Electro Harmonix Wailer Pro Guitar Effect
The Electro-Harmonix Wailer Wah Pro is an expressive wah-wah pedal built around a custom bandpass filter circuit that delivers sweet, smooth tones with just enough bite for both clean and high-gain playing. Housed in a rugged die-cast metal chassis with true-bypass switching, this road-ready stompbox is designed for players who want classic wah character without unwanted feedback or noise. The inductor-free design keeps the signal clean even when pushed with distortion.
- Inductor-free bandpass circuit designed by David Cockerell eliminates unwanted howl at high gain
- Die-cast metal chassis built for stage use, replacing the original Wailer Wah's plastic enclosure
- True-bypass switching preserves your dry tone when the effect is disengaged
- Runs on the included 9V battery or an optional 9.6VDC-200mA power supply
Wah-Wah Pedal with a Custom EHX Voice
The Wailer Wah Pro marks Electro-Harmonix's return to the wah pedal arena, continuing a funky lineage that began with the original Crying Tone and Queen Triggered Wah of the 1970s. Its custom bandpass filter creates a voice that's sweet and smooth with just enough bite, sounding musical on clean funk chords and high-gain leads alike.
Inductor-Free Circuit and Road-Ready Build
Designed by engineer David Cockerell, the inductor-free bandpass circuit eliminates the unwanted feedback and howl that traditional inductor-based wah circuits can produce at high gain. The chassis has been upgraded from plastic to sturdy die-cast metal for extended durability that feels natural underfoot.
Analog Circuit and True-Bypass Signal Path
True-bypass switching keeps the dry signal uncolored when the effect is off, and the analog circuit delivers immediate, musical response.
- Circuit: Analog — immediate, musical response with classic wah character
- True Bypass: Yes — uncolored dry signal when the effect is off
- Mono audio path through standard 6.3 mm input and output jacks
Flexible Power Options for Stage and Studio
The pedal ships ready to play with a 9V battery in the box.
- Battery Powered: Yes, 9V battery included — play straight from the box
- Current Draw: 6 mA — low draw for long battery life on stage
- Optional 9.6VDC-200mA center-negative power supply sold separately
Pedal Control and Road-Ready Construction
A single footswitch toggles the effect on and off, while the treadle pedal sweeps the wah filter for expressive work during performance.
- Controls: Footswitch, Pedal — engage the effect and sweep the filter with one foot
- Single footswitch for on/off operation
- Dimensions: 252 x 86 x 76 mm — compact footprint that fits standard pedalboards
Тype: Wah-Wah
Wah-Wah modulates the frequency spectrum of the sound, creating a distinctive vocal-like tone resembling the word "wah-wah". It is typically controlled by a foot pedal that smoothly alters the tonal range. It is used to add expression to solos, rhythm parts, or create dramatic effects, especially in rock, funk, and blues music.
True Bypass: Yes
It has a true bypass function, which ensures that when the effects are turned off, the signal passes directly through the unit without influence or degradation.
