I must be safe and use only the original Gibson-branded screws that came with the official replacement truss rod blank cover (which I had engraved)....

Or else, it'll sound like an Epiphone!

I can tell!

I have some ultimate tone screws made from unobtainium. I would send you some, but they’re illegal to mail.

Be sure to get the vintage-correct ones. They're only $350.00/screw.

I only have the vintage correct for the particular guitars I'm swapping the official items on!

Thankfully, NOS Gibson robo-screws aren't of vintage value!

The resonance of non-ferrous screws versus ferrous is noticeable to the trained ear.

Now that's just absurd. You can get the cryogenically treated ones from Callaham for $340/screw, and you won't be able to tell the difference.

I tried with both sets of screws, and no screws, and let me tell you, there was a pronounced siblance on the guitar with the replacements installed.

I cried. I wept.

I waited for the second pressing to fix the problem.

Cryogenically treated? Those are crap. Gotta have vintage ones. It's the only way to get old-growth steel!

"old-growth steel" - I guess they stopped planting the good steel and now are relying mostly on imports. (;oD

It’s all in the Torque specifications. High carbon steel helps with the sustain. They need to be placed in the freezer for six months to emulate age, each week works out be around a year of added vintage tone. It’s a secret technique that you can’t tell anyone.

You're a lucky man to have figured this out.


Thanks for sharing!

Only pre-45 steel, can't have those atmospheric traces from the atomic and nuclear bombs!

For those playing through Fender and Mesa amps you will find solar power will degrade signal path and effect your tone. Marshall?

Also--a critical and little-known secret is the screw closest to the nut: if it's too long and the pointy end contacts the truss rod, the relational torque creates Eddy Phase inversion, which causes cancelation of the modial interaction of the Mass Principle.

This Phenomenon is named after Eddy Phase, a guitar tech at Gibson in the mid-1950s, who discovered this. It's a closely-guarded secret, so don't tell nobody.

Good point, Geno! Also, the angular displacement of the truss rod is significant. The convex or concave position of the rod with relation to the perpendicular frets will affect the sinusoidal frequency of all triads, but especially at 440 Hz. And, as we all know, most great rock songs derive at 440 Hz.

440...441...whatever it takes.

432 Hz, that way I say everyone else is out of tune. “o) It’s easier on the screws anyhow.


Actually only one guitar is tuned to 432.

BUT! The screw head slots must be properly aligned at 29* and 331* degrees (prime numbers) respectively to the truss rod, or you might as well just use something from Ace hardware screw bin. You're welcome.

* reverse if you're south of the Equator

"Eddy Phase"! Thanks for providing the name for my pre-Nuke surf band from Reno, Nerf Vada. (;oD
