OK - if I understand growl right (that what a Fender Jazzbass can give), 
then still it is NOT the filter - its the oscillator waveform.

Quite nice examples are the darker synth basses of Steve Winwood, or 
bass of Bernard Edwards in "Your love so good to me" (yes, the bass 
player of Chic did one of the greatest synth bass licks I know - and 
sorry for these boring old fart examples).



Try this:
1.) Three VCOs, one with asymetric, not modulated pulsewave is very 
dominating, the others are saw and triangle but each of them gives maybe 
only 10% of the signal.
2.) lot of small manual given vibratos from the modulation wheel.
3.) Lowpassfilter (no matter which one) with only a little(!) envelope 
amount, little resonance; filter envelope is more a longer and piano 
like envelope.
4.) VCA envelope may be organ or long piano style but without release.
5.) Put some fat and nasty compressor on it (Edwards used a Urei 1176).

Now switch the compressors bypass on and off, and you will see, that 
especially the compressor raises the "growl" which basically was 
produced by the asymmetric pulse beating a littlebit with of the other 
low leveled VCOs.
