Are there any sweep licks out there designed for scales as opposed to the usual arpeggios? I just wonder because it's something I've never heard.
What got me thinking about it was the way Zakk Wylde takes techniques associated with 3nps and applies them to the 2nps pentatonic ie strict triplet and sixteenth note patterns. If he can do that, then why not apply sweeps to pentatonic and other scales?
Hybrid picking may be close to this idea, but picking two strings in a downward mini-sweep isn't the same as picking three or more.
Anyway, just meandering.
