just took a listen to that on spotify.....that is an awesome tone, i agree.
The only things i can hear wrong is there's a sortof smooth area in the upper mids that sould be grinding and biting but is just sliding around .
As far as space in the mix is concerned i'd say that it's pretty good at leaving some space in the mix. I'm not sure really, i've only just woken up and my mind isn't working perfect yet
Good call on the upper mids, that pretty much sums up what I mentioned about not liking the character of the distortion, but man does it fill shit up nicely!
Tone 2 sounds heaps better to me. Much more aggressive sounding, not quite as cutting as tone 1 though, but tone 1 definitely sounds weaker to my ears.
