i need to know how i can easily get the tone of the death metal band evocation.

i own a ibanez rgr321, a boss gt8 and a hughes+kettner 60dfx.

it would be awesome if someone also knew the tuning. i am not sure if it is standard c or d or even b.

well i try to figure out everything myself but some help is always nice.
oh yeah it says "Sounds Like: Death Metal in B-flat" on their youtube channel.

i didnt think of looking there. thank you.
