The SpringVerb is a classic analog Spring Reverb Driver with a few extras.
The input signal goes into a state variable filter that is capable of self-oscillation. Then the filtered signal goes to the reverb driver, into the tank and back to a Voltage Controlled Crossfader for a CV-able Wet/Dry. The switch under the filter select switch determins what goes into the “Dry” side of the Crossfader. It can either be pre or post filter.
There is a Voltage Controlled Feedback section as well as CV for the Cutoff Frequency and the Resonance of the filter section.
The Feedback does exactly what it says, it feeds the Post Tank signal back into the input section. It can go from very subtile to guitar and amp style feedback.
The Filter is very similiar to the SeM20, so the Resonance is agressive. The input can be overdriven a little, depending on what the input is. Unlike the SeM20 it doesn’t really clip, but just like the SeM20 when the input is low and the Resonace is high most of what comes out is Sine waves.
Outputs: Filtered, Reverb Only and Mix
Tank: The SpringVerb comes with a medium size 3 spring tank and is compatible with many others.
