ISIS's "Panopticon" tone. Any tips?

[Pelikanen]

I've tried so hard getting this tone but it's real tricky.



From what I've read it's a Mesa Boogie V Twin pedal into a Sunn Model T head (apparently the Marshall JTM45 is very similar but the Sunn has a master vol.). I have no idea what cab/speakers they used.

Any tips?

Bump.

Going off the end of that first song, I came up with this. Nothing special but it's somewhere to start. There's loads of very harsh upper mids which are quite hard to replicate-there may be some IRs out there which have that sound like a K100-V30 mix? It's probably going to take a while to find the right one! Good luck.
