Introduced by VOX in 1967, the Wah-Wah pedal stemmed from the Midrange Boost feature of a VOX amp design and was initially marketed as a way to emulate Clyde McCoy's trumpet mute technique. However, an unintended but music-changing use with electric guitar turned the Wah pedal into a vital tool for renowned artists such as Jimi Hendrix and Eric Clapton, driving the creation of now-legendary performances and songs. From the 1960s to today, the Wah pedal has become an essential tool for guitarists.
