This angered a lot of people, because the Gibson Les Paul, and most specifically the Les Paul Standard, had always been Gibson's iconic solid-body guitar ─ the guitar that carried Les Paul's legacy and that had helped write musical history ─ and now this iconic solid-body guitar was not a solid-body anymore. Because unlike with the 9-hole weight relief, chambering really does affect the sound, causing the guitar to sound more akin to a semi-hollow-body guitar ─ it's not the same yet as with a genuine semi-hollow (like e.g. a Gibson ES-335) because a semi-hollow is essentially a box, made of laminated wood that is glued together like on an acoustic guitar, but with a solid block running through the center from the neck joint to the tail end of the body.
Gibson would however not be swayed by the negative reaction from the audience, and in order to appease the die-hard fans, they simply introduced a new model to the line in 2008, called the Les Paul Traditional. The Traditional was essentially a Les Paul Standard as they were made and sold in the 1980s and early 1990s, i.e. with the 9-hole weight relief, chrome-plated hardware and Gibson '57 Classic pickups. But the Les Paul Standard proper remained a chambered guitar, and was fitted with all kinds of new and experimental features, such as the Gibson Robot Tuning system, which later on evolved into the more compact Min-E-Tune system.
Ultimately, by late 2011 ─ for model year 2012 ─ Gibson decided to abandon the full-body chambering on the Les Paul Standard and adopted a new kind of chambering which they called "Modern Weight Relief"
, and which has in the meantime evolved into the so-called "Ultra-Modern Weight Relief"
Unlike what its name suggests, the Ultra-Modern Weight Relief is not just weight relief. It too is a form of chambering, because it also comprises tone chambers that distinctly affect the resonant characteristics of the body. You can hear the difference in sound in the above video of the Les Paul Tribute and Les Paul Studio, and the video of the Les Paul Modern, whereas you'll also be able to hear that the Les Paul Classic ─ which has the 9-hole weight relief ─ sounds identical to the non-weight-relieved Les Paul Standard.
Gibson's erratic management decisions ─ which included both the wildly experimental stuff they were putting out and the fact that they were changing the specifications all the time for each successive model year ─ in combination with some unforeseen circumstances that Gibson itself was not responsible for ─ e.g. damage to their wood supply by Hurricane Katrina ─ ultimately brought the company on the verge of bankruptcy around 2016, and its owners put the company up for sale.
The company was then sold to its new owners in 2017, and efforts were made to centralize and consolidate the production capacity of Gibson's electric guitars in Nashville, whereas earlier, the hollow-body and semi-hollow-body guitars were being produced in Memphis, at a facility that was way too big and too expensive to maintain ─ Gibson's acoustic guitars are all still being produced in Bozeman, Montana. Once all of the legal and financial concerns had been dealt with, the specifications of the guitars were revised with attention for what the customers and fans were demanding, and then ultimately in 2019, this resulted in the current catalog of Gibson guitars.
Mark Agnesi is the head of Marketing at Gibson under the new ownership structure. He's not unknown to the die-hard fans of vintage guitars, because he used to work at Norm's Rare Guitars in California, and there are many videos on YouTube of him demoing various rare and/or vintage guitars at Norm's. And, he's also known for always wearing a black leather jacket.
Not everyone likes him, though, and I have my own opinion about him. Some people consider him arrogant. I don't know about that, but I do think he's a macho with an ostensibly fake attitude, and he's not quite as knowledgeable about Gibson guitars as the head of Gibson's Marketing division should be. But hey, your mileage may vary.
This is a pseudo-campaign, supposedly on Twitter, whereby people would be asking for the return of what Gibson itself used to call "the shroud" ─ a protective folding cloth that was attached to the pink lining of the brown hard-shell guitar cases with three leather straps, and that you would fold over the guitar once the guitar was snugly placed into the form-fitting case.
The hard-shell case of my own Les Paul does indeed have such a shroud ─ or "blanket", as Lee and Pete call it ─ as do the cases of my Firebird VII and my 2002 "Pete Townshend Signature" SG Special, albeit that in the latter case, both the shroud and the lining are black, and the shroud has Pete Townshend's signature on it in silver.
Modern Gibson hard-shell cases no longer come with a shroud. The feature was discontinued around 2005, presumably as a cost-saving measure ─ Gibson hard-shell cases are manufactured by TKL and are themselves not exactly inexpensive either.
