Behringer HB01 Hellbabe Optical Wah Pedal

The Behringer HB01 Hellbabe Optical Wah Pedal replaces the traditional potentiometer found in most wah pedals with an optical sensor, meaning the pedal's sweep is detected without any mechanical contact. This design choice eliminates the scratchy, inconsistent response that plagues conventional wah pedals after extended use, keeping the Hellbabe's tone smooth and reliable over its lifespan. The pedal also features a unique spring-back mechanism that returns the treadle to the heel-down position when released — the spring tension is adjustable to suit your playing style, and the entire mechanism can be removed if you prefer a traditional free-rocking feel.

Where the Hellbabe really earns its keep is in its tone-shaping controls. The Range knob adjusts the heel-down starting frequency from 440 Hz down to 250 Hz, opening up the pedal to bass guitar use in addition to standard electric guitar. The Fine control sets the upper frequency limit up to 2.2 kHz, while the Q knob shapes the filter's resonance peak — from wide, mellow sweeps to tight, vocal-like cries. A built-in volume boost of up to +15 dB rounds out the feature set, giving you the option to push your amp harder when the wah is engaged. For guitarists and bassists who want deep control over their wah tone without a premium price tag, the Hellbabe delivers considerable flexibility.
