Electro-Harmonix Wailer Wah Pro Pedal - Black

The Electro-Harmonix Wailer Wah Pro puts a distinctive spin on classic wah expression, combining smooth, vocal-like sweeps and cutting clarity with a rugged metal chassis built for demanding stage use. Drawing on decades of EHX wah innovation, the Wailer Wah Pro features a custom inductor-free bandpass filter circuit that delivers an expressive voice with enough bite to stand out in the mix. Its responsive sweep brings character and movement to clean tones while maintaining definition through high-gain distortion without unwanted howl or feedback. A traditional foot-operated treadle provides intuitive control over the effect, while true bypass preserves the direct signal when the pedal is disengaged. With a durable die-cast aluminum-alloy chassis and convenient 9V battery operation, the Wailer Wah Pro brings expressive EHX tone and dependable construction to a familiar format.

Custom Bandpass Circuit Delivers Smooth, Expressive Wah Tone

At the heart of the Wailer Wah Pro is a custom bandpass filter circuit developed by renowned EHX designer David Cockerell, delivering a wah response that balances smooth, vocal-like character with clear, cutting definition. The inductor-free design helps minimize unwanted feedback, allowing the pedal to retain clarity and responsiveness even with heavily distorted tones. From subtle, rhythmic sweeps to pronounced lead phrasing, the circuit responds naturally to changes in foot position, giving players precise control over the effect's shifting tonal emphasis. Its carefully voiced response provides enough bite to remain present in a dense mix without becoming harsh or overly aggressive.

Rugged Die-Cast Construction Supports Reliable Stage Performance

The Wailer Wah Pro upgrades the original Wailer Wah's lightweight plastic housing to a rugged die-cast aluminum-alloy chassis, providing greater durability for regular stage use. A traditional rack-and-pinion treadle mechanism offers smooth, familiar operation, allowing players to shape the wah sweep with precise foot movements. True bypass keeps the pedal out of the signal path when disengaged, while an included 9V battery provides immediate operation without an external power supply. An optional power adapter (sold separately) offers additional convenience for pedalboard setups. Combining expressive tonal control with durable construction and straightforward operation, the Wailer Wah Pro is equipped for rehearsals, recording sessions and live performance.
