Behringer releases the B-TRON III Envelope Filter – a Funky Auto-Wah
It's time to funk.
It’s time to get funky (again). The Behringer B-TRON III Envelope Filter brings the sounds of the 70s back to your pedalboard. The original Mu-Tron III auto-wah had a huge influence on funk. Artists like Stevie Wonder, Frank Zappa or Bootsy Collins heavily relied on the pedal.

While the original Musitronics Mu-Tron III was short-lived, it’s influence, both on musicians and pedal makers, has only grown since its release in 1972. Bass legends like Larry Graham or Boostie Collins made the Mu-Tron an essential part of their funk sound. Stevie Wonder used it on ‘Higher Ground’, recording his Hohner Clavinet through it. Legends like Frank Zappa, Jerry Garcia or Steve Vai were fans.
After Musitronics was sold, founder Mike Beigel went on to work for Electro Harmonix, heavily influencing their Q-Tron-Series. And in 2014, he founded his own company Mu-FX where the Mu-Tron IV is available. While it has been an open secret that Behringer is working on their version of the famous ‘quack’ pedal, today they are finally releasing the B-TRON III.

Thanks to the range switch, you can switch between low and high to create vocal-like sounds or more intense overtones, giving you additional sonic dimensions and more expressive possibilities. The pedal is not only suitable for guitars, but also for bass and keyboards, making it a versatile tool for different music styles. The housing is made of metal and the pedal requires only a 9V block battery to work.
Additional Features
Another highlight of the B-TRON III is the up and down modes of the drive switch. The traditional ‘wah’ setting allows you to create smooth, dynamic sounds, while the ‘wow’ setting adds intensity and character.

Feedback among early adopters of Behringer’s vintage-themed pedal line including a Klon clone, a uni-vibe, the Brassmaster Bass Fuzz, the Octavia Octave Fuzz, and the just released Chorus Symphony is been pretty positive so far. Many praise how close Behringer came sonically for some of these models at a fraction of the price of the sought-after originals. Let’s wait and see (and heat) if the the B-TRON III will bring the funk back.
