Watch the Tapping: Level 2 online guitar lesson by TrueFire from Play Rock Guitar 5: Lick Vocabulary
Tapping: Level 2 - Workout #2: 80 BPM is a video guitar lesson presented by Chris Buono and is sourced from Guitar Gym: Tapping.
When it comes to single string tapped arpeggio sequences Eddie Van Halen is the undisputed poster child for this approach. To get the right sounding lick Workout #2 injects a hammer-on at the end of the sequence. Couple that with a run on major chords in a I-IV progression and we're just missing the slightly phased effect Eddie employed when he usually played these types of tapping ideas (feel free to add the latter if you have the means to do so!). If you're looking for some EVH to reference in regards to what this Workout sounds like the choices are all over the Eddie catalog. From Eruption to Jump and a lot in-between - it's well documented and pretty awesome.
