It’s time to get funky because we’re bringing back a pedal that shaped ‘70s music! This is the Behringer B-TRON III ENVELOPE FILTER.

Quack
The B-TRON III is a vintage envelope filter that creates a “Wah” or “vowel” sound every time you play a note. It includes three filter types via the Mode switch that includes low-, band-, or high-pass settings for a nice quack or a nice high-frequency sizzle. It works great for bringing the funk with either guitar, bass or keyboards.

Wah? More Like Wow!
The Range switch on the B-TRON III can be toggled between low, so you can get more vowel-like sounds, or high to emphasize more overtones. And the Up and Down modes on the Drive switch can give you that traditional “Wah” sound or a cocked “Wow” sound.

Amazing Flexibility
Having the B-TRON III is like having a piece of music history at your feet. It runs on standard 9 V DC power which makes integrating into your setup a total breeze. Its rugged and reliable metal construction also gives the B-TRON III the ability to stand up to the rigors of the road and the heaviest of stomps.
