A wah-wah pedal (or just wah pedal) is a type of guitar effects pedal that alters the tone of the signal to create a distinctive effect, mimicking the human voice. The pedal sweeps the peak response of a filter up and down in frequency to create the sound (spectral glide), also known as “the wah effect.” The wah-wah effect originated in the 1920s, with trumpet or trombone players finding they could produce an expressive crying tone by moving a mute in the instrument’s bell. This was later simulated with electronics for the electric guitar, controlled by movement of the player’s foot on a rocking pedal connected to a potentiometer. Wah-wah effects are used when a guitarist is soloing, or creating a “wacka-wacka” funk styled rhythm.
A wah pedal is a type of pedal that alters the frequency of the electric guitar signal allowing the player to create a distinctive vocal-like sound by moving the pedal back and forth (known as “wah-ing”). This movement creates a filter effect that emphasizes one frequency range of the guitar signal while de-emphasizing others.
Let’s look at what that means and how it works.
What is a Wah Pedal?
A wah pedal is a type of effects pedal that alters the frequencies of an electric guitar signal, allowing for a shifting filter that the player can accurately control. The pedal is highly resonant and can bring a variety of sonic changes to the guitar’s overall form.
How Wah-Wah Pedals Work
The Basics: Understanding the Frequency Shifting Effect
At its core, a wah-wah pedal is a frequency shifter. It allows the player to create a distinctive onomatopoeic effect that mimics the sound of a human voice saying “wah.” This effect is achieved by engaging a bandpass filter that allows a specific range of frequencies to pass through while attenuating others. The result is a sweeping sound that can be bassy or trebly depending on the position of the pedal.
The Design: How the Pedal is Manipulated
The typical design of a wah-wah pedal features a shaft that is usually connected to a gear or toothed mechanism. When the player rocks the pedal back and forth, the gear rotates, changing the position of a potentiometer that controls the frequency response of the pedal. This linear control allows the player to manipulate the wah effect in real-time, creating a signature crying sound that is highly sought after by guitarists for soloing and adding texture to their playing.
The Benefits: Switchless Wahs and Wear Problems
While the physical connection between the pedal and the potentiometer is a common design feature, some manufacturers have opted to forgo this connection in favor of a switchless design. This allows the player to engage the wah effect without worrying about wear and eventual problems that can arise from the physical connection. Additionally, some switchless wahs offer a wider variety of frequency changes and can be easier to use for players who are new to the effect.
Enhancing Guitar Solos
One of the most common uses of a wah pedal is to add expression and dynamics to guitar solos. By using the pedal to sweep through the frequency range, guitarists can create a vocal-like quality to their playing that adds emotion and intensity to their performance. This technique is commonly used in genres such as jazz, blues, and rock, and was famously employed by artists like Jimi Hendrix, who wowed crowds with his use of the wah pedal.
Creating Envelope Filter Effects
Another use of the wah pedal is to create envelope filter effects. By adjusting the pedal’s control knob, guitarists can create a sweeping, filtering effect that alters the timbre of their guitar sound. This technique is commonly used in funk and soul music, and can be heard in songs like “Superstition” by Stevie Wonder.
Adding Texture to Rhythm Playing
While the wah pedal is usually associated with lead guitar playing, it can also be used to add texture to rhythm playing. By using the pedal to sweep through the frequency range, guitarists can create a pulsing, rhythmic effect that adds interest and depth to their playing. This technique is commonly used in genres like surf rock and was famously employed by Dick Dale.
Exploring New Sounds and Techniques
Finally, one of the most essential uses of the wah pedal is to explore new sounds and techniques. By experimenting with different pedal positions, sweep speeds, and control settings, guitarists can create a wide range of unique sounds and effects. This can be a fun and easy way to expand your playing and come up with new ideas for your music.
Overall, the wah pedal is an essential tool for any guitarist looking to add expression, dynamics, and texture to their playing. Whether you’re a beginner or a pro, there are plenty of tips and exercises to help you understand how the pedal works and how to use it effectively. So if you’re looking to take your guitar playing to the next level, be sure to check out the ultimate guide to wah pedals and start experimenting with this fun and versatile effect today!
Potential Parameter Controls For Wah Pedals
The Jimi Hendrix Connection: Vox and Fuzz Wahs
Jimi Hendrix is regarded as one of the greatest guitarists in rock music history. His iconic shows and images clearly show him using a wah pedal on a regular basis. He owned and used several wah pedals, including the Dallas Arbiter Face, which is now manufactured by Dunlop. The Vox and Fuzz Wahs were also central to his sound. The Vox Wah was the first pedal he obtained, and he used it to achieve the hypnotic lead parts and greater presence in his main riffs. The Fuzz Wah was an essential component in his practice to achieve memorable solos and achieve a mixed sound of extra higher octaves.
Frequency Sweeping and Altering
The main role of a wah pedal is to alter the frequency response of the guitar signal. The pedal offers a number of different frequency sweeps that produce similar but different sounds. The frequency sweep refers to the range of frequencies that the pedal affects. The highest resistance end of the sweep is when the pedal is closest to the ground, and the lowest resistance end is when the pedal is closest to the highest point. The frequency sweep can be altered by rotating the wiper, which is the conductive part of the pedal that moves along the resistive element.
Linear and Special Sweep Wahs
There are two types of wah pedals: linear and special sweep. The linear sweep wah is the most common type and has a consistent frequency sweep throughout the pedal’s range. The special sweep wah, on the other hand, offers a non-linear frequency sweep that is more vocal-like. The Vox and Fuzz Wahs are examples of special sweep wahs.
Feedback and Grounded Wahs
Wah pedals can also be used to create feedback by setting the pedal near the end of the frequency sweep. This can be achieved by grounding the pedal, which involves connecting the pedal to a conductive surface. This creates a loop between the guitar and the amp, which can produce a sustained sound.
EH Wahs and Other Ways to Wah
EH wahs are an exception to the linear and special sweep wahs. They offer a unique sound that is different from other wah pedals. Other ways to achieve a wah sound without a pedal include using pedalless equipment, software, or smart speakers. The Octavio pedal, which combines a fuzz and octave effect, is another way to achieve a wah-like sound.
In conclusion, a wah pedal is an essential component for guitarists looking to achieve a memorable sound. With the potential parameter controls available, including frequency sweeping and altering, linear and special sweep wahs, feedback and grounded wahs, and EH wahs, there are many ways to achieve a unique sound.

In this section, we’ll explore the different options available and help you decide where to place your wah pedal.
The Basics of Signal Chain Order
Before we dive into the specifics of wah pedal placement, let’s review the basics of signal chain order. The signal chain refers to the path that your guitar’s signal takes through your pedals and amplifier. The order in which you arrange your pedals can have a significant impact on the overall sound of your guitar rig.
Here are some general guidelines for pedal order:
- Start with any pedals that amplify or modify the guitar’s signal (e.g., distortion, overdrive, boost).
- Follow with modulation effects (e.g., chorus, flanger, phaser).
- Place time-based effects (e.g., delay, reverb) at the end of the chain.
Where to Place Your Wah Pedal
Now that we understand the basics of signal chain order, let’s talk about where to place your wah pedal. There are two main options:
1. Near the beginning of the signal chain: Placing the wah pedal near the beginning of the signal chain can help to amplify the effect and reduce noise. This setup is ideal if you want a more solid and consistent wah sound.
2. Later in the signal chain: Placing the wah pedal later in the signal chain can make it more difficult to control the effect, but it can also provide more advanced parameter controls. This setup is good if you want to use the wah pedal as a tone-shaping tool.
Here are some other things to keep in mind when deciding where to place your wah pedal:
- Access: Placing the wah pedal near the beginning of the signal chain makes it easier to access the pedal’s controls while playing.
- Interference: Placing the wah pedal later in the signal chain can be more susceptible to interference from other pedals, which can cause noise or unwanted effects.
- Security: If you’re using software or other advanced effects, placing the wah pedal later in the signal chain can help protect your personal information from being blocked or disabled by suspicious software.
- Reference: If you’re not sure where to place your wah pedal, try referencing other guitarists’ pedalboard setups or experimenting with different placements to find what works best for you.
In the world of effects pedals, the order of your signal chain can make a big difference in the overall sound of your guitar rig. When it comes to placing your wah pedal, there are two main options: near the beginning of the chain or later in the chain. Consider your personal preferences, the type of music you play, and the other pedals in your setup to determine the best placement for your wah pedal.

When buying a wah pedal for use with an instrument other than guitar, it’s important to understand the pedal’s capabilities and how to control it to obtain the desired effects. Unlike pedals for guitar, wah pedals for other instruments may not have the same positions or affect the same elements. However, they are capable of producing interesting sounds and greater expressiveness when used correctly.
Exploring Alternative Techniques to Use a Wah Pedal
1. Simply Use Your Foot
The most common way to use a wah pedal is to rock it back and forth with your foot while playing the guitar. However, there are other ways to manipulate the pedal to achieve different sounds. Here are some techniques to help you get the most out of your wah pedal:
2. Transfers and Tone Control
One way to use the wah pedal is to transfer the tone control from your guitar to your foot. This technique involves leaving the wah pedal in a fixed position and using your guitar’s tone knob to adjust the sound. By doing this, you can create a more subtle wah effect that is less pronounced than the traditional method.
3. The Matt Bellamy Technique
Matt Bellamy, the lead singer and guitarist of the band Muse, has a unique way of using the wah pedal. He places the pedal at the beginning of his signal path, before any other effects. This allows him to use the wah pedal to shape the sound of his guitar before it goes through any other effects, resulting in a more solid and consistent sound.
4. The Kirk Hammett Technique
Kirk Hammett, the lead guitarist of Metallica, uses the wah pedal in a similar way to Bellamy. However, he places the pedal at the end of his signal path, after all other effects. This allows him to use the wah pedal to add a final touch to his sound, giving it a unique and distinctive tone.
5. Let the Wah Pedal Marinate
Another technique to try is to let the wah pedal “marinate” in a fixed position. This involves finding a sweet spot on the pedal and leaving it there while you play. This can create a unique and interesting sound that is different from the traditional wah effect.
