Watch the Creating 2 Bar Loops: 1 online guitar lesson by Robbie Calvo from Creative Looping Handbook

This loop is very simple and consists of four guitar parts. The main guitar part is an A chord that hammers on to a D/F#, then I add in an upper voiced 4th and 6th double stop and single note melody line from the A major pentatonic scale and a chugging A5/2 chord to D5/2. Pretty simple stuff, but it's the sum of those parts that make the whole work for a cool jam. I then used the A major pentatonic scale to improvise over the groove.
