Watch the DG's Boogie: Rhythm 4 online guitar lesson by Steve Trovato from Voodoo Blues
Begin this one using your pick, middle and ring fingers on strings 6,
5 and 4 respectively. The extra note is played on the fourth string between the basic riff.
There’s a lot to keep track of here but the rhythm sounds great when you get it
going. Once again, snap the bass strings for more punch.
