Give your Eurorack synth some juicy low end with this Sub-Oscillator.

I put together a circuit that adds a square wave sub-oscillator to your modular synth for some really beefy tones

This Sub Oscillator tracks an oscillator signal from a VCO and generates a square wave at -1 or -2 octaves below. Works best with sawtooth, triangle, Sinus waveforms or simple square waves.

There’s a pot that mixes between the 2 sub-octaves and if you set it to 50% it sounds just like the famous Roland SH-101 pulse sub-oscillator.

For this to work, you need to route the oscillator output of your synth into the sub-oscillator Input. Then you get the sub-oscillator signal at the output. Mix it back with the original through an audio input chanel to enjoy that juicy low end.

PCB and Panel are safe RoHs compliant (Lead Free).

Due to the Covid situation, some delay may occur.
