Dude this is a good question. I actually mixed TWO different bass drum samples.
I had dfh superior on one track doing the double bass, and a crappy zoom drum machine hitting at the same time.
It sounds a 100% better than the dfh on its own (which is not hard because it was machinegun city) but now it is passable.
Actually it isnt....yet. I do need to humaize it a bit, mess with fluctuating levels and add fx etc etc but dry it sounds like this (there is a double bass part about two thirds into the song):
