WahWah

Wah-Wah pedals are effects pedals that are used to produce a sweeping, vowel-like sound by modulating the frequency content of the input signal. They are often used to create a “talking” or “singing” sound, and are commonly associated with funk and rock music.

Wha-wha pedals work by using a mechanical or electronic filter to change the frequency response of the input signal in a sweeping manner. They typically feature a foot-operated switch or rocker pedal that allows the user to control the sweep of the effect.

Some popular examples of wha-wha pedals include the Dunlop Cry Baby, the Vox V847, and the Morley Classic Wah.
