-sieze compound cuz it never dries out & doesn't migrate all over the place once you get it where you want it.
