Topic: Speaking of Instructional Material...great free lessons!
I recommend all guitar players check out guitaraxis.com . The website is put out by legendary guitar educator, instructional video producer and master player Don Mock. In the "learning center" he has a bunch of free lessons on blues playing, rock playing and spicing things up with jazz concepts. The lessons are in audio, video and PDF format. He also includes free Jam Trax. If you dig it, I seriously recommend his video "The Blues from Rock to Jazz" and all of his books on target tones, turnarounds, scales, octaves and arpeggios. But definately check out the free lessons. They will improve your playing.
