SALLEN KEY is our tribute of the legendary MS-20 filter.
We've tried our best to honor this unique and iconic filter.
It’s composed of a 2 Poles Low Pass and a 1 Pole High Pass.
Unlike the original we add a crossader allowing you to blend the Low Pass and High Pass filters to create complex filtering.
What make this filter special it is non linear feedback path.
This design avoid the filter to clipping when self-oscillating, but also give it is unique color.
We’ve choose to integrate LED’s instead of diodes. It not only slighlty change the color of the resonance but also give nice feeback information about the drive of the resonance path.
Since SALLEN KEY can self-oscillate it can be use as sound source. Tracking is accurate across 6 octaves.

To help you to choose projects that meet your solder skills we've create difficulty scale you can find it under the DIY infos section on each product page.
Before to choose you can also consult the ibom in File section to evaluate by yourself the difficulty.
Regarding SMD soldering the scale have 3 levels :
- Level 1 is recommended for beginners who would like to try SMD soldering.
- Level 2 is recommended to people who already have successfully build few SMD modules.
- Level 3 is recommended for people comfortable with SMD. It may contain small and/or tight components and, due to the density of components, designators may-be not present on silkscreen.
Regarding THT soldering the scale have 3 levels :
- Level 1 is recommended for beginners who would like to try THT soldering.
- Level 2 is recommended to people who already have successfully build few THT modules.
- Level 3 is recommended for people comfortable with THT job. It may contain small and/or tight components and, due to the density of components, designators may-be not present on silkscreen.
