Hi guys. I need help with getting an effect for a song. It's called Citizen Erased and it's by Muse. At the start when the guitar starts there is sorta a squealing noise that sounds like a very high note. If you listen to the song, you'll hear it easily. I was wondering how you can get this sound. I have a ZOOM pedal board. But if I could just find out how this is sound is made then I can tweak it myself on my board. Thanks.

I think he's just using a natural harmonic, one of the higher harder to hit ones. when you said Muse i figured it be a whammy effect, i'm told he uses one... I know very little of the band though.
