you can however buy a "whammy" pedal for around $200.... I'm not really sure of the realism and quality of them... but I'm sure there are sound files of it in action on music123.com - and Steve Vai uses it, so it can't be total crap.
There are only two important things in life - There's music and theres girls, not necessarily in that order....
