Hey guys! I've been getting into darker dnb lately and i found a duo from my hometown who are making these nice growly basses. I'm talking about the main bass ( http://www.youtube.com/watch?v=TTvLmO_vL38 ). You can also hear this one as the first bass sound in Program by Noisia ( http://www.youtube.com/watch?v=vyrwMmsufJc ). I'm not asking for the exact sound, I would just like to know what the base for this sound is and how sounds like this in general can be achieved. Thx!
