Hardened Knife Edge on Edge

I'm slowly getting my ibbys to have the same action across all guitars. I'm tweaking truss rods and adjusting bridge posts. So earlier I was raising the treble side of an Edge and BAM! the bridge leaps off its tracks and is sitting way high and at a bad angle. I think, "what the [email protected]#$?"

Before:




And after looking around my floor to find the piece:

Don't do that. Why would you do that?

Re: Hardened Knife Edge on Edge

This is why you are suppose to take the tension completely off the bridge before making post adjustments. I'm not saying I haven't made small tweaks myself with it fully strung but it isn't a good idea. It's about 80 lbs of pressure when it's strung.

Re: Hardened Knife Edge on Edge

Actually, from what I recall reading somewhere on the forum, the posts are designed to be adjusted while under tension. This particular one was 24 years old though and finally gave in.

I might push the trem all the way down next time to lessen some tension, but I'll never completely detune, make an adjustement, and then retune. Again and again and again. Tweaking is pain in the @ss enough already without having to tune a locking bridge back to concert pitch 20 times at a sitting.

Thanks for the comments though.

I agree, it would be a total pain. I usually release most of the string tension but not all and then make the adjustment until it's roughly where I need it. Then I'll tune up and tweak it from there. Once you get the post set correctly the first time you really shouldn't have to be adjusting them very often at all, especially if they have a locking stud.

Re: Hardened Knife Edge on Edge

All completely unnecessary on any Edge [except EP2/ED3, they're junk]. They are absolutely made to be adjusted at pitch.

There are many reason the heads snap on these. Usually they crack vertically, that's the first one I've ever seen where the head popped off, but it's not like it popped off because adjusting it cut through it. Parts break, sometimes without reason, and when they're 20+ years old, you should expect some things need replacing.

Re: Hardened Knife Edge on Edge

I've adjusted my guitars at-pitch since I got my first Ibanez in 1991. Adjusting them can be tricky enough - if it had to be tuned/de-tuned every time to adjust the trem...? There's no way in hell I'd own these guitars, and I've got five of them now.

Every time I change my strings I service the tremolo. It must be maintained, which is to say that it needs to be cleaned and lubricated. Chap-Stick on the posts at the knife-edge minimizes binding against the posts. Periodic knife-edge maintenance, and removing the posts and using lubricant (sparingly! I spray it on a Q-tip and then apply it) on the post threads is also good practice... 20+ years later, my oldest Ibanez (an RG770DXLB) is in near-mint condition with all its original bits and pieces.

And as Rich said... after 20 years, expect some parts to fail. It just happens. Having been a fan of classic guitars for 30+ years, I've learned to take maintenance to the next level to keep my stuff in above-average condition. It takes little extra time and the long-term payback is obvious.

OMG I wasn't expecting to read that!

Does that include the Edge Zero and Edge Zero 2?
