Ran across this site today called SpeedPicking.com that actually looks pretty interesting. In their words:
The Speed Picking Workshop is for any Guitarist looking to vastly improve their Speed, Accuracy and Coordination using an alternate picking technique. The online workshop allows you to develop this technique using a measured and methodical approach. This method promises fast, solid and measurable results for the guitarist that demands real progress and has the determination and patience to achieve their goals.
Wonder if you could get the same stuff from a book… Check it out at: http://www.speedpicking.com

You could look at Troy Stetnia’s “Speed Mechanics”
I gave in and threw 20 bucks at it for the year. It’s actually pretty interesting. My initial reaction is “let me get to the more challenging exercises. Some of these are fairly basic and I should be challenging myself, not wasting my time with the more basic exercises.” I’ve come to the conclusion that this is a pretty arrogant thought. One of my biggest issues is discipline and consistent practice. So having looked through the exercises, I will start at the basic levels doing the open string exercises. I’ll report back in a few weeks to let you know my progress. Thanks for posting this!
Mark, I’ve been going through that myself. I was poring over some instruction books recently, and found myself going to the more advanced stuff when I realized that to get to the advanced stuff, I can’t ignore the basic instruction, even though I might already understand it to some degree.
Then I realized that experienced guitar players like me who don’t have much formal training (school or lessons) getting into any kind of regimented instruction are kind of like smart kids in class. They inherently “know” the thing being taught, but don’t quite know how to intellectualize it – and the sobering thought is that – at least to me – that’s what getting instruction is all about. So I too am swallowing my pride, and really getting into the early instructional bits – after all, we all have to learn to walk before we can run! 🙂
