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 Mako Series R1 is a high-fidelity stereo reverb, the sequel to the acclaimed D1 delay, offering six reverb types with deep adjustment in a compact pedal. Dedicated Decay, Swell, and Mix knobs sit alongside a Tweak knob that accesses Rate, Depth, and Pre-Delay, a Tune knob for low and high frequency voicing, and an X parameter unique to each reverb, such as overdrive on Spring or room size on Hall. Modes include lush halls and rooms plus experimental voices like Refract, a glitchy texture over diffuse reverb, and Air, an aerated reverb with subtle shimmer. It excels at expansive stereo space and ambient exploration. It suits ambient, post-rock, and experimental players wanting a versatile, workstation-grade reverb with presets in a compact enclosure.
