Welcome to the Forum! As Ray pointed out, and as this website explains, there are a few different options for students. You cannot go wrong with becoming a paying student of Pebber's, but it is important to keep in mind that Pebber's system is very regimented and set up a certain way based on his 35+ years of teaching experience. A lot of students come in thinking that Pebber is there to tailor videos based on the specific "wants" of the student. Pebber does not give students what they "want," but I assure you: Pebber gives students exactly what they "need" in order to become a better player.
It sounds like you have watched several of Pebber's free YouTube videos, and that is a great start! I would suggest downloading all available .PDF's from this website, especially the "Daily Practice Plan/Routine." If there is anything on that sheet that does not look familiar, then try searching Pebber's YouTube videos for an explanation of a certain technique, or exercise. If not, then ask us here in the Forum; we are here to help you as much as possible.
It is recommended that you post a video of yourself running through some of these exercises. It does NOT have to be too long; a minute or two is fine. That way, Pebber can get an idea of where you are at.
There is SO MUCH material here. I've been a student of Pebber's since 2008, and I have 3 binders full of .PDF's, graphs, charts, etc.
MOST IMPORTANTLY: There is NO "graduation" when it comes to Pebber's lessons. There is always something to work on, something to improve upon, something to strive for. I suggest that you come in with a completely OPEN MIND, and take advantage of all of the tools here at your disposal. If you are comfortable with all of this, I strongly encourage you to become a paying student.
I hope this helped, Claus, and I look forward to seeing you in the Forum!
