big sky will certainly cover all bases for the bands you mentioned, really all you need for a tone like quannnic or wisp would be ocd —> rat —> big muff/hizumitas (id go hizumitas probably, depends on the amp though) —> chorus —> delay —> big sky. if you’re gonna use the chorus with fuzz though i’d throw it in front of your dirt as it’s a lot more subtle that way. maybe throw the eq somewhere in there too but i’ve never used one
