The Behringer B-TRON III Envelope Filter is a faithful recreation of the iconic auto-wah pedal that defined the funky sounds of the 1970s. Whether you play guitar, bass, or keyboards, this versatile pedal reacts dynamically to your playing, delivering rich, expressive “Wah” and vowel-like tones.

Key Features

  • Classic Auto-Wah Filtering – Recreates vintage envelope filter sounds with low-pass, band-pass, and high-pass modes, allowing for expressive funk tones and high-frequency sizzle.
  • Versatile Range & Drive Modes – Switch between low and high frequency emphasis, and choose Up or Down drive settings to achieve either traditional Wah or cocked “Wow” sounds.
  • Wide Dynamic Input & Gain Control – Handles instruments with a +30 dBu input range and offers up to +40 dB gain, making it suitable for both subtle filtering and bold tonal shaping.

Featuring three selectable filter types – low-pass, band-pass, and high-pass – the B-TRON III lets you dial in anything from a deep, funky quack to a sizzling high-end bite. The Range switch further tailors the sound, offering both low (for warm, vowel-like articulation) and high (for pronounced overtones) settings.

Additionally, the Drive switch provides Up and Down modes, letting you choose between a traditional sweeping Wah or a cocked “Wow” effect. Designed for powerful performance and tonal flexibility, the B-TRON III boasts an impressive gain range of +40 dB, ensuring a wide input dynamic range for professional use. Compact and robust, it runs on a standard 9V DC power supply and is built to handle the demands of the stage and studio alike.

Guitar Pedals

Guitar pedals are compact effects units that shape and enhance a guitar’s sound, sitting between the instrument and the amplifier. They include gain pedals like overdrive and distortion, modulation effects such as chorus and tremolo, time-based effects like delay and reverb, and essential utilities including tuners, compressors and loopers. Understanding basic things such as pedal type, signal order, power requirements and intended use helps players choose pedals that suit their style, setup and playing environment.

Envelope

Envelope effects respond dynamically to how hard or softly you play, shaping the sound based on the input signal rather than a fixed control. The effect opens and closes in real time, creating tonal changes that follow your picking or playing dynamics.

They are most commonly associated with envelope filters and auto-wah effects, producing expressive, vocal-like sweeps that react to touch and groove. Envelope effects are widely used in funk, jam, electronic, and experimental music, where rhythmic feel and player interaction are central to the sound.

Filter

Filter effects shape tone by allowing certain frequencies to pass through while reducing or removing others. By sweeping or adjusting the cutoff point, filters can dramatically change the character of a sound, from subtle tonal shaping to bold, expressive sweeps.

Filters are commonly used in pedals, synthesizers, and processors, often in the form of low-pass, high-pass, or band-pass designs. They are valued for their ability to create movement, focus, and texture, especially in funk, electronic, ambient, and experimental music.

Pedal

Pedals are the tools that let you shape, colour and transform your sound, from subtle tone enhancement to bold, creative effects. Whether you are adding grit, space, movement or control, a pedal becomes part of your playing rather than just an add-on. Exploring different pedals is about discovering what responds to your touch and helps your sound feel more like your own.

Vintage

Vintage describes gear that is inspired by, or originates from, an earlier era of guitar design and sound. Vintage-style pedals, guitars, and amplifiers focus on classic tones, simpler circuits, and traditional aesthetics, delivering warm, characterful sounds that are closely associated with early rock, blues, and classic recordings.
