Behringer Dual-Phase

Behringer · pedal

The Behringer Dual-Phase (also known as the Bi-Phase) is an authentic analog dual-phaser pedal modeled after a classic 1970s dual phase shifter. The circuit uses 12 optocouplers for natural organic phasing character. Two independent sweep generators each have their own Rate and Shape controls, allowing two simultaneous phase sweep speeds and waveform characters that modulate the signal simultaneously for complex phase interactions. True bypass. 9V DC or battery. Designed to capture the intense and natural effect of vintage dual-phaser units that used multiple independent LFOs.

What stands out

  • “Two independent sweep generators each have their own Rate and Shape controls, allowing two simultaneous phase sweep speeds and waveform characters that modulate the signal simultaneously for complex phase interactions”

    — from the listing

  • “Tone: dual-sweep analog phasing using 12 optocouplers producing complex layered phase modulation from two independent LFOs with separate rate and shape controls; results in richer and more complex phase patterns than single-LFO phasers”

    — from the community notes

  • “Designed to capture the intense and natural effect of vintage dual-phaser units that used multiple independent LFOs”

    — from the listing

  • “True bypass”

    — from the listing

  • “the dual sweep generators produce beat-frequency-style phase interference patterns when running at different rates”

    — from the community notes

Trade-offs

  • “Limitations: dual-LFO phase interaction is inherently semi-unpredictable, requiring patience to find consistent repeatable tones”
