The Wailer Wah Pedal from Electro-Harmonix is a classic potentiometer-swept wah that delivers fluid wah tone in a responsive pedal at a budget-friendly price. Delivering the same great sound and tone of the award-winning Crying Tone Wah, the Wailer Wah offers a killer-sounding wah with cocked-wah tones, and utilizes a traditional rack-and-pinion style operating mechanism in a rugged, lightweight enclosure.
