The lower octave of this line simply ascends using a diminished scale -- whole step, half step, whole step half step. The upper octave, on the g string, is made up of minor seventh leaps above every other note. The result fits neatly over a C7 chord with a b9 and 13. You can offset the lick rhythmically, and slur the half steps; slapping it is pretty effective, too. The fingering can vary, but I usually finger the minor 7th leaps with one finger laid across the fretboard.

The nice thing here is that the lick is easy enough to master, as the scale is symmetrical. At the same time, the problem with it is that a symmetrical scale gets boring. But you can take the same idea of building one (or two) intervals on top of a scale in a number of ways, with interesting results.
