Arsis Guitar Sound (A Celebration of Guilt)?

I have no idea about the gear used but i know they recorded it at winter sound and it was mixed/mastered at hit and run studios
 
If I remember correctly Jim had a Rocktron Voodu Valve running into something like a PA amp, don't hold me to it, but he switched to a Randall MTS when he got endorsed. He could have used something else at the studio though.
 
I recall Jim telling me a Marshall poweramp was involved. Wait, do they make those? It's been a long ass time since he told me haha
Maybe it was a JMP, actually.
