Morbid Angel guitar solo effect

[Pman]

for those of you have heretic, the last track of the album (born again) is the solo from Secured Limitations from Gateways To Anniahlation
what is in that effect?
its got like the harmony discretely panned right and left
but what else is going on there
it sounds so evil!!
for those who cant hear it, ive uploaded it here temporairly Born Again

Besides what's probably a H3K, "what else" that's going on is a genius doing what he does.
