So I recently got an Ibanez with an Edge Pro(great trem) but it has those locking studs. I don't even know exactly how they work(I'v seen diagrams and I dont know why a little stick is going to keep the stud "locked").
Point being, I need to lower the action just a touch, but every allen wrench I put in there either doesn't fit or spins freely. Some of the docs online i'v seen call for a 2mm wrench and I tried it and it doesn't move either side. What am I doing wrong here? I'm sure I have to unlock these before raising and lowering the bridge?

The guitar I bought was literally a 10 year old guitar new out of the box. Didn't even have pick marks yet. So I know they arn't stripped.

These locking studs seem like an unnecessary PITA.


Edit:I just noticed it was an edge zero doc that asked for the 2mm wrench, but I assume its the same locking studs they are using for all the trem lines?

Loosen the whole post, then you should be able to adjust the stud lock. Typically you would set the post slightly high, tighten the stud lock, then tighten the post down on top of it, locking it in place.

So can I raise and lower the posts without unlocking the stud lock screw? If I understand what you said, the locking stud screw is under the post?

 

[Toshiro]

It's inside. You'll have to back the post up to unlock it, then loosen it with a 2mm allen key.

Though, the Edge Pro did not come with them stock, only the Original Edge an LoPro Edge, so you shouldn't have them...

The stud on the left is from an Edge or LoPro, on the right is an Edge Pro, as seen from the bottom:

I'm pretty sure these are locking. Maybe not? They have a silver screw looking piece that is a separate piece(or at least a separate metal) in the center.
They are the same cosmo black/grey and not black like I think the locking ones are.
Its just that the amount of force I'm using to try to move the post seems excessive and it doesn't want to move. Like its locked. It feels like if i push harder, I'm gonna break it. I guess it could just be the stock ones, but i dont understand why I would need to use so much forced. I my experience, some most trem posts are hand tight when you take off the bridge and move easily with string tension. This just feels like I'm not unlocking something or something isnt right.

And pretty much across the board I'm seeing the opposite info that you have to unlock the stud locking screw before adjusting bridge height.

Pull the bridge, back the studs completely out of the guitar, and look. :lol:

 

[Reverend 7 Strings of Hate]

And what when I pull the bridge and the post keeps doing the same thing?

 

[Toshiro]

Even if it has the set screws the posts should back out without an issue. The set screws don't screw into anything, just press against the bottom of the insert.

Ok, so that makes me understand what the fuck the purpose is finally :lol: I thought that threaded in and I didnt get why that would help or how the hell that worked.
With that, I pushed a little harder and it started moving. I don't think this guitar was touched for 10 years, so maybe it just needed a little extra push.
Nothing exploded and my action is better. So thanks

that's an edge pro which doesn't have locking studs from the factory. you could order some from Rich at Ibanez Rules, unless someone put some in the guitar before you got it.

This guitar came with the reciept and there was a setup and something else written on the reciept that I can't decipher, but its possible the guy had that done. But looking around, I think these are the stock posts and they just LOOK like locking deallys because the different metal in the center.

Yesh, my 1550 has the same studs and I too thought they looked a lot like locking ones. I'll be ordering lockers and doing the mod.

 

[Reverend 7 Strings of Hate]

Is there anything to the mod or is it just replacing the posts with locking ones?

 

[Ezerath]

IBANEZ RULES!! tech - setup

Nothing really to mod, you're just swapping hardware in and out. Some chapstick on the knife edges is a good idea also.

Nice. Thanks for the link

I know this is an old post, but for the record, and folks like me finding it through Google, you need a 1.5mm allen wrench for the locking posts and a 4mm one for the actual height adjustment. Also the posts above in the photo are Rich's mod, not the original posts, IIRC.

Here's the edge manual:

and here's the text in case the link dies:

Stud lock (this is the reverse of what you want to do when adjusting the action. You can loosen the stud lock all the way and it will stop on its own when you get there, then you tighten when you're finished adjusting the action -Bill)
The Edge/Lo-Pro Edge tremolo bridge uses a stud lock mechanism.
1.Insert an HEX key wrench (1.5 mm) through the hole in the top
of the stud bolt.
2.Turn the stud lock bolt clockwise, tightening it until it contacts
the anchor nut and can no longer rotate.
※ The stud lock will be released when you loosen the stud lock bolt.

Adjusting the action
To adjust the height of the entire tremolo unit, use an HEX key wrench
(4mm) to turn the stud bolts located at the left and right of the tremolo
unit. (It is not possible to make adjustments for each string individually.)
Memo
• Make sure that the stud lock is released before you adjust the
action.
