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

Getting back into the riffs we have Doobie Mod, which pays homage to that ever-so cool chordal hammer-on from a five string bar to a drop 2 m7 voicing (in this case Cm7) as heard in the classic “Long Train Runnin’”. This endearing move has graced many other rock anthems including Boston’s “More Than a Feelin” and Van Halen’s “Runnin’ With the Devil”. Hopefully this riff stands up to the coolness of these legendary tunes albeit my title doesn’t have a g cut off from the –ing suffix somewhere in the title.


This riff serves as the first example of superimposing sus chords with the Bbsus2 taking the Cm7 vibe first laid into you at the downbeat and making the overall harmony hint towards Cm11. Remember, you have to analyze the chord tones in the superimposed chord against the root from the primary harmony’s root, in this case C. So that makes Bbsus2 function as so: Bb = minor 7th, C = major 2nd or 9th, and F = perfect 4th or 11th.
