I recently purchased an Ibanez Az 2nd hand via Reverb. When I went to give it a setup today I noticed that there was no resistance turning the truss rod counter clockwise. In fact, all turning it did was remove the silver part that the allen key inserts into.
I'm a bit worried because I need more relief (concave) in the neck and I fear the truss rod only can adjust the opposite way I need. Is the neck/truss rod an issue or am I being stupid?
Any help is appreciated. I've had the guitar for about three weeks now so I'm guessing it's going to be hard to return if the neck/truss rod is the issue.

and if I turn the truss rod counter clockwise, there's no resistance at all and the silver part comes off with a washer;

You have a few options
The easiest is to put heavy strings on in the hopes it pulls the neck into relief, might take some time, but often works.
The more complex way is to tighten the rod so you have a bit if back bow then level the frets like this. Now when you loosen the rod you should get a bit of relief. Its hard to know if this will work without seeing it though.

I would try giving it a little ‘help’ - with the truss rod nut off, deliberately bend the neck forward by hand and see if that moves it at all. Leave the strings at full tension. You could also try tuning it up higher than normal, probably to about G or even A if you think the strings will take it (safer with 10s than 9s!) and leave it overnight, also with the rod completely loose or the nut off.
I’ve just had to do this to a friend’s guitar - the neck was completely straight or even very slightly back-bowed with 9s and the rod loose, so I tuned it up to G, forced the neck forward by hand, and then put 10s on it. After a week it’s got enough natural relief that it plays fine tuned normally, and I think it will probably move a bit more. If it does I’ll go back to 9s.

I'm actually surprised the ibanez doesn't have a double action truss rod. I wonder if that's something they consciously did for the AZ line?
Although now if you go to their page for the same model the truss rod area looks different;
Does that mean they've changed the model to a dual action truss rod?
