The Effluence Spring Reverb is a reverb pedal from Poison Noises, released in November 2022. Pedal of the Day, which reviewed it on 4 November 2022, described it as a spring reverb that emulates everything from a small reverb tank to a massive ambient cathedral, all in a compact and extremely affordable pedal1.
The controls: six knobs
The Effluence carries six knobs, and Poison Noises gives each one its own name rather than the usual label. The names map to familiar reverb functions1:
For a player new to reverb controls, the pairs work like this: Dwell (Emanate) governs how hard the spring circuit is driven, while Decay (Project) sets how long the tail rings out. Size (Flow) sets how large the space sounds, Brightness (Spirit) and Fullness (Body) shape its tone, and Mix (Transcend) blends the effect against your dry signal1.
How it sounds
Poison Noises built the Effluence around two reverb engines, one flowing into another, together with a transparent EQ. Pedal of the Day summed up the range this gives1:
"With a transparent EQ, and one reverb flowing into another, there is no end to the variety of echoes you can leave behind."
The same review described the pedal's span as running "from simple tone-enhancing settings to full-on, blown out vintage reverb that lingers in your ears forever"1. In practical terms, that means the Effluence covers both subtle spring reverb that adds a little air to a clean tone and the saturated, dripping character of a vintage tank pushed hard, with the Dwell and Decay knobs setting where you land between the two1.

Questions
What does the transparent EQ do on the Effluence?
The Effluence carries a transparent EQ, meaning the reverb section is voiced so it does not color the tone of your dry signal. Pedal of the Day paired this with the pedal's cascaded reverb design, where one reverb flows into another, and noted that this combination gives the player a wide range of spring reverb textures, from small tank sounds to large ambient spaces, without the pedal imposing its own EQ character on the sound.
What do the Transcend, Flow and Body knob names control?
Poison Noises gives the Effluence's six knobs its own names. Transcend is the Mix control, blending the wet reverb with your dry signal. Flow is the Size control, setting how large the reverb space sounds. Body is the Fullness control, shaping the weight of the effect. The remaining knobs are Spirit for Brightness, Project for Decay and Emanate for Dwell.
What is the difference between Dwell and Decay on this pedal?
On the Effluence, Dwell is the Emanate knob and Decay is the Project knob. Dwell governs how hard the reverb circuit is driven, which affects the intensity and character of the spring effect, while Decay sets how long the reverb tail rings out. Used together they take the pedal from a small reverb tank emulation up to a massive ambient cathedral sound.
Is the Effluence a compact pedal?
Yes. Pedal of the Day described the Effluence as a compact pedal in its November 2022 review, noting that Poison Noises packed six controls, a transparent EQ and a cascaded two-reverb design into a small enclosure at an affordable price.
