EGADS! Not another double thumb thread! I have been working on the standard sextuplet that Victor Wooten uses. Slap open string, left hand hammer two notes in succession, slap downstroke, slap upstroke, pop. I've got that one down pretty good, even on my six string. But now, my brain cannot comprehend how to extend this technique further. So, I need some guidance from you slap gurus out there. What can I do to take it to the next level?
