Abyss Devices Saevitum Filter

The Saevitum from Abyss Devices isn't your typical, smooth filter—it's gnarly and has a lot of gain distortion. It’s comes calibrated with normal settings but you can use the back “level” trimmers to taste to make it unstable and weird overloading the opamp and overall circuit around the RGB Led. You can even use it without any input and it will do some weird noise using the resonance and feedback knobs. RGB LED is under the tube and reacts to the output signal. You can choose which color using front panel trimmers or at the back trimmer for overall RGB effect amount. The RGB color you choose will affect the sound in weird and unpredictable ways especialy if you put it them all at 100%, which is the whole point of this module; to get weird tube sounds that would be very hard to reproduce on other equipment or software. If you don’t like the chaotic behavior, the trimmers are there for this reason, it can be tamed and set to taste or even completely disabled.
