Behringer has officially raised the bar for accessible vintage modulation with the release of the B-Flanger, a brand-new true analog Bucket-Brigade Device (BBD) pedal at a competitive price.

Designed to capture the swirling, vocal-like halos and aggressive jet-engine swooshes that defined the golden age of 1970s rock and funk, the B-Flanger merges authentic retro circuitry with modern, gig-ready reliability. Standing out in a crowded market of digital emulations, this pedal promises players the three-dimensional, warm modulation of vintage studio classics, paired with unparalleled real-time expression.

The Power of True Analog BBD Circuitry

At the core of the Behringer B-Flanger is a genuine analog bucket-brigade device (BBD) circuit.

While modern digital algorithms often struggle to replicate the organic imperfections of vintage gear, the B-Flanger delivers rich, musical movement with a warm top-end roll-off.

This all-analog approach delivers the metallic shimmer and thick, doubled-up textures that sit well in dense studio mixes and live band environments, flattering both crystal-clean chords and heavily overdriven solos.

A Rare Effect Reborn

This model is based on the rare original Mu-Tron Flanger pedal, which is hard to find and is from the 1970s era of effects pedals. Behringer has pretty much cloned the original circuit and design.

Unprecedented Live Expression: Integrated Optical Foot Pedal

While standard flangers rely exclusively on a low-frequency oscillator (LFO) to control the modulation sweep, the B-Flanger introduces a massive advantage for live performers: an integrated optical foot pedal.

By clicking the dedicated pedal footswitch, guitarists can instantly bypass the fixed LFO and take manual, physical control of the flange sweep in real time.

This optical expression system allows for hands-free, on-the-fly manipulation. Players can ride the sweep to match their playing dynamics, creating expressive, wah-like filter effects, dramatic build-ups during breakdowns, or customized rhythmic pulses that a static rate knob simply cannot provide.

Versatile Tone Sculpting

For players who prefer traditional LFO modulation, the pedal’s control panel offers surgical precision over the effect's character:

  • LFO Rate: Dial the speed from a glacially slow, spacious ambient wash all the way to a chaotic, vibrato-fast wobble.
  • Oscillator Sweep: Control the depth and width of the modulation, allowing for subtle chorus-like thickening or massive, dramatic swooshes.
  • Feedback Intensity: Push the resonance from smooth and subtle to an intense, almost-singing metallic peak that borders on self-oscillation.

Gig-Ready Build and True Bypass

Housed in a robust, retro-styled enclosure, the B-Flanger is built to withstand the rigors of regular gigging and rehearsal schedules.

Behringer has wisely outfitted the pedal with true bypass switching, ensuring zero tone coloration or signal degradation when the effect is disengaged—a crucial feature for players meticulously managing their pedalboard signal chain. The unit is powered by the optional Behringer PSU-SB DC power supply, making it an easy integration into modern pedalboard setups.

What makes the Behringer B-Flanger different from digital flanger pedals?

The B-Flanger uses genuine analog bucket-brigade device (BBD) circuitry instead of digital algorithms, delivering organic, warm modulation with metallic shimmer and thick textures. This all-analog approach replicates the imperfections and richness of 1970s vintage gear, which digital emulations struggle to achieve.

Can you control the flange sweep in real time?

Yes. The B-Flanger includes an integrated optical foot pedal that lets you manually manipulate the flange sweep in real time, bypassing the LFO. This allows hands-free, on-the-fly control for expressive wah-like effects and dynamic build-ups that a fixed rate knob cannot provide.

What are the main controls on the B-Flanger?

The pedal features LFO Rate (speed control), Oscillator Sweep (modulation depth and width), Feedback Intensity (resonance from subtle to self-oscillation), and a dedicated footswitch to toggle between LFO and optical foot pedal control modes.

Is the B-Flanger based on a specific classic pedal?

Yes, it's a clone of the rare 1970s Mu-Tron Flanger. Behringer recreated the original circuit and design, making the sought-after vintage tone accessible at a fraction of the original's cost and rarity.
