There are two audio inputs with their level determined by a fader and a CV. Input 1 is routed to both the spring tank and the DRY input of the dry/wet mix. Input 2 is routed to the spring tank only.
Likewise there are two outputs: MIX emits the dry/wet mix while WET carries the effect signal only.
This configuration makes it possible to patch a feedback by connecting WET output with the IN 2. The voltage control of the input level allows for dynamic feedback fading.
Also it is possible to modulate the dry/wet mix i.e. the relationship between the original signal and the effect signal via a control voltage at the MIX CV socket.
A VU meter with seven LEDs visualizes the level and eventual saturation at the output.
The spring tank used is a 8BB2A1B type.
