I´ve recorded with a Krankestein just once, both cleans and disto (rtms & leads) with fucking great results!!! TBH I was really impressed by the sound this beast delivers!
Let me show you how it sounds:
Disto clip
Clean clip
Mine sounds different then this, when i use these settings its pretty dark, could be the shit power tubes the guy has in it right now (Groove Tubes) I need to get a new set of Sov's for it.
