The OBNE BL-52 Phase Repeater is a difficult pedal to describe because it doesn’t fit conventional categories.
It is somewhere between a phaser, a delay, and a reverb. It produces repeats that are phased rather than simply echoed.
The result is an effect that sounds like a room constantly changing in size and material – clear and distinct one moment, diffuse and washed out the next.
The BL-52 is part of OBNE’s BL series. This is a family of clock-defined pedals where a single Clock slider controls the timing of the entire system. Change the Clock and you change everything – the delay time, the LFO speed, and the overall fidelity of the phase repetition all at once.
Fast Clock settings give clear, rapid repeats. Slow Clock settings give long, trailing, diffuse delays that blur into something more reverb-like. It’s four parameters in one control.
Controls
- Clock (slider): Controls the timing of the entire system simultaneously — delay time, LFO speed, and signal fidelity. Fast gives clear rapid repeats; slow gives long diffuse trailing delays.
- Feedback: Lengthens the decay of the phase repetition further.
- Mix: Blends the dry signal with the phase repetition effect.
- Volume: Controls the master output level.

FAQs
It’s an effect that has been designed OBNE. It produces repeats that are phased , not just echoed. The result sits between a phaser, a delay, and a reverb, sounding like a room constantly changing in size and acoustic character.
It controls the timing of the entire system. Fast Clock gives clear, rapid repeats. Slow Clock gives long, trailing, diffuse delays.
The BL-44 is a reverse delay — it reverses your signal and plays it back. The BL-52 is a phase repeater — it applies phaser-style modulation to the repetition timing. Both use the same clock-slider architecture but produce completely different effects.
Yes — soft-touch true bypass footswitch.

OBNE’s BL series is a family of compact pedals built around a single Clock slider that controls the entire effect simultaneously. Previous BL pedals include the BL-44 Reverse, BL-37 Reverb, and BL-82 Chorus. Each takes a different effect type and reinterprets it through the clock-slider architecture.
