TECH 21 KILLER WAIL V2 WAH PEDAL

Killer Wail Wah Pedal
The Killer Wails preserve the original tonal integrity of vintage wahs and overcome familiar shortcomings, such as excessive noise and unreliable mechanical parts. Utilizing light sensor technology, there are no clunky pops, no irritating scratching sounds, and no pots to wear out. Machined from solid billet aluminum, the heavy duty housing will provide long life —on and off the road. Rather than utilizing simple band-pass or low-pass filters, the Killer Wails faithful emulation use a specially-designed filter. It not only changes the frequency, it also changes the Q, which is the sharpness of the filter.
