hey i was just wonderin if anyone knew what pedals maket that high pitched screech that gojira makes and thats in the song duality by slipknot

Please and thank you
Erm, you mean pinch harmonics?

THEORETICALLY there are some pitch shifting pedals which can make the note go an octave or two octaves higher, but there is a method much cheaper and better for you, I mean of course learning how to create pinch harmonics with your thumb.

This guy explains you how to do it
