jeese ill like to drain his brain!
basically wheat i do is make 1 b line, normally using junglist , then make another one more subby to gove it bottom end, whack up on diff fx chans and eq then seperate compress eperate and blend them using teh volume till it sounds rite
works nice if u have one of c4 and one on c3 although the one on c4 alone may sound hi and shitty when it blends with teh other gives a warm full soundbasslines is one of themt hings uu can play with all day, when teh osund has merged into n unrecognisable noise, go get a coffee export and get back to
thats the best way imo
