Noic!
So, Amplitude seems to work quite well for you. Nice riffs you got going on there man. Though, I agree with speedy...too much mids/highs. Also, your kick drum seems to be "nowhere" around either - more gain for that bastard in the mixer.
I liked the main riff of this one a lot. It's packed with energy and lots of shizzlz. ;D
Overall, good going! \m/
