Look ma No Capo! This one sounds great without a capo. It opens up a lot of new options. The main arrangement uses open strings to great effect. Check out the lick switcher. There's some good ones in there. Some show you how to play the same phrases in a "closed position". This is a great exercise for your left hand. There's also some really cool Celtic style licks available. Simple ornamentation makes a huge difference in the sound. Not changing the melody much, just adding some spice. Use the focus feature and looper to nail down those hammers and pulls with your fret hand. Put in reps at a speed you can play cleanly.
