Walrus Audio Fundamental Ambient — Three Atmospheric Reverbs in One Stompbox

The Walrus Audio Fundamental Ambient packs three distinct reverb algorithms, giving guitarists and synth players lush soundscapes without menu diving. Each mode — Deep, Lush, Haze — is voiced for a specific atmospheric character, so flipping the slide switch moves from murky low-octave wash to breathy long-tail shimmer to gritty lo-fi texture.

What Sets the Fundamental Ambient Apart

Haze combines distortion, sample rate reduction, and a resonant bandpass filter — a rare combination that delivers vintage AM-radio-style lo-fi textures without external pedals. Deep layers an added low octave underneath the reverb tail, producing cavernous sustain shaped by a synth-style lowpass cutoff.

Three-Slider Control Layout

Three slide faders and a three-way mode switch replace menus, letting players dial in a sound in seconds. Each slider re-maps its behavior per algorithm.

• Decay: controls reverb tail length — how long the wash sustains after the note stops
• Tone: shapes algorithm-specific filter response — lowpass cutoff on Deep/Lush, resonant bandpass width on Haze
• Mix: blends dry and wet signal — fully clean at the left, fully wet at the right

Buffered Bypass and Connectivity

Buffered bypass with analog dry-through keeps the unaffected signal path untouched by the DSP, preserving the original tone before the reverb layer is mixed in. Top-mounted jacks keep cable layout tidy.

• Bypass Type: Buffered Bypass with Analog Dry-Through — dry signal stays analog
• Inputs: 6.3 mm TS (mono) — single mono input, mono pedal
• Outputs: 6.3 mm TS (mono) — single mono output to amp or next pedal

Enclosure and Power Requirements

The diecast housing measures roughly 110 × 55 × 41 mm, fitting on crowded pedalboards. Power comes from a standard 9 VDC adapter, and an isolated supply is recommended to avoid ground-loop noise.

• Enclosure: 110 × 55 × 41 mm diecast — compact footprint
• Power: 9 VDC, 100 mA minimum — standard adapter input
• Battery Powered: No — adapter-only operation
