Uh, except for the fact that Dead Heart and The Gathering are both Rectos...
Ok, ok, checking the old library...
Yeah I see what you mean The Gathering is surprisingly very recto. I guess my memory failed me on that one.
The Nevermore tone has some MB in it for sure but I hear a lot of marshall. Especially in the attack. The breakup sounds like a bunch of different amps at once. A quick check on the sneap board...

Sneap's 800, XXX, 5150, Recto, Krank on the new album. Probably a good indicator he used a bunch on Dead too...
Mesa Boogie offers great distortion but you pay a premium for it and it takes a good engineer to track it right. You can get that much gain out of a marshall, you just have to alter it a bit. Those old Morbid Angel recordings for instance. Why would you ever need more distortion than that? I mean you can hardly discern the picking at times...
There's nothing good about these amps, IMO. I've heard some decent tones from them, but never any spectacular ones...
WTF is marshall doing? Mode four? Ugh. Tone is a tough discussion. Most people are content with their amp modelling and multifx solid state stuff. I think it sounds horrendous but I've probably just spent too much time around tube amp nuts. What are some recordings where that came out good on? Satriani? Yeah but he's still running everything through a power tube section and that digital edge is part of his sound. The new Megadeth? Sounds ok, once again he's going into a marshall power tube section. Pantera? Umm, not really.
Old Metallica/Megadeth/Everyone in the late 80's - Jcm800
Carcass/The Haunted - 5150
Metallica's Black Album/Dream Theater - Mesa Boogie
Opeth Ghost Reveries - Laney
Opeth Still Life - Engl
New Killswitch Engage - Framus
I dunno, I think these are pretty good indicators... I lean towards the Engl/Laney/Marshall/Orange/Ampeg side but that's just my taste.
