When it comes to guitar effects, there are numerous options available to musicians looking to add some extra flair to their sound. Among these effects are wah, expression, and volume pedals, which are staples in many guitar players’ setups. However, these pedals can be a bit confusing to those who are new to the world of guitar effects, so it is important to understand what each of these pedals does, and how they can be used to enhance your playing.
What is a Wah Pedal?
A wah pedal is a type of effects pedal that is designed to change the tone of your guitar. It works by altering the frequency response of your guitar signal, which in turn affects the tone. The wah pedal is activated by rocking the pedal back and forth, and the resulting sound can range from a subtle, sweeping effect to a bold, exaggerated sound.
Wah pedals are commonly used in funk, rock, and jazz music, and have been a staple in the rigs of guitar legends such as Jimi Hendrix, Eric Clapton, and Eddie Van Halen. When used in conjunction with other effects pedals, such as distortion and reverb, wah pedals can add a unique and expressive dimension to your playing.
What is an Expression Pedal?
An expression pedal is a type of effects pedal that allows you to control the level of a particular effect while you are playing. Unlike other pedals, which are typically switched on and off, expression pedals allow you to smoothly adjust the level of an effect as you play.
Expression pedals are most commonly used with volume pedals, but they can also be used to control the levels of other effects such as wah, reverb, and even distortion. By having control over the level of an effect while playing, you can add another layer of expression to your performance and bring your sound to life.
What is a Volume Pedal?
A volume pedal is a type of effects pedal that allows you to control the overall volume of your guitar while you play. This is achieved by changing the level of your guitar signal, which in turn affects the volume.
Volume pedals are commonly used to control the volume of an entire rig, but they can also be used to control the volume of specific effects. For example, you can use a volume pedal to control the volume of a delay effect, allowing you to bring the delay in and out of your sound as desired.
In addition to being useful for controlling volume, volume pedals can also be used for expression. By using a volume pedal in conjunction with an expression pedal, you can control the level of an effect as you play, and bring your sound to life.
Wah vs. Expression vs. Volume Pedals: What’s the Difference?
While all three types of pedals – wah, expression, and volume – can be used to enhance your playing and add expression to your sound, each type of pedal serves a different purpose.
Wah pedals are designed to change the tone of your guitar by altering the frequency response of your guitar signal. Expression pedals allow you to control the level of an effect while playing, while volume pedals are used to control the overall volume of your guitar.
It is important to understand the difference between these pedals, as they can be used in different ways to achieve different results. For example, you may want to use a wah pedal to add a funky, expressive sound to your playing, while using a volume pedal to control the overall volume of your rig. On the other hand, you may use an expression pedal to control the level of a reverb effect, adding depth and dimension to your sound.
In addition to their different functions, wah, expression, and volume pedals also have different control options. Wah pedals typically have a rocker pedal that is used to activate the effect, while expression pedals have a continuous control dial or footswitch. Volume pedals, on the other hand, often have a continuous control dial that can be used to adjust the volume.
It is important to choose the right type of pedal for your specific needs, as each type of pedal will offer different results and benefits. For example, if you are looking for a way to add expression and control to your sound, an expression pedal may be the right choice for you. On the other hand, if you are looking to control the overall volume of your rig, a volume pedal may be the best option.
