I wonder does Huber test each Rim with his "Vibration analysis" to make sure each finished rim has the same vibrational characteristics as the pre war rim.?

I'm sure that they do, and in fact the "vibrational characteristics" are probably much better than the PreWar ones. Far as I know, Gibson never tested the vibrational characteristics (let's call them "VC"s) back then - they diodn't even know about it, so how could they tell whether the rims were any good, not knowing the VCs? I'm wondering if there is a unit of measurement for VCs, like vibrations per second/grams per square inch you know, this rim tested at 3500 VSG/in2, which is good - 2500VSG/in2 would not measure up. They probably throw all the ones into the dumpster that don't have the right VCs.

I will buy that for a dollar !

I dont think they are throwing them away, just using them in non Trutone models.

The unit of vibration resistance is "so many what-cha-ma-call-its per something-or-other". It's in the Gibson construction specifications.

Really interesting topic here. I wouldn't think they could test a single frequency for accuracy, they'd have to run a range. This would be a really fun experiment. Huber has some videos of the development of the trutone system. I wish I had studied that in college!

That explains why pre war Gibsons sound so bad and are so unpopular!

can any one say for sure is the wood used in these anything special such as submerged or very old growth wood?

You would test each one to find its resonance frequency. You could tap it and read the note electronically or you could excite it with a speaker and read it.

I would say they end up in Flinthills, but that might cause an uproar.....
