ive been trying with two slightly detuned saw waves and some chorus, distortion, filter, messing around with a bunch of things. and really wide detuned saw basses. im mostly using serum, massive x and just random effects plugins and the effects on serum. it just never sounds as deep and fat as it does in some of these songs. i can get pretty close though. im thinking i can apply this sound to witch house beats as well just by opening up the filter.
