It is hard to tell exactly. I hear some heavy chorusing. You might want to try the harmonizer detune instead of chorus. Maybe with the Micropitch algo but I think it can be done with the H910 algo also. Set mix to 50% and then detune pitch A with 9ms or so. Or set pitch A to -9ms and pitch B to +10ms.
It’s a nice example because you usually don’t hear that kind of sound in punk music.
