Devil May Cry Devil Trigger Voice

Okay so. I have searched everywhere and everything, and even tried myself. but I CANNOT replicate this. please someone help me.

The only common-denominator between those two is a 50Hz comb filter …

(comb *track* 0.12 50)

There’s more to it than that.

Then the Vergil one. how do I replicate it alone.

Bumping this because I decided to return to this to figure it out.
