Modulation
Jacuzza
A phaser and a flanger in one tub on one wandering LFO: round bubbles and rushing jets, in series or side by side, with the lows kept dry and Surge to open it all up.

Every control, as its hover label says it in the plugin.
| Control | What it does | Range | Default |
|---|---|---|---|
| Swirl | How fast the water moves, in cycles a second: the bubbles' and the jets' sweep together. | 0.05 to 8 Hz | 0.45 Hz |
| Bubbles | The phaser: round notches rising and falling through the sound, wider and more resonant as it turns. At 0 there are none. | 0 to 100 % | 55 % |
| Churn | How far the water wanders: at 0 a steady, even sweep; turned up, each swing a different height and lean, never quite repeating. | 0 to 100 % | 40 % |
| Jets | The flanger: a rushing comb, deeper and with more feedback as it turns. At 0 there are none. | 0 to 100 % | 45 % |
| Temp | The warmth of the feedback in both the bubbles and the jets: low is bright and metallic, high dark and warm. | 0 to 1 | 0.6 |
| Flow | Series runs the bubbles into the jets, dense and stacked; Split runs them side by side, each heard on its own. | Series, Split | Series |
| Surge | Hold it to open the tub up: the swirl speeds up and the jets deepen, rising over a second or so and settling back when let go. | 0 to 1 | 0 |
| Mix | How much of the tub you hear against the dry signal: at 50% the notches are deepest, at 0 the input passes untouched. The lows stay dry throughout. | 0 to 100 % | 50 % |
| Surge Gate | Holds Surge while the cable is above half, as holding the button does; a stereo cable surges each side on its own. | 0 to 1 | 0 |
The pedal as the plugin draws it: each of its looks.




What goes in and what comes out.

- InIn
The signal into the tub, each side through its own phaser and flanger.
- OutOut
The signal through the tub, in stereo.
- LFOOut
The water's motion itself, each side's sweep from -1 to 1, the right a quarter cycle on from the left: patch it to move anything with the tub.
- WetOut
The tub alone, fully wet, whatever Mix says: the swept band above the lows, which stay dry and stay out of it.
