Jeff is totally awesome obviously! And a very nice dude who we should reach out to.
But this is pure alternate and doesn’t really look or sound like Yngwie’s one-way economy approach. Again fabulous playing but not the same thing.
Re: the scalar bits and how the picking works, Jeff’s picking motion looks like Andy Wood’s and McLaughlin’ss. That means it’s DSX, not USX. So Jeff starts all these little six-note patterns on an upstroke. In slow motion this is clear. This is the opposite of what Yngwie does. Jeff definitely does throw in pull-offs here and there, but because he’s not using the full-time USX thing you’re not getting the little DDU combinations you would get with a USX approach inside the scalar lines.
Obviously, some of the arpeggio stuff is swept here for sure. But you’re seeing more of that “two way pickslanting” Gambale-style approach as opposed to the one-way economy approach of Yngwie or Eric Johnson.
Always happy to take a look, but I think that would fit better in a Technique Critique thread. For sure go ahead and make one, and link
More generally, have you watched the Cracking the Code episodes linked above as far as how the picking motion works, when to use pull-offs vs sweeping, and so on? Because the way one-way economy works is thankfully pretty straightforward. It’s based on USX motion, all these even-numbered patterns start on downstrokes, and so on. Just getting a handle on the “rules”, so to speak, can clear up a lot of confusion and save a lot of Q&A.
