The Killer Wail v2 preserves the original tonal integrity of vintage wahs and overcomes 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 Wail v2’s faithful emulation uses a specially-designed filter. It not only changes the frequency, it also changes the Q, which is the sharpness of the filter.

Killer Wails are phantom operable via Fly Rig 5 v2 with a modification to the Fly Rigs. Details are available from Tech 21.
