Walrus Audio Fable MKII Granular Soundscape Generator Pedal - Grey

The Walrus Audio Fable MKII Granular Soundscape Generator  is a stereo ambient creation machine built around delay and micro-sampling granular processing. Built on Walrus Audio's high-fidelity MDSP digital platform, the Fable MKII features five streamlined modes that pair two distinct algorithms in series, running them through dual independent feedback paths. Rather than repeating predictable patterns, your signal continuously evolves into long reversed textures, bright double-speed cascades, pitch-scattered swarms, and glitchy reverberance. Complete with full stereo width control, LFO modulation, expression mapping, and 128 available presets, the Fable MKII transforms standard guitar signals into organic, storybook soundscapes.

Driven by an intuitive control scheme, the Fable MKII introduces the Tweak knob—a single-encoder solution that grants instant access to Width, Mod Rate, Mod Shape, Shift, and Ramp parameters. Musicians can trigger momentary pitch bends using the Dive / Rise tap-tempo switch, send 1/8" TRS MIDI clock and CC control, or assign any parameter to an external expression pedal. Powered by isolated 9VDC, the Fable MKII delivers studio-grade processing housed in a durable enclosure featuring evocative artwork by Niall Grant.

Key Features:

• Dual Feedback Architecture: Runs two separate effects in series with independent Feedback and Regen controls, continuously reshaping audio through separate feedback paths.
• 5 Streamlined Granular Modes:
  • Mode I (Reverse Delay into Reverse Granular): Smooth reversed transients or stuttering glitch textures.
  • Mode II (Forward Delay into Octave Up Granular): Bright, double-speed cascades and airy pitched swarms.
  • Mode III (Analog Delay into Octave Down Granular): Dark, slowed-down repeats for deep, thunderous ambiance.
  • Mode IV (Multi-Tap Granular / Grain-Verb): Dual multi-tap buffers creating dense, organic reverb clouds.
  • Mode V (Forward Delay into Randomized Pitch Granular): Randomized speeds, directions, and pitch modulation per grain.
• Tweak Knob Control: Single encoder lets you quickly cycle and set Width, Mod Rate (0.1 Hz to 5 Hz), Mod Shape (Sine, Square, Random), Shift (0.5x to 2x), and Ramp (50 ms to 5000 ms).
• Momentary Dive / Rise: Holding the tap tempo switch momentarily shifts pedal clock rate for dynamic pitch glides.
• Presets & Full MIDI: Save 3 onboard presets (plus live mode) or access up to 127 presets and full CC control via 1/8" TRS MIDI.
• MDSP Engine: Built on Walrus Audio’s proprietary high-fidelity digital processing platform.
• Selectable Bypass: Features switchable Trails (natural decay) and No Trails (abrupt cut) bypass modes.
