Buyer’s Guide

With so many pedals, how do you know which ones are worth buying? Finding the right phaser will come down to the sound you want to create and how much control you want over the effect. Here’s our guide to choosing the right pedal for you.

What makes good controls in a phaser pedal?

The most significant difference between phasers lies in the available controls for altering the effect. Nearly all pedals will have a speed or rate control for adjusting how fast it is applied. Sometimes this is the only control available, although it is common to have some switch for swapping between multiple phaser stages. 

The higher the number of stages a phaser has, the more intense the overall effect will be. Below are a few other controls you can find on a phaser, as well as what they do: 

  • Level/Blend – controls the mixture of wet and dry signals. Allows you to make the phase shift more or less subtle. 
  • Depth – Controls the peaks and troughs of the waveform. High depth will make your sound more warped and distorted. 
  • Feedback/Resonance – Affects how much of the output signal is fed back into the input—used to create more distorted other-worldly effects. 

How big should my phaser pedal be?

Another factor to consider when choosing a phaser is its size. If you own a pedal board with a large selection of other effects, you will need to consider how much room you have left for a new phaser. Larger pedals will often have more controls, allowing you greater control over your sound. 

Smaller pedals are easier to fit on a board and in your guitar bag when you want to take them to a gig. It comes down to a question of how much functionality you want from your pedal and how much space you have available on your board. 

Stomp-box vs. button switch – which is better?

If you don’t like looking at your pedal board every time you want to change settings, a stomp box might be perfect for you. 

These devices have larger switches shaped like a classic foot pedal, making them much easier to hit without needing to look. They can also be more durable since they are designed to be stomped on. 

Button switches can be a little trickier to hit accurately with your foot. However, they are also generally used on much smaller pedals, making them more portable. 

They are also easier to activate with a slight tap from your foot. While you shouldn’t stomp on a button switch, they are often quite durable and built to withstand a bit of punishment.

Both switches have their benefits and drawbacks, so which you select will come down to personal preference. 

Frequently Asked Questions

What Is A Phaser Pedal?

A phaser pedal is part of the modulation family of guitar effects. It takes one specific aspect of your instrument’s dry signal’ (the signal before any effect is applied) and alters it at a constant rate to form the ‘wet signal.’ 

In the case of a phaser, the pedal cuts the high-end frequencies of your input. These cuts modulate up and down to create the weird, sci-fi sound effects for which these pedals are known. 

Overall, these devices constantly alter the tone of your instrument to create an oscillating reverb that is less consistent than a chorus but more controlled than a flanger. 

What Is A True Bypass On A Guitar Pedal? 

Many guitar effect pedals will have what is called a true bypass switch. This bypass is the button or foot pad you press down to activate the effect. 

The term true bypass refers to a switch that won’t affect your ‘dry signal’ when in the off position. This means that you won’t encounter distortion or interference when the pedal is not activated. 

This switch is essential for musicians who use a lot of pedals. Without true bypass switches, the impedance of each device would negatively affect the clean signal from the instrument. 

True bypass switches offer a genuinely pristine clean signal when they are not actively applying an effect to your output. 

What Does A Phaser Pedal Sound Like? 

Phasers create swirling sounds that give the illusion of movement. You can use them to create low-to-high sweeps and jet plane eruptions, warbles, and wails. 

At their subtlest, slow phasers provide a thickened sound. At their most intense, they produce a range of chaotic, sometimes melodic, and sometimes discordant, overlapping notes. 

They enhance the presence of your instrument and work into multiple different genres of music, including funk, psychedelic rock, and even metal. 

What Famous Musicians Have Used Phaser Pedals? 

The first rackmount phaser effect was invented in 1971 and was called the Instant Phaser model PS 101. 

This effect was then made into a compact pedal, the first of which was the 3-speed Maestro PS-1 Phase Shifter invented by Tom Oberheim. 

Since these early beginnings, this effect was frequently used in music production throughout the 70s and 80s. Eddie Van Halen, Tears for Fears, Billie Joel, The Eagles, and Rush are just a few famous bands and musicians who use phasers in their music.
