Ibanez Edge original Bridge height adjustment

I have Ibanez JEM 7v and I wanted to adjust the action by adjusting the screws on which the knife edges pivot
I wanted to know the precautions and steps required to do the same and also which allen wrench to use

Re: Ibanez Edge original Bridge height adjustment

Most important:
slack the strings first. Turning the stud with full tension is bad for the knife edge and groove.

Second most important: Figure out if you have locking studs!
Try gently to raise the bridge by backing the post out a bit(one full turn is enough and makes it easy to restore). The reason for this is because IF the studs have locking screws, and they are tight, trying to go lower will probably snap the post top. I'm not sure on sizes, but the locking screw(if used) will be small(like what fits the saddles on a Fender Strat). With the stud able to turn without force, you know the locking screw is not locked(bottomed out) so you can stick in the tiny allen wrench and back the locking screw out a few turns. Once those are backed out, then you can do the height adjustment(I think that's a 4mm). Once you get the height set, then tighten those locking screws in till they hit the bottom of the insert.

I say "if" because some years have the locking screws and some don't. To be really certain, next time you change strings, with everything loose, its easy to back out one or both studs and look at the bottom(the locking screw is hard to miss). If you want to see what I am talking about, here's a pic.

Re: Ibanez Edge original Bridge height adjustment

Hey, I am really sorry for replying late. I was not around my JEM for a couple of days

I have figured out that my guitar has locking studs.
When I slack my strings the springs at the back pull the bridge back and the studs dont move because they are tight
Can you help me with this.
How to unlock the studs and lock them back in position?

You don't have to slack the strings with an Edge, the knife edges are quality enough that they can handle the height being adjusted under tension. The advise to slack the strings on a lower quality bridge is sound, but a bit overkill with a good quality bridge

Re: Ibanez Edge original Bridge height adjustment

Yeah
Thanks for letting me know that i dont need to slack the strings(saves a lot of effort)
But the thing is whenever i put the allen wrench inside the locking stud, it doesn't move
It doesn't go either up or down
I am using a 2mm wrench.
I want to know if there is a way to unlock it first so that it moves up or down.
It feels like they are stuck there.
They only move when I remove the whole bridge out but when I but the whole bridge back in position,
the position of the screws gets ****ed up.

Is there a way to move the height screws with the bridge in position or do I have to remove the bridge every time, because removing the bridge is a tedious thing.

I agree, it's overkill with an Edge trem.

I own a 1996 UV7BK and a 1997 JPM, both with Lo Pro Edge. To this day, I never slacked the strings.

I used the 1.5 allen
but i think its pretty loose

If I am doing anything wrong, pls suggest the correct method
I am a bit poor with floating trem adjustments.

Re: Ibanez Edge original Bridge height adjustment

You're not seating it in the set screw, you're definitely not seating a 2mm as it won't fit.

Are you saying that the allen didn't insert well into the screws to turn it?

Okay so I understood my mistake
The wrench fits*😅

Can you tell me if I go clockwise or counterclockwise to lower the bridge?

And also can you explain to me if there is a different procedure altogether to adjust locking studs and the ones with no locking

I mean locking studs and the studs that dont have locks have to same procedure to adjust their height?
