i used ns guitars vocal chain that i found on this forum for screams on the clean vocals as well, i tweaked it a bit, i saw that brian hood said to ns guitar something like "ohh thats my exact chain as well" so i was like yeee ima doo that too. so basically like a bunch of limiting, two vocals. but it starts with the source . i saw you used the sm7b but you still have the filter on it in the picture along with a pop screen. take the filter off and just use the pop screen and keep the vocalist really close right in front of the mic. i just kept the main vocal completely dry, and the double a little bit lower but with a stereo doubler on it and tons of reverb with a long tail. and then i bussed them together and but a plate reverb i think and probably some ping pong delay on that buss as well. i used an seventh circle n72 mic pre cranked the midrange colour , hmm also i used the se reflexion filter with my sm7b
