c-pig, of course
and some sort of solid state distortion
From what I've heard, the amp used on that record was a 6505, I use a GSP1101 for everything through a tube amp and can tweak to get close to certain tones, yet I feel I need a tighter/bigger pickup then a holy diver lol...
I was thinking of getting a Mikael Akerfeldt SE, yes I know I have weird taste in guitars for brutal metalhead, I find them comfortable and I like "pretty" guitars...
I was thinking the obvious choice would be an aftermath (at least in the bridge) as I'm not sure how tight a C-Pig can actually get, and if it can handle other styles of music, when i'm "writing" I mostly play slam death type stuff but throw in melodeath catchy riffs and use open chords and I like to write ambient clean stuff too.
The guitar should be pretty bright since it has an ebony board and a maple neck/top.
