In a previous post, we discussed some creative uses of the wah-wah creative uses of the wah-wah effect.
The first wah-wah pedal is attributed to Brad Plunkett in 1966, who worked at Warwick Electronics Inc., which owned Thomas Organ Company. Warwick Electronics acquired the Vox name due to the brand name’s popularity and association with the Beatles. Their subsidiary, Thomas Organ Company, needed a modified design for the Vox amplifier, which had a midrange boost, so that it would be less expensive to manufacture.
In a 2005 interview (M. Vdovin, “Artist Interview: Brad Plunkett,” Universal Audio WebZine, vol. 3, October 2005) Brad Plunkett said, I “came up with a circuit that would allow me to move this midrange boost … As it turned out, it sounded absolutely marvelous while you were moving it. It was okay when it was standing still, but the real effect was when you were moving it and getting a continuous change in harmonic content. We turned that on in the lab and played the guitar through it… I turned the potentiometer and he played a couple licks on the guitar, and we went crazy.
A couple of years later… somebody said to me one time, ‘You know Brad, I think that thing you invented changed music.’”
