Walrus Audio Fundamental Series Reverb

The Walrus Audio Fundamental Reverb delivers essential ambient tones in a streamlined, user-friendly format, perfect for players of all experience levels. With three classic reverb algorithms—Hall, Spring, and Plate—it covers a wide range of spatial textures, from spacious and atmospheric to focused and vintage-inspired. Whether you're adding subtle depth or immersive ambient trails, the Fundamental Reverb offers reliable, expressive performance in a compact design.

Three intuitive sliders let you control Decay, Tone, and Mix, allowing you to fine-tune the length, brightness, and blend of your reverb. The mode switch toggles between Hall for a wide, diffused feel, Spring for classic amp-style bounce, and Plate for rich, smooth reflections. Trails mode is enabled by default for natural decay, but can be turned off for abrupt cutoff, giving you full control over how your reverbs respond. Designed and assembled in Oklahoma, the Fundamental Reverb brings professional-quality ambience to any pedalboard with ease.
