Any ideas how he does it? I can do the old San Diego-type growl but this is really next level. So next level that I'm kinda afraid no one here will have any idea what to do haha. No harm in asking though.

My thought is that it could actually be massive, what with the double-notchy quality I hear. Or it could be FM, due to how smooth it is.

After looking at the Burial remix through a frequency spectrum there is definitely two peak filters and a notch being automated. Chorus could explain the smoothness as I've heard similar smoothness in Riddim sounds that use Chorus.
