The Electro-Harmonix Wailer Wah features a circuit that is very similar to the Crying Tone Wah but with a traditional rack and pinion style design.
The traditional style of the Electro-Harmonix Wailer, with movable pedal and a steady base, is much better suited to a pedalboard than the Crying Tone. The pedal is constructed in a light and cost-effective, but still very sturdy, high-impact plastic housing that’s designed to take years of abuse. The Wailer Wah Pedal is only about 1.5 pounds, making it less than half the weight of most other wah pedals. The Wailer Wah features a wide, even-sounding sweep, and the same expressive deep wah tones as the Crying Tone Wah.
Electro-Harmonix also ensured this pedal delivers an attractive cocked-wah tone when parked halfway through the treadle’s sweep. The wah also features true bypass switching, keeping your guitar tone as pure as possible by completely removing the electronics from your signal path when the pedal is disengaged. The pedal runs on a 9-volt battery or the optional EHX 9.6DC200mA power supply. The 9-volt battery can be changed using an easy-access battery compartment built into the unit.
