Kinky Afro

I used the tab that's allready here, but it didn't sound accurate. So i tried some
because the progression suggested seemed as a good base.
It finally came out it was good, but the tone was wrong, it actually is one full tone downwards.

So the thing is like this, the whole song goes with Gm - C7 with the main riff like
Riff 1
e--------------| 
b--------------| 
g-5^7--5-3-5---| 
d------------5-| 
a--------------| 
e--------------| 

After the chorus:
Riff 2
e-------------------| 
b-5----6-----8------| 
g-7^9--8^10--10^12--| 
d-------------------| 
a-------------------| 
e-------------------|
