I've got an 808 sample pack and granted it doesn't have every sound that an 808 can make, prolly not even close, but there's nothing even a little bit like that "Dooo" kick in there, so I'm guessing at least heavy processing is involved.
I've tried layering 808 toms over a kick, didn't really work. Tried saturating the high end of the kick, also didn't quite work but there's a lotta ways to go about that, so I could keep trying I guess.
A basic question I guess would be: Should I try to get at this sound with synthesis or fucking with 808 kicks? In my experience syntesizing a PROPER 808ey 808 kick/sub is harder than it seems, definitely not just basic sinewave pitching downwards stuff.
Also anyone got that perc in Clipse - Grindin that's been rinsed to fuck, also in loads of fuccboi grime soundcloud tunes haha, you know which one I mean.
