Behringer B-Tron III Auto Wah Envelope Filter

Funk legends know the secret weapon behind those iconic '70s grooves, and now you can harness that same legendary auto-wah magic with the B-TRON III Envelope Filter. This vintage-inspired pedal recreates the expressive "wah" and vowel-like tones that defined an era, responding dynamically to your playing style across guitar, bass, and keyboards. Built around an all-analogue optical circuit, the B-TRON III provides the natural, responsive feel that made envelope filters essential to the funk sound.

Three selectable filter modes give you complete tonal control�choose low-pass for deep, quacky funk textures, band-pass for classic auto-wah effects, or high-pass for sizzling treble emphasis. The Range switch adds another layer of versatility, letting you focus on vowel-like sounds in the low setting or bring out extra harmonics when switched high. Meanwhile, the Drive switch toggles between Up and Down modes, creating everything from traditional auto-wah sweeps to more vocal-like "wow" effects.

Built to withstand the rigours of professional use, this pedal features a rugged metal chassis and runs on standard 9V DC power for easy integration into any rig. The B-TRON III stands as a faithful recreation of vintage envelope filter magic, ready to inject serious groove into your sound palette.
