Watch the Weekly Workout #16 online guitar lesson by Chris Buono from Guitar Gym Weekly Workouts: Vol. 2
Is it string skipping or skipping strings? To me, it's how the lick is constructed. In this case, Weekly Workout #16 is all about string skipped arpeggios in Am á la Paul Gilbert. This cool sounding I-V7b9 sequence will have you have stretching a bit, exercising a bit of legato as well as hybrid picking.
If you're just starting down the string skipping rabbit hole, I suggest checking out my Guitar Gym | String Skipping
Have fun with it!
