Try looking at you bass as three seperate layers instead of one sound. You have your sub range (30-100hz) mid range (100hz-1000khz) then highs(1000-20000khz)
If you frequency split your sound (various ways of doing this, just search frequency splitting tutorials and find the one that works best for you) you gain control of those frequency ranges separately giving you the ability to EQ and add fx to each layer without effecting the the others. You can mono your sub without the whole sound going mono. You can dirty up your midrange without distorting the low end and you can add reverb and chorus to the highs to add character.
You can also modulate the filters on EQ's etc seperately for those neuro kinda sounds
