Watch the Double Thumb Technique online guitar lesson by Stu Hamm from Stu Hamm U: Slap Bass
Here is a style made popular by my friend and astonishing bassist Victor Wooten and used by just about everyone these days. To keep up with the latest and greatest I suggest that you get comfortable with this style and make it your own. Once you get the hang of it, there are just so many cool triplet figures you can create.
As always, start slowly until you get the hang of it, then release the Kraken!
