I think lots of people know about that, since it's such a major part of the history of how CLF "morphed" from producing early Music Mans into producing G&Ls. I have been playing Stingrays since 1988, and when I first picked it up back then, I had this history, including the finish issue, explained to me by my dad. I would think that on a hobbyist Website such as this, this would be fairly common knowledge. I have certainly seen it mentioned many times, at least.
One thing the video's narrator didn't mention, however, is the plethora of dealer rejects and customer warranty claims due to badly warped necks and other issues...and the reassembling of some instruments with the wrong parts during factory warranty service (including mixed up neck plates and/or bridges, i.e. serial numbers).
They have a very positive reputation for being such well built instruments...but if you actually look at the history, and have played a bunch of them from different periods, you should know that the CLF-built ones, while certainly the "coolest," were actually the worst built of any era of U.S.-made Music Mans. They were actually just very well designed instruments that could leave much to be desired in the area of craftsmanship/production. And these issues played no small part in why CLF "re-booted" with G&L.
And if you're a G&L nut, like me, you also know that early G&L necks are NOTORIOUS for getting warped. As awesome as all the stuff was that was cranked out of CLF Research, design-wise, and as untouchable as they can be when you get a good one, they were obviously doing something very wrong there as well. I have never encountered such high percentages of bad necks on even the cheapest, most awfully built brands, as I have on pre-EB Music Mans and '80s G&Ls.
i think a lot of players mistake an unusable neck for a neck that needs to be but hasn't been shimmed, both early g&ls and early musicmans are gonna have 3 bolts with microtilt, which usually meant little to no factory setup or minimal factory setup and a neck that people are going to jack up from either over tightening or through improperly engaging that microtilt.
In the 70s the microtilt would be brand new also, some newbie not familiar with it gets a new bass, doesn't unscrew that bottom screw and turns it and they've bored a grove into an otherwise good neck. A lot of factory guitars and basses before then and after then have shims hanging out in them, and those guys for sure wouldn't be shimmed
