Hey all. This monster is a combination of first and second mode of the C major scale and the tapping part is the second mode of the pentatonic scale. It sounds pretty terrifying when you add the 2 together and as well it gives a different kind of feel and sound to your playing. It's always a good technique to combine the 2 or 3 different kind of scales together , cause the possiblities are endless and you really can sound a lot different than many other guitar players out there. I am sure you know how to go about this , start with a metronome slow and shred your way fast up there. :-)
Until next time.
