Watch the 5-4-1 Shuffle Groove online guitar lesson by Andrew Ford from Bass Groove Survival Guide
Here is a medium tempo “texas” type shuffle. I like to use my middle finger on the right hand and several fingers on my left hand to help mute the notes and create that dum-da-dum-da-dum feel(ex). But do it however you feel comfortable. Focus on creating that consistent triplet swing with the drums. Its less about the technique and more about the pocket or groove.
