Been trying to give my Gibson Les Paul a perfect set up but really struggling with the action. And despite at this point having made the action extremely high, every single fret on the top three strings is still buzzing to an unacceptable degree. I watched this YouTube video:

and the guy said the distance between the top of the first fret and the bottom of the Low E string should be about the size of a Heavy pick. The first picture shows the distance between the first fret and the low E string with a two millimeter guitar pick for reference. The action around the first fret is too low to fit the guitar pick inbetween the string and fret.

The guy also said the distance between the twelfth fret and the string should be about the size of a nickel. The action around my twelfth fret is too high to fit the nickel. (see picture two)

The third image shows just how high I've made the action and yet the frets are still buzzing like crazy.

The fourth image shows the distance between the eighth fret and low E string whilst holding down fret one and fret seventeen. This is to demonstrate where my neck relief is currently at.

The fifth image shows my whole neck to also demonstrate the neck relief.

I have tried about a million different bridge heights and am still experiencing fret buzz all over the top three strings. Also, the bottom three strings are mostly good and not buzzing, however I would say the string is still a little low around the first fret on the high e string and a little to high around the twelfth fret.

Nut is also shown in the first image if anyone thinks that is a problem.

Sorry for all of the reading but I wanted to get across as much info as possible so I can get accurate help. Feel free to message me if more pictures are needed.

Thank you!

Very low action on first fret but very high action on twelfth fret. Every fret on the low E, A, and D strings are buzzing, despite raising the bridge very high. Please help!!
