Building upon Walrus Audio’s modern-classic Slo reverb, the Sloer Stereo Ambient Reverb pedal takes the formula to a whole new realm of lush atmospheres and celestial soundscapes. Fans of the original will be happy to hear that the Sloer comes packed with the former’s stable of reverb algorithms and distinctive modulation waveshapes. You get a grand otal of five masterfully crafted reverb algorithms and five equally idiosyncratic modulation waveshapes, covering everything from sunny octave-up shimmer ’verb to trippy delay tap diffusion to ghostly waves of octave-down undulation. You also get a 3-way switch to set your stereo field, the ability to set your sample rate, and the Sweetwater-favorite “X” knob that unlocks eccentric per-algorithm effects. Complete with adjustable trails, dynamic momentary functions, and saveable presets, the Sloer is truly a masterclass in the art of echo-laden ambience.

Walrus Audio: The Sounds In Our Heads


Three classic Slo reverbs plus two all-new algorithms





In addition to supplying you with the same reverb algorithms found on the Slo, the Sloer introduces two all-new algorithms for five distinctive echo choices. Plus, the Sloer’s “X” control unlocks a unique per-algorithm parameter to further tweak your tone!





Dark: This setting injects a lower octave into your reverb’s trail for a moody, melancholy vibe perfect for crafting eerie dreamscapes. In Dark mode, the X knob allows you to dial in the strength of the octave-down signal that feeds the reverb.


Rise: Full of movement and lively energy, Rise is an auto-swell reverb with a mind of its own. Tweak the X knob in Rise mode to adjust how fast the reverb begins to swell after your strike a note.


Dream: If you’re after lush, pillowy pads, Dream is sure to impress. This setting sports a unique latching interaction with the Sustain switch, while the X knob dials in the depth of your reverb trail’s vibrato.


Rain: This mode offers an idiosyncratic delay tap diffusion that creates a storm of resounding echoes within your reverb tone, with the X control modifying the diffusion of the delay taps.


Light: Finally, Light mode gives you a sunny octave-up reverb for classic shimmering soundscapes. Twist the X mode with this algorithm selected to sweep from supple pad-like reverb to angelic shimmer-heavy ambience.


Packed with moody modulation





In essence, the Sloer is all about crafting lush and ghostly soundscapes. A seriously powerful modulation section plays a starring role in the formula, granting you five different waveshapes to choose to rend, twist, and warp your reverb trails. Hold down the bypass switch and turn the algorithm knob to set your waveshape.





Sine: Supremely smooth and even up/down pitch modulation.


Warp: A wild asymmetrical pitch-up modulation that captures the vibe of a warped record.


Sink: Asymmetrical pitch-down modulation, boasting a sound eerily close to a classic guitar vibrato unit.


Square: Symmetrical pitch up/down modulation for a stepped, almost rhythmic feel.


Random: This waveshape utilizes a sample/hold that picks random values.


A myriad of momentary effects and utility functions





Boasting a vast array of momentary functions and utility features, the Sloer is a veritable instrument unto itself. When testing this pedal out at Sweetwater, one of our favorite features was the dynamic Sustain switch ? a momentary (latching in Dream mode) reverb ramp that consistently cranks up your reverb up to the max setting, then cascades back down when released. Looking to add a touch of ambient vibe to a quick passage or melody amid a performance? Hold down the bypass switch when the pedal is disengaged to activate the Sloer’s current algorithm for as long as you have the switch depressed, then release for a smooth taper off that can be adjusted using the Decay knob.





Moreover, the Sloer also comes equipped with a trails mode, allowing you to choose whether your reverb naturally dies down or instantly disengages when you turn the pedal off. And fans of sweeping stereo effects will love the 3-position stereo width control that sets the scale of your stereo field. Lastly, the Sloer takes a note from the Slotva’s book by allowing you to save your favorite presets (accessed by holding down the bypass/sustain switches at once), in addition to a preset spillover function that allows trails when swapping from two presets stemming from the same algorithm.
