I hardly ever use youtube for lessons, if i do its just for solo’s/really intricate stuff. Like Tom Saguto for Skynyrd solo’s! My favorite thing to do is watch live videos of the songs im learning and see first hand how its played and go off my ear for the bits they dont focus on the guitarist lol
That being said, before Ed King from Lynyrd Skynyrd passed away, he used to play all his parts From the original skynyrd records and record them on facebook for all his fans who had him as a friend. That way they knew the correct way to play
