How do I get this tone?

[PFDarkside]

Red Hot Chili Peppers' "Sir Psycho Sexy"

I know it's probably a Strat, but what effect is on there? (Specifically during the chorus and verses when he's just hitting chord stabs... not the wah part) Is it a chorus? Flange? Phase? What are some estimated settings?

Thanks

can't remember the tune right now, but I'll give it a shot when I get home and report.
