Types of Effects Processors
Distortion Effects
Overdrive
Overdrive is a type of distortion effect that occurs when an amplifier is pushed beyond its limits, causing the signal to become distorted. This effect is often used to add warmth and sustain to a guitar signal. Overdrive pedals are designed to recreate this effect, allowing guitarists to achieve a similar sound without having to crank their amplifier to its maximum volume.
Fuzz
Fuzz is another type of distortion effect that is created by intentionally distorting the signal with a high-gain amplifier or a specialized effect pedal. This effect is often used to create a harsh, aggressive sound that is characteristic of rock and metal music. Fuzz pedals come in many different varieties, each with its own unique sound and characteristics.
Distortion
Distortion is a broad category of effects that includes both overdrive and fuzz, as well as other types of distortion such as modulation and multi-band distortion. Distortion effects are designed to add a gritty, aggressive sound to a signal, often by introducing harmonic overtones and saturation. Distortion pedals are versatile and can be used with a wide range of instruments and musical genres.
Overall, distortion effects are an essential part of many different types of music, from rock and metal to blues and jazz. Whether you’re looking to add some grit to your guitar tone or create a unique sound for your synthesizer, there is a distortion effect that is right for you. With so many different types of distortion effects available, it’s easy to find one that fits your style and sound.
Modulation Effects
Modulation effects are a category of audio effects that create a dynamic and changing sound by modulating one or more parameters of the audio signal. These effects are used to add depth, movement, and interest to a sound. The four main types of modulation effects are chorus, flanger, phaser, and tremolo.
Chorus
A chorus effect is created by duplicating the original audio signal and slightly detuning each copy. This creates a thicker, richer sound, similar to a group of singers singing the same phrase in unison. Chorus effects can be used to add depth and richness to a sound, or to create a more ethereal, otherworldly effect.
Flanger
A flanger effect is created by creating a slight delay in the signal and then subtracting it from the original signal. This creates a “whooshing” sound that is often used to create a sense of movement or depth. Flanger effects can be used to add interest and movement to a sound, or to create a more psychedelic, otherworldly effect.
Phaser
A phaser effect is created by filtering the audio signal through a series of all-pass filters, which are filters that have no effect on the audio signal. This creates a “swooshing” sound that is often used to create a sense of movement or depth. Phaser effects can be used to add interest and movement to a sound, or to create a more psychedelic, otherworldly effect.
Tremolo
A tremolo effect is created by rapidly increasing and decreasing the volume of the audio signal. This creates a “wobbling” sound that is often used to create a sense of movement or instability. Tremolo effects can be used to add interest and movement to a sound, or to create a more dramatic, dynamic effect.
Filter Effects
Filter effects are a type of effects processor that works by altering the frequency content of an audio signal. They are used to enhance or remove certain frequencies from the signal, creating a wide range of tonal changes. In this section, we will discuss the three main types of filter effects: wah-wah, envelope filter, and equalizer.
Wah-wah
Wah-wah is a type of filter effect that is created by using a bandpass filter to selectively remove certain frequencies from the signal. The effect is controlled by an envelope follower, which tracks the volume of the input signal and opens or closes the filter based on the level of the input. This creates a “wah-wah” sound that is often used in guitar and bass processing.
Envelope Filter
Envelope filter is a type of filter effect that is similar to wah-wah, but it uses an envelope follower to track the amplitude of the input signal instead of the volume. This creates a similar “wah-wah” effect, but it is more responsive to changes in the amplitude of the input signal. Envelope filter is often used in vocal processing to create a “talk box” effect.
Equalizer
Equalizer is a type of filter effect that is used to boost or cut specific frequencies in an audio signal. It works by using a graphic equalizer or parametric equalizer to selectively remove or enhance certain frequencies in the signal. Equalizers are often used in mastering to correct frequency imbalances in a mix, or to add emphasis to certain instruments or elements in a mix.
Time-Based Effects
Delay
Delay effects processors are a type of effects processor that can simulate the delay of a signal for a specified period of time. This type of effect can add depth and dimension to a sound by creating a sense of space and movement. Delay effects can be used in a variety of applications, including music production, sound design, and live performance.
In music production, delay effects can be used to create a sense of space and movement in a mix. For example, a slight delay can be added to a drum track to create a sense of ambiance, while a longer delay can be used to create a rhythmic effect. In sound design, delay effects can be used to simulate the echo of a sound in a physical space, such as a room or hallway.
Delay effects processors can be simple or complex, depending on the desired effect. Some delay effects processors have a single knob for controlling the delay time, while others have multiple controls for adjusting the delay time, feedback, and wet/dry mix.
Reverb
Reverb effects processors are a type of effects processor that can simulate the acoustic properties of a physical space. This type of effect can add depth and space to a sound by creating a sense of ambiance and reflection. Reverb effects can be used in a variety of applications, including music production, sound design, and live performance.

Pitch-Based Effects
Pitch Shifter
A pitch shifter is an effects processor that allows the user to change the pitch of an audio signal without affecting its tempo. This is achieved by shifting the pitch of the audio signal up or down an octave or more, creating a new pitch that is either higher or lower than the original. Pitch shifters are commonly used in music production to create special effects or to change the key of a song without affecting its tempo.
Whammy
A whammy is a type of pitch shifter that is designed to create a dramatic pitch shift effect. It is commonly used in rock and metal music to create a “dive bomb” effect, where the pitch of the audio signal is rapidly shifted downward to create a dramatic effect. The whammy can also be used to create a “talk box” effect, where the pitch of the audio signal is shifted up and down in time with the vocals, creating a unique and expressive sound.
Harmonizer
A harmonizer is an effects processor that allows the user to create multiple pitches of an audio signal, creating a harmony effect. It works by taking the input audio signal and generating multiple copies of it at different pitches, creating a chorus or choir effect. Harmonizers can be used to create a variety of effects, from subtle enhancements to dramatic changes in the sound of an instrument or voice. They are commonly used in music production to add depth and dimension to a mix, or to create special effects such as unison or octave doubling.
Combining Effects
Multi-effects processors
Multi-effects processors are devices that combine several effects in one unit. They offer a wide range of sounds and are ideal for beginners who want to experiment with different effects without purchasing multiple pedals. These processors typically have presets that allow users to switch between different effect combinations, making it easy to change the sound of their instrument.
