This shred guitar etude is inspired by Paul Gilbert sixes. Basically, you go up six notes across two strings, then start the next six notes on the same string you ended the first group of six notes. Do this until you reach the top two strings, then go down in the same fashion.
This is played in the key of G/Em, and begins with the 3 notes per string F# Locrian mode/scale shape. It climbs up a full octave and then resolves to a G note.
