I must agree with Francis here!!
I got a free membership for linking to them from my site (you can do the same!) and found 3 great lessons to take my playing to the next level in no time...
- Chord Inversions
- Speed Stamina
- Ionian Scale Speedpicking
I'm venturing into jazz while trying to also improve my technique at higher speeds.
In any case -- very nice site and not JUST lessons in the style of other guitarists, (which is what almost turned me off) but also straight-forward techniques, exercises and theory that can apply to almost any axeman.
Here's the link again
