Texas Blues Guitarist Rev. Muddy ( .texasbluesguitar.net ) shows you where the King of the Blues gets many of his trademark licks and tricks. It's called "The Sweetbox" and it's always in the sameplace no matter what key you are in. All you do is go to your Root note on the B string with your index finger, then put your middle finger on the G string one fret in front of your index finger and BINGO! You simply make that little 2 note chord and then use your ring finger and bend the B string from 2 frets in front of the root note. The Possibilities are endless! It's all in my Blues Guitar instructional video called "Texas Blues Guitar with Dennis Dullea" It's available here texasbluesguitar.net
