Ive been making some grime lately which im assuming is a pretty similar sound.
Cant tell you how to make the exact same sound as i dont have time to actually try it... but this is how some of the old school bass sounds were made
Record a distorted reese or any bass with a bit of low end as an 8 bar loop... the sound really doesnt matter too much here
you can also use a stretched 808 kick
Load it into your sampler
Slap on a low pass filter at around 70-100 hz
Put the resonance anywhere from 30-60%
Now you want to play with the attack, decay and release of the filter until it matches the sound you want...
You also might want to play around with a filter lfo to give it some extra wobble
With some samples youll need to change the pitch... normally up
Hope that helps
