Watch the The Warble online guitar lesson by James Hogan from 50 Jazz Rock Licks You MUST Know
Here’s a cool and easy signature lick for you. This one belongs to John Scofield and it’s one you’ll hear him play a lot. When ending a phrase on the low E string, instead of adding vibrato in a downward direction with your fretting hand push the string upward over the edge of the fretboard and warble your vibrato back and forth along the side of the neck. That’s it!
