That it is.  I’m listening on a crappy phone speaker now, so let me hear it later on over some FRFR.  Very vocal & guttural in some spots.  Clean input, too.

Off the top of my head, I’d say you could get there with any of those, but it’d have to be very specific, capable & targeted devices.

Maybe not ‘just’ a fixed wah.  There are a lot of deep, crossing resonances sweeping through vocal formant territory.

If I had to venture a guess right now, a phaser AND a flanger (and perhaps a wah tossed in, as well).  Or two flangers.

The trick is to get the delays / phase all moving with one source (pedal), and crossing over each other.  Sort of how the Vocal mode in Q-Wah works.
