First of all...... Hell Yeah!!! I'm partial to a bit of riffage ;) I agree with Guitarhacker, either the facebook player is crunching the audio, or it needs a little eq tweaking. Sounds like it could do with a touch more on the top and bottom end to me. I think the overall levels in the mix are good, just the eq needs revisiting on the master channel. But other than that, I enjoyed the song and I'll look forward to hearing something with vocals on it.
