Duude...
Your bending the strings WAAAY too much, it makes the opening riff sound like a horrible accident..., plus when you get distorted, it all just becomes weak...fazy, and just not a lot of power behind it...UP THE VOLUME ON THE DISTORTED GUITARS!!! MAKE IT BOOM!
And again, don't bend the strings so much on that "whaa" in the riff, it makes it sound out of tune, or something...that's all really...Great job FUNKBrs
