The "Bloodbath Sound"

[I_Am_Legion]

I wondered what was the equipment of the band (especially Jonas Renske's coz i'm a bass player) that allowed it to have such a sound.
What is the model of the bass, the effects he uses, the kind of equalization, the amps used...
This rough and dirty sound is quite hard to imitate, so if you had any ideas or answers to my questions, please help me.

Thx
