Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.49% — somewhat different

The Old Blood Noise Endeavors BL-37 Reverb is a variable-clock reverb in the brand's BL series, adding modulation at two points in the reverb trail to create a wandering, lush, ever-shifting ambience with a simplified control set. Its signature feature is the Clock slider, which moves the sound from a quick, bright, tile-bathroom echo to a dark, lo-fi, time-stretched reverb, giving immediate, tactile control over fidelity and character. The dual modulation keeps the tails moving and organic rather than static, making it well suited to ambient, shoegaze, and experimental playing where evolving texture matters more than a clean room sound. It rewards keeping a thumb on the slider to morph the reverb in real time, offering a distinctive, characterful take on modulated reverb.
The Walrus Audio Fundamental Ambient is an affordable atmospheric reverb in the brand's streamlined Fundamental series, using three center-detented sliders for mix, decay, and tone plus a switch selecting three ambient reverb algorithms. Deep is a dark ambient reverb with an added low octave, Lush is a luscious reverb ideal for huge, sustaining pads, and Haze is a textured, lo-fi reverb with distortion, sample-rate reduction, and a resonant bandpass tone control for experimental sounds. The tone slider's function changes per mode, controlling lowpass cutoff for Deep and Lush or the bandpass width for Haze. It spans low-key spaces to enormous cosmic washes, complementing a conventional reverb. It suits ambient, post-rock, and shoegaze players wanting affordable, high-quality atmospheric reverb and pad textures in a compact, easy-to-use pedal.
