Watch the Doobie Mod online guitar lesson by Chris Buono from Funk Fission

In the first set of four bars the original riff is basically cut in half with a whammy pre-dip into the Bbsus2 at the upbeat of beat 2 (see Fig. 1), which is then rung out with some reserved chordal vibrato via the bar once again. As always, in order to pull that off the whammy bar has to be nestled somewhere in your pick hand ready to go. Next up, this variation is the first time a riff idea is modulated, in this instance diatonically to the iv chord, Fm7, as seen in Fig. 2. Instead of literally moving the components of the riff up a perfect fourth (five frets) I went in contrary motion going down the neck for the Ebsus2 voicings and the ending low F octave lick in the first position. As stated previously, if you put the time in with the sus chords you’ll find that this is not as hard as you might think. Looking at Fig. 3 in bar 4 at beats 2 and 3 you can see where I use the punch comping technique to my advantage when playing staccato chord stabs on the offbeat 16ths. The punch is made on the strong beats allowing me to play those tricky subdivisions more accurately making for a very hip sound. Fig. 4 shows off my Hendrix/Curtis Mayfield-style comping ideas but with the Funk fission techniques added in, which helps set my chordal noodling apart from the rest. Notice how I utilize my fret hand first finger as a background barring mechanism so I add notes against the harmony contained within the barred notes.
