Wah-Wah Pedal, my favourite ones

Hi Everyone,
the Wah-Wah Pedal, in this post we talk about another iconic pedal. The birth of this effect is entirely random. The first pedal was presented to the public in 1966 by the producer was Warwick Electronics Inc. / Thomas Organ Company. This pedal was named Clyde McCoy in honor of the trumpeter who used to vary the phrasing of his instrument with a Harmon Mute in 1920. Legend says that in 1965 Brad Plunkett was paid to disassemble Vox AC-100 and find out if there was a way to make it at a lower cost.

The Genesis

The amplifier had a switch to push the mid frequencies and Plunkett realized that the key could be replaced by a potentiometer. After drawing a circuit that varied the frequency, he asked a friend to connect the guitar to the amplifier and while he was playing, Brad moved the potentiometer. Thus, Wah-Wah was born. Since the guitarists have their hands slightly occupied, he thought of turning an organ pedal into a pedal to control the potentiometer of his invention.

What is the Wah-Wah Pedal

The effect of the Wah-Wah Pedal is a characteristic sound produced by a narrow band filter that accentuates a frequency band that varies over time. One could say that you simulate vaguely similar to a meow or a cry. Precisely for this reason it can also be called baby cry.  Technically, the Wah-Wah Pedal is a frequency filter in which the central frequency range is moved by a potentiometer, controlled by the pedal. The potentiometer is set to close the frequency, setting the range on the low frequencies and cutting the others. When the pedal is towards the heel (pedal up), a very closed and unclear sound is produced. In peak position (pedal stepped) mid-highs are opened generating a much sharper and more incisive sound. Moving the pedal back and forth generates the Wah-Wah effect.

Who made him famous and who uses it nowadays

Wah-Wah Pedal can be found in all kinds of music and recently also in Metal. This pedal is one of the few traditional musical effects that have not been changed by digital versions or sound processing software. Virtually every self-respecting guitarist has a Wah-Wah pedal on his pedal deck. The first to bring it to success were Hendrix and Clapton. It is easy to imagine how many artists and ordinary people have inspired. Famous pedaling artists include Zakk Wylde, Jimi Page, Steve Vai and Tom Morello.


Before proceeding with my reviews I wanted to spend few words on this online downloadable tutorial that includes all the various effects that i’ve already indtruced for the Distortion Pedal review. This tutorial is well-structured giving a general overview on all the effects. I consider it a bit like a bible for whom wants to start venturing into the fantastic world of guitar Pedal.

Volume Boost for an additional gain up to + 15dB. finally the Auto-Return function that allows you to automatically activate the effect by resting your foot on the pedal. All this in addition to an impressive and versatile wah sound.
