drums was a mix of drum samples from different packs from splice, i dont remember which ones guitars were amplitube, which is the amp sim i use the most also i got a russian big muff clone on the heavier guitars here and i use the earthquaker plumes on everything, guitars and bass lmk if you have any other questions or anything
but like for guitars i think the "right tone" is mostly about experimentation and molding it to fit into the context of the mix multitracking for this style works really well to make them big
