History

"Vox's entry into the Wah-Wah pedal business came
about thanks to Brad Plunkett, a twenty five year old
engineer at Thomas Organ."

Around '66 Plunkett was working on a circuit to
replace the 3-position MRB (Mid Range Boost) or
voicing switch, with a less expensive potentiometer.

A fellow engineer, Les Kushner, suggested an
oscillator design which Plunkett then modified and
built.

To test the idea, a guitar was plugged in and, as
Plunkett describes
"all of a sudden people came running in to see what
was making this sound-they just freaked out on it."

After first considering a tremolo-arm method of
actuating the control, a volume pedal was quickly
reworked with the wah-wah circuitry.

Apparently Vox management saw lots of potential in
this new gizmo
............

By the early '80s only Thomas Organ, Morley, and a few
other companies manufactured wah pedals."
