I'd like to suggest Justin for guitar lessons, found on YouTube at:
https://www.youtube.com/user/JustinSandercoeHe also has a web site that covers all of guitar teachings (much more than on YouTube). Free of ads, no sign-in, and... no membership required, he "really" goes into depth in explaining, has more than 600+ videos.
