Old Blood Noise Endeavors · pedal
The Old Blood Noise Endeavors BL-52 Phase Repeater is a variable-clock effector in the brand's BL series that lives between phaser and reverb, sounding like a room constantly changing in size and materials. It alternates between clear and diffuse repeats, undulating beneath the player for an evolving, dimensional texture that is neither strictly modulation nor strictly reverb. Its signature Clock slider lets the sound move quickly and with fidelity or slowly and darkly, shaping how the phasing and repeats degrade and stretch. The result is an atmospheric, morphing ambience suited to ambient, shoegaze, and experimental players who want unusual spatial textures rather than conventional effects. Tactile and immediate, it rewards keeping a thumb on the slider to morph the space in real time.
What stands out
“It is used for ambient, shoegaze, and experimental textures, sitting in the chain as an atmospheric effect into clean amps, with the Clock slider moving it from quick, high-fidelity motion to slow, dark, degraded swells”
