The Walrus Audio Fable Granular Soundscape Generator is a granular delay pedal that takes your signal, chops it into tiny samples called grains, and plays those grains back in ways a conventional delay cannot: backwards, at half or double speed, from multiple points at once, or at randomized pitches. Walrus Audio describes the results as "soundscapes ranging from smooth, flowing ambience; to bizarre, organic reverberance; to chaotic, glitchy swarms"1.
Inside, two DSP chips run two separate effects in series, and the output feeds back through both chips before reaching the output, a design Walrus calls a dual feedback path1. Pedal of the Day described the Fable as picking up where the Lore Reverse Soundscape Generator left off2.
The original Fable is discontinued and no longer available, per Walrus Audio's product page1. Blemished units were listed at $254.99, with flaws described as cosmetic only, such as scratches or dents in the finish3.
What granular delay does to your sound
Granular delay works by sampling short slices of your playing, called grains, and playing them back from a buffer. Because each grain can be reversed, pitch-shifted or scattered, the effect moves beyond repeats into textures: reversed swells that bloom behind your notes, octave-shifted clouds, or stuttering glitch when the grains get small. The Fable's five programs are, in Walrus Audio's words, "five granular delay programs centered around sample and chop algorithms"1.
The dual feedback path is what sets the circuit apart from a standard digital delay. Your signal runs through two separate effects in series, each with its own feedback control, and the looped signal passes back through both DSP chips before the output1. Gearnews described the same topology: "the signal is run through two separate effects in series"4.
The five programs
| Program | Signal path | What happens to the grains |
|---|---|---|
| 1 | Reverse Delay into Reverse Granular | Sampled grains are played backwards; grain size adjusts from long, smooth reversed transients to stuttering reverse glitch1 |
| 2 | Forward Delay into Octave Up Granular | Sampled grains are played at double speed1 |
| 3 | Analog-Style Delay into Octave Down Granular | A warm, dark analog-style delay feeds grains played back at half speed1 |
| 4 | Multi-Tap Granular into Multi-Tap Granular (Grain-Verb) | Two multi-tap granular algorithms in series; multiple samples play back from each granular buffer simultaneously3 |
| 5 | Forward Delay into Randomized Pitch Granular | Each grain plays back at a randomly selected speed and direction3 |
Program 4 is the deepest of the set. With two multi-tap granular algorithms running in series, multiple samples are played back from each granular buffer at the same time, and the Time knob controls time-stretching of both algorithms, changing both the length and the tonal character of the granular effect3. In Program 5, the X knob controls the rate of the randomized pitch modulation, letting you dial in how wild the pitch scatter gets3.
The controls
The Fable's knob set maps onto its two-stage architecture. The Feedback and Regen knobs each independently control one of the two series effects in the dual feedback path, so you can push repeats in the first stage, the second, or both1. Time sets the delay length, and in Program 4 it also stretches both granular algorithms3. The X knob changes function by program; in Program 5 it sets the rate of randomized pitch modulation3.
Tap tempo is available and has its own dedicated footswitch, so you can lock delay times to your tempo on the fly4.
Power and practicalities
The Fable draws 300mA minimum at 9V DC, center negative1. That is well beyond what a battery or a small daisy-chain output can supply, so plan on an isolated power supply with a high-current output.
Other practical details:
- Top-mounted input and output jacks, which help tight pedalboards4
- Die-cast enclosure measuring 3.62" x 4.79" x 2.25" including knobs1
- Gray enclosure with brown, tan, orange and dark gray ink, with art by David Hüttner1
- Covered by Walrus Audio's limited lifetime warranty1
Where it came from and what it costs
The Fable arrived in 2023 as a follow-up to the Lore, picking up where the Lore Reverse Soundscape Generator left off2. Gearnews covered the launch and listed it at $273.00 / £248.00 / 285.00€ at Thomann at the time4. Walrus Audio's later listing put the pedal at $299.99, with blemished units at $254.993.
For players comparing Walrus delays, the Fable sits at the experimental end of the range, focused on granular texture rather than the straightforward repeats of pedals like the ARP-87 or the Bellwether, and it shares its soundscape-minded character with the Lore rather than the high-fidelity Mako D12.

Questions
Is the Walrus Fable true bypass?
No. The Fable uses buffered bypass, not true bypass. That means a buffer circuit stays in the signal path when the pedal is off, which keeps your signal strength up over long cable runs but is not the same as a hard-wire true bypass switch.
Is the original Walrus Fable discontinued?
Yes. Walrus Audio's product page states the original Fable Granular Soundscape Generator is discontinued and no longer available. Blemished units were offered at $254.99, described as cosmetic flaws only such as scratches or dents in the finish.
What is the difference between the Walrus Lore and Fable?
The Fable picks up where the Lore Reverse Soundscape Generator left off, according to Pedal of the Day. The Lore is built around reverse soundscape effects, while the Fable is a granular delay with five programs centered on sample and chop algorithms, including reverse, octave up, octave down, multi-tap and randomized pitch granular effects.
Does the Walrus Fable have tap tempo?
Yes. Tap tempo is available and has its own dedicated footswitch, so you can set delay times in time with your music without bending down to adjust the Time knob.
