How can I tell if my guitar has Locking Tremolo Studs?

I tried to adjust the action on my JS1000. The stud on the bass side is very hard to turn.
I did not want to strip it out, so I stopped.

Is it possible that my guitar has Locking Studs?
It was made in 1998.

Quite possible that it does as they came standard on the JS's up until the mid-2000s IIRC. I'd suggest you check out the Ibanezrules.com info on the locking studs and get the appropriate allen wrench to loosen the bolt and make your adjustment.

I believe there's a smaller hex head inside the outer hex head of the stud, so if you look down into the stud you'll see another 'locking stud' inside of it that has to be loosened before loosening the outer stud. Am I right?

Thanks guys!
My guitar does have much smaller hex screws way down inside of the studs.

What is the purpose of these? Is it just to make sure that the studs do not self adjust under lots of trem use?

Monsta, it's so that the trem stud is better anchored into the basswood. Basswood is a softer wood and over time, the trem studs can create and ovaling effect on the hole into which they're set. This affects tuning stability and causes problems. As I understand it, to counter this, a metal set screw is set into the wood and then a locking screw is set into that. The actual stud then goes in and is much more stable and locked in to enhance the longevity of the stud's hole and overall structural integrity.

To make adjustments to the stud, you'll have to first loosen the smaller set screw with an allen key down into the stud, then you'll be able to raise or lower the stud, then you'll want to re-tighten the set screw. I believe Ibanezrules has a picture showing the 3 parts that make up this formerly standard feature.
