I've just found Troy Grady's "Crack the Code" series and I was wondering if anyone has ever bought any of his materials and found them useful? I'm interested in the idea of someone breaking down the mechanics of picking but the website gives off strong snake-oil salesman vibes. The other thing is that I can't imagine anything ground-breaking that guitarists don't already know, and his "pickslanting" series seems to just be a 5 hour elaboration on economy picking from what I've been reading. I'm a decent enough guitarist, but I've been struggling to push my sixteenth note scales past 195bpm and I'm not sure if this is a technique issue or if I just need to practice more. (I've been easing off of metronome practice to learn more songs recently.) So I guess I'm getting a little greedy and looking for "secrets" when I should know better... Anyway, any and all opinions are welcome!
