Really the same as any reese but with a square wave instead of a saw and the fundamental is done separately with a sine wave.
With an additive synth like sytrus you can do this in 1 patch but to make life easy you could do a bandpass on the reese to filter out the fundamental (maybe use key mapping)
and the Sine wont need a filter

GL. Let me/us know if this makes sense

"Classic" electrical power hum....as heard in many movies when close to evil machinerie ;-)

Another (simpler) recipe:
- 2 x Triangle detuned in unison.
- Detune untill the "beating" matches.

That's all. No (or fully opened) filter. The frequency of (detune) "beating" represents the difference in frequency between both (unison) oscillators.

Some reasons why results may vary in detail:
- Not all Triangles are the same.
- Even fully open filters with no resonance may change spectrum (e.g. due to phase changes and/or non-linearities).
- There's often postprocessing stuff like EQ, Drive/Saturation etc that may add/change "character".

Another option: FM

Assuming it's 2 detuned triangles.

Using Dexed (or any FM synth)

- you need 2 x 2 operator stacks (to emulate detuned 2 triangle oscillators), e.g. use Algorithm 1.
- ratio 1:2 (generating odd sideband frequencies only, since triangles contain only odd harmonics/partials)
- carrier levels at 100% (OP1 and OP3 at 99)
- modulator levels at some 65% (OP2 and OP4 around 65), the modulation amount is fairly low, so not to many high frequencies are generated, since we have no filter in FM.
- detune stack #2 just a little, e.g. 1.01/1.02 for OP3 and 2.03/2.04 for OP4.
- you can add some feedback (on OP2 in Algo 1) to add some buzz.

Another option: Filtered Squares (to effectively create Triangles).

- Just take 2 squares / 50% pulses and do the detuned unison thing (see above).
- Close the filter so only the first few partials are heard.

Unison is preferred, since just detuning wil periodically phase out the root partial / low end (definitely not wanted here).

You preferably need "perfect" squares for this one. Many "square" oscillators are not true 50% +1/-1 pulse/block oscillators. Many "square" oscillator shapes are variants where the top & bottom of the waveshape is not flat. Many have saw like shapes/characteristics mixed in.

These "imperfect" square shapes tend to add some extra harmonics/buzz. Also PWM to some 49% pulse will add some extra harmonics buzz. maybe you could tkae advantage of that to add the desired buzz level.

Slope and resonace setting depend on the filter characteristics. Maybe a 24 dB/oct with no resonance, maybe a 12 dB/oct with a lot of resonance (which effectively steepens the slope). Make sure the root (first harmonic, lowest frequency) is not attenuated: you need that low end.

Non-linearities and/or phase shifting, common in filtertypes, can be further exploited to shape the low end and buzz levels (using frequency and resonance).

If your synth(s) offers Drive or Saturation: do experiment with those too. Some mixer/filter drive/saturation can really work well to shape the low end and crackle/buzz (especially for these "odd" partials Bass sounds).

Another great example of this technique is the Heiko Laux "Ornaments" Bass.....

I love the ominous character and ambience it creates...
