Troglys a bit of a doofus. I watch his vids because.... guitars. His narration and knowledge doesnt really garner any wisdom imo.
Also, that SG he's showing off has an issue that we've discussed here. The comb angle on that Maestro is wonky. That's usually found in the import knock offs but has found it's way on to Gibsons. I had an import that sits like that. I also had another import comb that I swapped it for. Problem solved.
As everyone mentioned, a knowledgable tech or luthier will set one up and it'll work great for what it's intended. They can take some abuse too. Plenty of vids of players going to town on 'em.
"there's a reason why people ripped those things off the vintage SG's and converted them so stop bars" - yeah, that reason was that they were either ignorant clowns or just didn't like the look. And you're right, that angle doesn't look correct at all.
