The general recipe is stringy patch + heavy detune + distortion + reverb. Here’s a bit more detail with Primer:
Oscillator: Thin-ish pulse wave. Bit of White Noise.
Unison: 4 voices, 0 Spread, VERY heavy detune. Make it wobble like crazy.
Amp Envelope: Quick attack to get that bowed string attack transient, around 75 ms. Quick release around 145 ms.
Filter: Low Pass, Cutoff a bit below Noon, heavy Res.
Distortion: About half-way. Now you should hear the unison wobble fighting with the Distortion, in a good way.
LFO: S&H waveform modulating Pan. Medium-fast rate, pretty heavy amount so that it mostly resides in the far left and right, with a bit in the middle.
Reverb: Big size, medium mix
