The Electro-Harmonix Wailer Wah has the exact same thick and singing tones as the company's ground-breaking Crying Tone Wah but puts it in a convenient and familiar rack and pinion-style enclosure. The Wailer Wah is built with a durable polymer casing that will stand up to the rigors of the road, while removing some weight from your pedalboard. And the Electro-Harmonix Wailer Wah effects pedal is true bypass. This keeps your guitar's tone completely pure while the effect is disengaged. The Wailer Wah puts EHX's great wah tones in a familiar package.
