The Killer Wail is considerably warmer and more “musical” than conventional wahs. Each of the three modes offers a wider, smoother, and more even sweep.
HIGH: Moves the wah filter to the high range of the guitar, perfect for leads or funky staccato chords.
EXTENDED: Tunes the wah to cover the entire range of the guitar. In this mode, the filter is not so “peaky” and is a good choice with clean guitars when you want a smooth and wide sweep.
DEEP: Moves the filter down to accentuate the lower strings of the guitar.
Mode Selector Switch: Provides a variety of curves for greater flexibility — for bass as well as guitar.
Humbucking Inductor: Custom wound and potted inductor coil cancels noise and reduces
microphonics, while faithfully reproducing the saturation and harmonics of vintage wahs.
Bypass Switch: There’s an extra pole to remove the circuit load, which can muddy & weaken the signal.
