A [Comb Filter](https://en.wikipedia.org/wiki/Comb_filter) modulated with a LFO.

## Knobs

* **DELAY:** adjusts comb filter [delay](https://en.wikipedia.org/wiki/Delay_\(audio_effect\)). 
* **AMOUNT:** adjusts LFO amplitude. 
* **RATE:** adjusts LFO frequency. 
* **FEEDBACK;** adjusts comb filter [feedback](https://en.wikipedia.org/wiki/Feedback).
* **NOISE:** adjusts amount of white noise mixed into input signal.

{% hint style="info" %}
The LFO modulates comb filter delay, this LFO takes the form of a [sine wave](https://en.wikipedia.org/wiki/Sine_wave#/media/File:Waveforms.svg).
{% endhint %}

## Buttons

* **Invert:** currently does nothing (safe to ignore).
