This is my interpretation of Slither by Velvet Revolver. I've tried it with my band and it sounds just fine. I know that there are no tabs up so this was my first time to submit a tab. Any mistakes please e-mail me at fungis@hotmail.com 

first of all it would make ur life easier if you drop D. 
The song is in D pentatonic scale.

I didnt even bother tabbing the solo because its a D pentatonic and you can just improvise to it. The rythm over the solo is the chorus. 

Order goes like this :

Intro x2
Riff 1 not palm-muted x4 with the verse Riff 2 over it the fourth time
Riff 1 palm-muted x4 with the verse Riff 3 over it the fourth time
Riff 1 palm-muted x4 with the verse Riff 3 over it the fourth time
Chorus x1
Riff 1 not palm-muted x4 with the verse Riff 2 over it the fourth time
Riff 1 palm-muted x4 with the verse Riff 3 over it the fourth time
Riff 1 palm-muted x4 with the verse Riff 3 over it the fourth time
Chorus x2 pause
Chorus x4 with the solo over it.
