Yeah, I know that was a live thing. In the studio rutan is pretty big on using his maxon boosts, I know that for a fact.
I’m not so sure about that anymore after hearing the greenback comment. Greenbacks have a pretty inherent sound, the second I heard that comment I was like yep… that’s the sound on the last several albums. Tone is darker than the earlier stuff. kill, bloodthirst, wretched spawn are very clearly a V30.
I know for a fact pretty much every cannibal album that rutan has been involved in uses two heads. The main tone is always a recto. One of which you mentioned blended with a mark V. The last two both blended with rutans Marshall that he used forever on all the hate eternal stuff.
