Behringer Revives Classic B-TRON III Envelope Filter Pedal
Behringer B-TRON III Envelope Filter! Get that iconic '70s funk sound with three filter types, versatile range and drive controls.
Behringer has announced the re-release of the B-TRON III Envelope Filter, a pedal that originally made its mark on the funk and soul music of the 1970s. This updated version aims to recapture the iconic "quack" and "vowel" sounds that defined the era, offering musicians a versatile tool for shaping their tone.
Behringer B-TRON III Envelope Filter Pedal
Hot on the heels of the Behringer Chorus Symphony, now they have announced a remake of the classic '70s envelope filter by Mutron.
The B-TRON III is an envelope filter, meaning it automatically sweeps through a range of frequencies based on the dynamics of the player's input. This creates the signature "wah" or "vowel" effect beloved by guitarists, bassists, and keyboard players alike.
The pedal boasts three selectable filter types: low-pass, band-pass, and high-pass. This allows users to tailor the effect, from deep, throaty tones to bright, sizzling highs.

A key feature of the original B-TRON III, and retained in this reissue, is the Range switch. This switch allows users to select between "Low" and "High" ranges, affecting the emphasis of vowel-like sounds versus overtones. Furthermore, the Drive switch offers "Up" and "Down" modes, providing access to both the traditional "wah" sweep and a more static, "cocked wah" or "wow" sound.
Updates
Behringer has solved the original pedal's awkward power supply requirements, and this modern remake can be run off a standard 9v battery or power supply. They have also made the circuit true bypass, so it won't mess with your tone when it is not engaged.
Behringer's reintroduction of the B-TRON III brings this classic effect back to the forefront, offering a cost-effective way for musicians to explore the sounds of the '70s and beyond. The pedal's versatile controls make it suitable for various genres, promising to add a touch of funk to any setup.

What is an envelope filter and how does it work?
An envelope filter automatically sweeps through a range of frequencies based on the dynamics of your playing input, creating signature vowel-like or wah sounds. The B-TRON III's three selectable filter types—low-pass, band-pass, and high-pass—let you shape everything from deep, throaty tones to bright, sizzling highs.
What are the key controls on the Behringer B-TRON III?
The pedal features three selectable filter types, a Range switch (Low/High) that affects vowel emphasis versus overtones, and a Drive switch with Up and Down modes for traditional wah sweep or static cocked-wah sounds. It includes true bypass and runs off a standard 9V battery or power supply.
How does the B-TRON III differ from the original 1970s model?
Behringer modernized the design with a standard 9V power supply (replacing awkward original power requirements) and added true bypass so the pedal won't color your tone when disengaged. The core filter sounds and controls remain faithful to the vintage original.
