The riff is great. Positively love the tone; it's got a fatness and attitude that fit the riffage very well.
A couple of things stand out from the song:
- The dry drum hits don't feel like they're part of the tune. They just seem to stand by themselves. It feels like a guy with a stick and a carboard box playing against a backing track. I like the phrasing of it, though.
- The stutter thing going on near the beginning of the tune. I've listened to that passage three times, and each time I hear it, I instictively spend a moment wondering what's wrong with my computer or Internet feed. Maybe if you left a little bit of level in the troughs of the stutter.
But I do like your tone. It's kind of explosive without being jagged.
