Behringer WAHWAH Optical Wah Effects Pedal with Boost

Optical control delivers a wear-free wah sweep with zero scratchy-pot noise, while the built-in +15 dB boost kicks in via a dedicated switch for instant lead volume.

Overview

The Behringer WAHWAH is a high-performance wah effects pedal built around a precision optical control system. Unlike traditional potentiometer-based wahs, the optical mechanism eliminates mechanical wear, ensuring consistent performance and a long lifespan. The pedal features a spring-back mechanism that automatically returns to the heel-down position when you lift your foot, making it ideal for quick, expressive playing. Two adjustable controls—Q and frequency range—let you shape the wah character from subtle to aggressive, while the heel-down and toe-down frequencies can be fine-tuned to match your instrument and style.
