so its screams you want is it well i got the craziest by far; found it myslef.
what you gota do is make a natural harmonic on the 15 or 17th fret on the G, B, AND E string; ya wana sorta barre those three strings but v lightly to get the harmonic; so you hit all the string and scoop the whammy down with the harmonic playing so its like a scream dive; go try it out; laters all
