I follow a couple, not only guys that play but also for reviews or demos.
He does lengthy videos and talks about music and gear in a general way, shows off some guitars he has or some gear. Its basically what i call hanging around for a couple of beers and discuss Guitars. I like it
Australian guy that has some of the most amazing covers I ever heard, he does not only play them but sometimes we have the feeling we are listening to the original guy playing guitar, he captures nuances in such a manner its a pleasure to watch those videos, especially for the more known songs, Check the Van Halen, Maiden, Lamb of God covers.
Well... the dude is an amazing player and can really shred and he was now some kind of learning how to shred channel
For the amazing reviews/demos and great tunes he makes up for them
English guys that has very long videos on how he setups Guitars on his small shop. We basically see it all, disassemble of the Guitar, Adjusting the Neck, Fixing Fret, Issues with wiring etc. He has videos of hundreds of Guitars and talks about the construction quality and small issues that can fixed (or not). I find it a very informative channel.
-Charlie Parra del Riego
Great guitar player from Peru. He does comparison style videos (Metal vs Punk) or "metalizes" famous TV Shows themes or even video games.
English guitar player show some songs, demos gear.
-Nick in the States
American guy that has extremely informative and playing videos of Cheap guitars and he seems to be promoting Harley Benton's for their value attending what they cost. To him they are more than worth it and they rival 3-4x times more expensive guitars, and since not all of us have acess or can buy the top of the line I got interested when searching for Harley Benton reviews and found the channel.
Nice How to Solos from know tunes with tabs
French dude that reviews Tons of stuff. Dude is a bit crazy and it can get a bit over the top sometimes but he reviews and compares to A-B and C
Then there's the usual Ola Englund, Tone King, Ryan Bruce, Chapman, Keith Merrow that everybody already knows
