then the next riff

here he uses a space robot sound, he does it with his guitar synthesizer.
how to make the sound: you have the normal distortion sound, and then you put a
half step tuned up guitar sound with the first sound, so you play like 2 guitars
you can do this on: Digitech RP 2000 and more, unless you have a guitar synthesizer, so 
the riff just repeat it as many times as needed
