Fonitronik Ps3100 Triple Vactrol Resonator - Time Lapse Build
In our latest build we take on the Fonitronik Ps3100 Triple Vactrol Resonator – A clone of the lovely triple resonator from the rare 1977 Korg Ps3100 polyphonic modular.
What we have here is basically a module combining three bandpass filters (vactrol based filter core from the PS3100) with a simple resettable LFO and some clever CV and signal routing. The LFO is normalized to the common CV input, which is normalized to the 3 single CV inputs. the 3rd CV channel can be inverted.
The build itself was a timely one and it took great patience and a skillful hand to complete. As they stated in the description “Not for the beginner”, remained true. We don’t recommend this kit to anyone just getting started in the Eurorack DIY realm as it can easily be overwhelming and a simple soldering mistake can cause feelings of anxiety and let down.
Now, if you successfully complete the module as we did, the module itself can be a prize possession in your rack. The triple vactrols do exactly what they say they will do and resonate some of the warmest sounds from the 1970’s. Hence, another reason why this module is special. The warmth of the analog audio is something that is rare to find in today’s Eurorack systems.
If you are down for a challenge and are needing some much provided warmth in your rack, this might just be the perfect module for you!
