Hello!
I want to recreate the patch to play the four first chords of this song, I think the chords are G1 B3 - A1 C#3 - B1 C3 F#3 - F#1 C#3 F#3 A3
Here is what I did so far on Serum 2 (but I don't mind to recreate it on primer), there is an evident huge amount of reverb but I can't manage to reproduce the bass sound. I think the waveform is a sine.
Thanks for your help!!

I've done a deep dive into this one, so I'll give a short answer and a longer detailed answer(it's still a bit off, but it'll set you on the right track):
Short Answer:
Those chords in the song are actually using a sample of a Youtube video from Abel Menoza(timestamped the part), where he uses the Rosin Bow preset on a Novation MiniNova and runs it through a Strymon BigSky reverb.
As far as I can see from his video, you were right on all the chords except the third chord, which has a D instead, making it - B1, D3, F#3
Suicide Boys don't appear to have pitched/stretched the sample much, if at all, and any difference is likely from the sample running through whatever processing they had on the master.
I think Abel Mendoza may have tweaked the Rosin Bow preset(I hear saw waves more than in the og preset) but here you can hear the original preset clearly and here is another showing it.. Next biggest aspect in how different it sounds in those is the Strymon BigSky Abel uses, which is a very expensive reverb effect pedal. Also note the low end doesn't ring out with the reverb, I think this is due to the tone knob on the Strymon that gets it to focus on mids/highs only.
Longer Answer:
Here's a sample of my attempt:

Here's the Serum preset + an Alternative preset that might be better for tweaking:

It'd be very hard to match the BigSky reverb with basic reverbs but looking at its settings from Abel's video, we can try pull out his parameters(roughly), which I think are:
BigSky has a couple of parameters that a some reverbs don't, so I've left them out, but there was some high dampening and I believe a lot of chorus modulation.
It has a sort of tremolo effect you don't notice as much until the reverb tail but the original Novation preset has this tremolo built in that you hear in the example videos. I tried to approach it a different way because it didn't sound the same, so I used an LFO on the reverb wet and a little on the Osc's and put a delay after the reverb.
It'd take too long to explain each part of the setup in detail so I attached screenshots for any others that want to try recreate it outside of Serum, it'll show the most important parts of it but doesn't cover some slight LFO modulations.
Worth Mentioning:
I think if you play around with the preset and add something like Valhalla Supermassive(free reverb) in place of the Serum hall reverb it might get closer - I tried to keep it all in Serum2 for ease of use. Mine still sounds a little sharp and attempts to smooth it didn't get much closer. With a bigger reverb like Supermassive, you can instead try to recreate the sound of the Rosin Bow preset and run it through that - I took a different approach as Serum's reverb was a bit more limited so I tried to design the sound into it's reverb which isn't what the original did. Hope it sets you on the right track at least!
