Most likely axe fx. I can definitely here a bit of the German cab or Metal 4x12 blend, I think this is around the time Acle got his and was talking on facebook how he was struggling with it, tweaking etc
Personally not a fan of the rhythms on this one, the 'Milton Cleans' are swish though.
Compare to the 2007 demo, Concealing fate Pt1 1:58 onwards, there is so much power behind that nasty ass groove, which was lost on the One album, maybe as a compromise because One is definitely a roomey, vibey album, lots of analog, lots of bass and real lows, very dynamic but loud.
