That's a perfect response to a such a question.dont copy them man.
make your own bass. Make some sort of brand new vibrating bass wobble called a vobble or something
if you want a noisia style preset logikz pm me and ill send you 1. a sound engineer made me quite a few when i was building at his studio. did most my presets for me but tbh dont use most of them they are well dark
you dont necessarily need to use an lfo to get GDUB style "womp" noises
just get a nice sound using 2 oscilatiors and shorten the ADSR filter to
medium attack, short sustain and minimal release, play a few notes and hear the "whump" sound
fuck about with oscilators to make some jump up bass!
