Get ready to up your Wah game!
Tech 21 has announced the Killer Blue Wail Wah, a bass wah pedal designed to deliver classic vintage tone while solving the common issues of traditional wah pedals.

Vintage Tone, Modern Innovation
The Killer Blue Wail preserves the tonal integrity of classic wahs without the unwanted noise, scratchy pots, or mechanical failures. Thanks to light sensor technology, this pedal eliminates clunky pops and irritating scratches while providing a smooth, responsive sweep.
Built to Last
Crafted from solid billet aluminum, the Killer Blue Wail is built like a tank, ready to withstand the demands of touring and studio use alike. Its spring-loaded rocker returns to bypass mode when not engaged, making operation effortless and intuitive.
Designed for Bass
Unlike typical guitar wahs, the Killer Blue Wail ensures your low-end stays intact while providing a specially designed filter that adjusts both frequency and Q (the sharpness of the filter) dynamically. This means a more natural, musical response tailored for bass.
Specs:
- Dimensions: 3.375″ W x 8.0″ L x 1.75″ H
- Weight: 24 oz
- Power: 9V alkaline battery (not included)
Availability
The Killer Blue Wail Wah is set for release in April/May 2025. Stay tuned for updates and get ready to experience wah like never before!
