I’ve been teaching guitar for a living for the past 15 years or so, playing for 23, and generally pretty diligent about practice and improving. My “chops” were pretty good before I knew about CTC stuff, but there were a lot of things that stumped me, equally in not being able to play these things and also not knowing why I couldn’t play these things. And also not being quite able to help my students as much as I would have liked.
I think I got really into all Troy’s stuff right when he started coming out with Youtube videos, and I found a lot of it helpful right away, and I think I became a paying member early on. I really can’t say enough about how much Troy’s work has opened up my own picking abilities, as well as my understanding of what’s going on with the pick and ability to teach more complex/advanced principles with picking. Plain and simple, I can just do way, way, way more than I could do before.
I do think the paid membership is very much worth it, as I think a lot of the free Youtube things are intended more to be like quick demonstrations of an idea, and the instructions and explanations with the membership material are very thorough.
I think Troy’s material is more about showing principles and systems and then the student/player has the choice of what they want to do with this stuff, how far they want to go with it, which things they want to focus on more. It’s a lot like widely expanding a problem solving toolkit.
Since it’s principle based I think the people who benefit from this stuff are willing to dig into things like details of movement, angles of the pick, get analytical and make observations, etc. I think the material is probably the least suited for people who think the simplest solution is always the correct one, or want to hold on tight to things like “well so and so didn’t know about that, and he played great, so why do I need to bother?” if there’s that kind of resistance to new ways of approaching things, it would probably be hard to get the full value of what you’re working with.
Obviously you’re not going to get many responses from people who REALLY DISLIKE the material on a forum for people who like the material. I actually appreciate the approach so much that I’ve kept my membership going for long stretches even when I’m not logging in at all or even working on picking at all, just because I want to support the work, and also just have access whenever I get curious again.
I think if you wanted to get a larger sample size in making your decision, maybe it would be useful to ask in other forums or facebook groups about people’s experience with the material and see what resonates, as the odds of hearing about negative experiences would probably be pretty low here on this site.
