Play the break in "Sir Duke". Primarily pentatonic but starts in the middle of the fretboard, goes ALL the way up and ALL the way down. Also lots of fingering options that helped me get more comfortable with all of the fingerboard. Play "All Right Now". Lots of cool stuff going on above the 12th fret. Play the bass break from "Pictures Of Home". Another fingerboard traversing extravaganza. Lots more like this. Oh, and "Come Together" starts on the "E" 12th fret and goes UP from there!
