This analog flanger harnesses authentic bucket-brigade device (BBD) circuitry to deliver the sweeping, metallic modulation that defined 1970s rock and funk recordings. The Behringer B-Flanger builds on that vintage topology with an integrated optical foot pedal, allowing real-time manual control over the sweep rate, toggled via a dedicated footswitch, so guitarists can ride the effect during performance without touching a knob. True bypass switching ensures zero signal degradation when the pedal is disengaged, preserving clean tone integrity across the entire signal chain. The control layout offers comprehensive shaping of the flange character: oscillator speed ranges from slow, sweeping movements to rapid vibrato-like modulation, while the feedback control adds resonant peaks that push into metallic, vocal-like tones at higher settings. The optical foot pedal responds to pressure in real time, giving direct tactile control over the modulation sweep independent of the LFO rate. Housing construction uses durable metal with vintage-inspired cosmetics, and the pedal requires the optional Behringer PSU-SB DC power supply for operation. The all-analog signal path maintains the harmonic richness and sonic warmth associated with classic BBD flangers from the golden era of modulation effects.
