Flangery effect and how to get it


New member
Hey guys,

I like a lot to redo musics from artists that I admire, as a source to learning how the music structure was made, the effects, mastering and everything..
Last week I started to remake a music called "Sexxx Dreams" from Lady Gaga (produced by the great DJ Snake), and right at the beginning of the song there's this Flanger-like effect that I can't get to the same timbre. Tried so many things already that I'm really lost on how they made it.

Here is the song on youtube

Can anyone give me some light on how to achieve this?

Thank you!
