Tech 21 lists Killer Blue Wail Bass Wah for August 2025
August 1, 2025 · 1 sources
Tech 21 lists the Killer Blue Wail Bass Wah with an anticipated availability of August 2025 on the product's page1. The same page also carries a second line reading "Anticipated availability: April/May 2025," so the maker's stated timing is not consistent within the page1.
The pedal is a wah designed for bass. Tech 21 says it "preserves the original tonal integrity of vintage wahs and overcomes familiar shortcomings, such as excessive noise and unreliable mechanical parts," and that "Unlike guitar wahs, the Killer Blue Wail for bass keeps the low-end intact"1. The maker states the pedal uses light sensor technology rather than a potentiometer, so there are "no clunky pops, no irritating scratching sounds, and no pots to wear out"1.
According to Tech 21, the filter is not a simple band-pass or low-pass design: "It not only changes the frequency, it also changes the Q, which is the sharpness of the filter"1. The rocker is spring-loaded, returning to its resting/bypass position when the foot is removed and engaging automatically when pressed forward1. The housing is machined from solid billet aluminum1.
"The Killer Blue Wail Bass Wah preserves the original tonal integrity of vintage wahs and overcomes familiar shortcomings, such as excessive noise and unreliable mechanical parts."
