Venom - Warhead - PTB табы

Okay here it is 
Venom's Warhead
it's my favorite Venom song and 
I couldn't find the tab anywhere 
so I decided to tab it myself.
So this will be a pretty rough
transcription. I will just be transcribing the riffs right now
later on i will make a better version
If you have any questions comments
or corrections please email me at
