Watch the Octaves Down Under online guitar lesson by Corey Congilio from 30 Modern Country Guitar Licks You MUST Know
The "other" modern country guitar hero is of course, Keith Urban. Keith has been tearing it up for years and his early music is chock full of killer licks. This lick has some great repetition as you'll play the first idea in one octave and repeat in another. You're not repeating it verbatim, but you're hinting at it. The chord progression is G-D-G or 1511 in Nashville terms.
Here again, I'm using the Vox AC30 model to achieve the tone. This is certainly a more challenging idea, so take each section slowly then put it all together!
