So, after some time, I finally figured it out, I'll make the tab for 4 string bassists.
If requested, I'll make a 5 string tab, but it's fairly easy to figure out for the 5th
if needed.
Still working on the guitar tab, but here's areally good interpretation of the song imo.
If anyone wants to make a guitar tab out of these root notes, please do, it'll save me
trouble, thanks.

Tuning: Standard

Intro

G|--------------------------------|
D|-------------5~------8~-----8~--|
A|-------6~-----------------------|  Play this for the first "quiet" intro
E|--------------------------------|  When the horn basically comes in, quietly

The Real Deal riff everyone is trying to tab

Riff 1

G|---------------------------------------------------------|
D|---------------------------------------------------------|
A|666666666------------------------------------------------|
E|----------33333333-3-666666666~-11111111-111/22/333~-----|

If the slide isn't played, then it's this

Riff 2

G|---------------------------------------------------------|
D|---------------------------------------------------------|
A|666666666------------------------------------------------|
E|----------33333333-3-666666666~-11111111-111333~---------|

Intro Riff (3X) play with horn
Riff 1 (2X)
Intro or Rff 1
Riff 2 (4X)
Intro Riff (4X)
Riff 1
Riff 2
Intro Riff or Riff 1 (1X)
Riff 2
Riff 1 - End

If this doesn't sound right, then play them an octave higher. The only "iffy" thing
this tab would have to be the "111111111-111333 or 11/222/333" on the E string, if it
sound correct, play it an octave higher, basically a "33333333-333555 or the slide: 
on the D string. The order is pretty straight forward, listen to the song and time it
:) that's all, rate, thanks
