Hey Brad,
So starting in 2018, I began doing more advanced song tutorials. So now, there are two different types, beginner and advanced tutorials. All of the beginner tutorials use the 18 chords and 3 strum patterns. The advanced tutorials go beyond that. At some point, I plan to create an Advanced Course that will teach “everything else”.
But, that being said, if you’re trying to learn a particular advanced pattern, just let me know, and I can discuss it in one of the live classes.
You never fail until you quit!
