Well you know what they say, What's the difference between a lawnmower and a Les Paul, You can tune a lawnmower.
My 2021 Gibson Les Paul 50's Standard stays in perfect tune no matter what I do to it. It is still strung with the factory .010 x .046" strings. The build quality and attention to detail is astounding on this guitar.
It was built on Thursday, June 10, 2021. (@DonO decoded it just by looking!!!!!)
Now, when repairing/setting up Gibson style headstock guitars, there are a few things that give them a bad reputation.
It took me a while to figure out how to cut the nut on a Les Paul to get the tuning stable. It involves cutting slots no less than about .004" larger than string gauge, a generous fall-away and a slight funnel shape on the tuner side of the nut.
Here's one of my setups on a typical Les Paul:
Once I worked these details out, I had no more tuning issues.
Having said that, it's a lot of tedious detail work to get the nut cut correctly and it takes me 3-4 times longer to setup a Gibson style nut vs. a Fender nut, due to all the oblique angles.
The stock, white Graph Tech nut on my new Les Paul (according to published specs Ginson is now using Graph Tech now at the factory) had all these angles properly cut.
This is a zero defect guitar...and it is priced accordingly.
I did not see this kind of work/detail in the "T" Series, Faded and Tributes that I purchased in 2016/2017.
I paid $749.00 each for two brand new 2016 Gibson SG T Series (at different times), $899.00 for a brand new 2016 Gibson Les Paul 50's Tribute and $1,099.00 for a brand new 2016 Gibson Les Paul Studio T Series.
The Studio was the best guitar of that group in terms of build quality and finish, and one would expect the build quality to improve on a more expensive product, but I did not like the narrow fretboard and slim-taper neck profile....just a personal preference here.
While guitars built down to a price point may - sometimes - surprise you in positive fashion, I find the better quality guitars (in the Gibson line) starting to appear at about the $1,500.00 range and that would reflect the current cost of a 2021 Les Paul Studio.
Everything I bought (brand new) from Gibson in the $749.00 - $899.00 price range (in 2016) was really substandard in terms of nut prep, fret work, overall finish quality, neck angle and attention to detail.
When things are made cheaply, to fit a preconceived price point, there are things that are compromised to arrive at that price point.
I've "rebuilt" or "corrected" many issues with a lot of guitars for clients - including some USA models - but I won't invest this kind of time and effort in "fixer-uppers" for myself any longer.
