who invented the wah wah pedal?

Answer 1

History
The earliest version, which sweeps the peak response of a filter up and down in frequency to create the sound, was first heard in 1945 on a pedal steel guitar created by Leo Fender and in the early 1960s on Vox amplifiers (under the name Wah-Wah) and Thomas electronic organs (as the Crybaby). B.J. Plunkett et al, applied for patent protection Feb. 24, 1967 and were granted US Patent 3,530,224 Sept. 22, 1970. The variation in the peak response frequency of the filter resembles the change in formant frequency in the human vocal tract when saying the word "wah", making the wah-wah pedal a crude form of speech synthesizer. As the wah wah pedal is rocked back and forth, bass is taken off the guitar's tone, and treble is put on. The "wah wah" effect thus does not affect the guitar's volume.

There are two types of wah pedals: one that lets the player control the effect via a foot pedal, and one that adjusts the effect automatically according to the amplitude of the signal from the guitar (auto-wah, or envelope-followed filter).


[edit] Guitarists
The first recorded use of a wah-wah pedal was by Chet Atkins, who used a pedal that he had built himself on the 1961 recording "Boo Boo Stick Beat".

Session guitarist Big Jim Sullivan used a wah-wah pedal on the 1961 record "Sweet Little Sixteen" by Michael Cox. The first UK hit using a wah-wah pedal was on the 1964's " The Crying Game" by Dave Berry - again by Sullivan.

Frank Zappa extensively used a Wah-wah pedal but did not always use it in the conventional way of rocking it back and forth.
