Old Blood Noise Endeavors · pedal
The Old Blood Noise Endeavors BL-44 Reverse is a real-time reverse delay in the brand's variable-clock BL series, constantly reading back what you play forward to create true reverse effects. Its defining control is a Clock slider governing the system clock, which sets delay time and overall quality: sliding from left to right takes the sound from short, high-fidelity reverse playback to drawn-out, distinctly lo-fi, eerie reverse repeats. It can produce simple reverse delays, octave-up or octave-down reverses, glitchy artifacts, long swells, and bouncy, fairy-like textures. Designed for an immediate, tactile experience, it encourages players to keep a thumb on the slider and experiment. Simple in control yet surprising in sound, it suits ambient, experimental, and post-rock players chasing evocative backwards textures.
