The Walrus Audio Fundamental Series Ambient Reverb delivers vast, lush reverb tones with simplicity and professional-grade sound quality. Designed for both newcomers and seasoned musicians, this pedal provides a streamlined control interface without compromising tonal integrity. Perfect for everything from early band practices to sold-out arena shows, the Fundamental Ambient adds a rich, immersive layer to your tone.

Crafted and assembled at Walrus Audio’s headquarters in Oklahoma City, this compact pedal offers three distinctive reverb algorithms, enabling you to create a wide range of atmospheric sounds—from deep, moody pads to textured, lo-fi effects.

Main Features

• Three Reverb Modes for versatile ambient textures:
  • Deep: Dark, cavernous reverb with an added low octave for murky sustain and moody atmospheres.
  • Lush: Breathable, expansive reverb with ultra-long decay, ideal for silky pads and immersive soundscapes.
  • Haze: Textured, vintage-style lo-fi reverb featuring distortion, sample rate reduction and a resonant bandpass filter.
• Three Faders for Intuitive Control:
  • Decay: Adjust the length of the reverb tail—from short to infinite.
  • Tone: Shapes the overall character of the reverb. On Deep and Lush modes, it controls a lowpass filter cutoff; on Haze, it adjusts the bandwidth of a resonant bandpass filter.
  • Mix: Balance between dry (clean) and wet (reverb) signal to suit your style.
• Slide Switch to seamlessly toggle between the three reverb algorithms.
• Trails Mode for smooth reverb fade outs after bypassing the effect, enhancing natural decay.
• Durable construction with professional reliability designed to withstand the rigours of live performance.
