Watch the Double Jump online guitar lesson by Corey Congilio from 50 Texas Blues Licks You MUST Know

This lick starts off
with a double stop and then makes a big leap down to what I would call open E minor pentatonic.
Freddy often played in the key of E. He would play licks like this unaccompanied on acoustic which
is a must listen.

I've heard Stevie Ray Vaughan steal this lick a time or two as
well.
