On the end of Riff3, I'm really pinching the pick to get that "pinch harmonic" you're hearing towards the end - Sounds pretty mean when you can do it on the low E. Very "Dime-Bag" esque. By the way, due to bandwidth usage on http://guitar-pedal.com, I had to set up a new site http://guitar-wav.com for my effects wavs and lessons.
