For Guitar, I'd remove Rhett Shull, dude is just a YouTube channel hocking gear he gets for free. It used to be interesting when he talked about touring but now that he's a full time YouTuber and doesn't play live or touring he's just selling ads and his courses. Courses, which, frankly are not that unique or good.
I'd add a few different guitarists in here though. Paul David's genuinely seems like a great dude. Stewmac has fun stuff though it is generally driven around selling their stuff, but I think they're still highly educational most of the time. Emerald City Guitar's has some really cool videos now and again, and I dig their videos on some of the vintage gear they have and find inspiration in that. Gracie Terzian has great music theory videos, she's the one that helped me fully understand the circle of fifths. I also really enjoy Eric Haugen, he has a few courses on TrueFire now as well.
I also dig Alamo Music Center, watching Cooper shred an acoustic is always a good way to spend 10-15 minutes. Dude can play.
