Six Feet Under - Sick And Twisted Bass

I know this tab is not perfect, but it sounds good to me... and it's the first time I do
this, so give me some credit. If you want to make it sound better, you'll have to tune
down a few steps (haven't got a clue how many)

Guitar will do his thing a few times, then bass comes in, then start playing this:
-------------------------|
-----------------------3-|
---3-----1-----3-----1---| (verse & chorus)
-1---4-3---2-1---4-3-----|

When the other voice comes in, play this:
---------------------------------|
---------------------------------|
----------------------1--0--1----| (Aaah! I'll be your victim...)
-0~----1-0~---2-3~---------------|

------------------|
------------------|
------------------|  (SICK AND TWISTED!)
--0000-0-0000-1-0-|

Please rate, I really want to know if I did a good job on the first tab I've ever made...
