I wote these lessons here over a year ago and should help you get out of that "boring" chromatic practices.

I've been playing since i was 13 (Am now 30) and still use these exercises from time to time for warming up my hands and building speed. These same techniques can be applied to any scale in any key anywhere on the neck. Don't let all those tab numbers scare you...you'll see they follow a certain pattern.
