Killer Wail

WAH

The Tech 21 Killer Wail is a modern wah pedal that preserves the expressive sound of classic wahs while removing their mechanical limitations. It uses light-sensor technology instead of a traditional potentiometer, which eliminates noise, wear, and signal degradation. The pedal provides three selectable sweep ranges (High, Extended, and Deep) to shape the tonal response. Built from solid aluminum, it offers a compact, durable design suited for pedalboards. It can operate on battery or standard 9-volt DC power, delivering smooth, consistent wah performance.
