PHASER Pedal? Everything & More!

All guitarists enjoy being able to add effects to their playing, but for beginners, this topic can be very confusing. Mainly, because there are so many different kinds of effect pedals, each having so many functions! Choosing the best for your need and style can be overwhelming!

Phaser Pedal Types? There are two types of phase pedals. These include both the analog and digital pedals. Whilst the analog pedal produces the sound organically the digital imitates the effect. However, the digital effect does not usually sound as good.

In this article, I will give you some basic information on the effects of Phaser Pedals… So let us get started!

1. What is a Phaser Effect?

A phaser is a type of modulation effect (like a flanger and chorus pedal). The phaser sounds like a swooshing sound (just like the wind). This effect is achieved by the signal going through a time filter, giving you an impression that the sound of the guitar is moving away and coming back in.

A phaser pedal, or phase shifter, is one of the earliest invented effects and massively popular in the 70s for getting that psychedelic funk sound.

The types of phaser effect can be a pedal, rack, or Plugin (emulator):

  • Analog phaser effect Pedals – Analog phaser effect Pedals can be either foot-controlled device or a rack. If you are gigging then you will need the pedal. Else if you are recording you will use the rack unit. This is because Rack Units have a better sound quality but they cost a quite pretty penny or are too advanced for someone who just has a basic need.
  • Digital phaser effect – Digital phaser effect pedals can be foot-controlled, rack, and a plugin. This is because of breakthroughs in technology, the digital phaser effect is basically a computer that simulates what the real effect should sound like.

Even though there have been some really good breakthroughs in technology the analog is more respected. However, you can still find really good digital effects on the market!

2. The Phaser Pedal – How it works

Technically, A phaser will take a dry input sound wave, duplicate and move it into something called an All-pass-filter.

This takes some of the frequency and reverses their phase. And when they’re blended back with the original, it creates these peaks and notches in the signal.

The Low-Frequency Oscillator (LFO) controls the frequency rather than the delay time of the duplicated wave that makes the phaser sound wavy and doppler-like.

A phaser uses more than an All-pass-filter in a chain that creates different amounts of stages leading to various phased sounds.

A digital phaser pedal usually has 4, 8, 10, or 12 stages. Alternatively, an analog phaser usually has fewer phase stage settings.

3. Example of the Phaser Sound 

 Listen to Eddie Van Halen’s “Atomic Punk” to feel the Phaser Effect.

4. Where to Put Phaser In the Signal Chain?

We can categorize effects in different ways. But the phaser is categorized as a Modulation Effects or Mods.

This is a kind of effect that modifies the sound in a certain way: by adding a time-delayed version of the sound to itself and then varying the size of that delay over time.

  • Spectral effects—Compression, EQ and Panning
  • Modulation – Wah Wah, Phaser, Flanger, Chorus, Pitch, Octave
  • Dynamic effects— Distortion
  • Time-based effects—Reverb, Delay, and Echo
  • Filters – High pass, low pass

As you can see above, the modulation effect wants to come after spectral effects such as distortion, but before dynamic effect to get a more realistic sound.

5. Phaser vs Flanger vs Chorus

You may find it a little bit confusing when getting used to the sound of a phaser and other effects like flanger or chorus. And they are indeed quite similar.

  • The flanger is when the signal is duplicated, one of them is delayed in time very slightly, usually no more than 20 milliseconds. That’s why a flanger gives a more dramatic and complex harmonic on your tone and you can change the intensity of the effect by raising the delay time with a pedal’s knob. Listen to Eddie Van Halen’s opening riff on “Unchained” for a great example of the flanger’s jet plane-like effect.
  • The chorus effect is similar to a flanger in that it creates two clones of the signal. The difference is that a chorus pedal uses a longer delay between the two signals, which creates a more subtle effect than a flanger or phase shifter 

6. How to Effectively Use Phaser Pedals

There are many types of phaser pedals with many added functions to suit your need as a basic or an advanced user. But here are some common control modes that are most likely to be found on a Phaser.

  • Speed/Rate: This knob controls the speed of the LFO that affects the number and position of the all-pass-filter chain. A low rate gives you a little wavy sound effect, but when you turn the knob to the right, you will experience some high-tech doppler-like sound.
  • Level: or “wet/dry” mode controls the intensity of the effect which applies to the duplicated dry input signal. The more intense this mode, the more squeezing sound you will hear.
  • Dept: the peak and troughs in the all-pass filter will change when you manipulate this knob.
  • Feedback: Like the term “feedback”, this mode controls the output signal that is fed back into the input. This can be used as a sub distortion effect to give it a more dramatic and noisy overtone.

There are actually no real rules to using a phaser due to your different styles and needs. The speed knob simply affects the troughs and the peaks in the sound that you hear. Whenever you turn it up too high, the sound will begin to be chaotic. But here are some basic suggestions for you when you are not too familiar to a phaser

7. Settings 

If you’re a fan of a vintage sound, the settings with Rate: 3/Depth: 8/ Feedback: 0/ Stage: 4 will suit you the best.

If you’re into more like a modern rock sound, these settings Rate: 7/ Depth: 4/ Feedback: 4/Stages: Between 8 and 10 may please you

Note: These settings will vary slightly dependent on the available functions on the phaser you purchase. This is just a general idea.

7. Best Pedal Phaser in the market with pros and cons. What would be a good fit for you?

1. TC Electronic Helix

Since being introduced in 2011, TC Electronic Helix Phaser soon became a hit due to investment in the core foundation features and the ability to add individualized functions for the user’s experience. You will find this phaser not too crowed with function knobs, no stage listed, but there are three modes you can easily switch on the board from Vintage, TonePrint to Smooth. With TonePrint editor, this digital pedal brings you a warm, good-quality sound like an analog one.

However, it’s also kept some of the basic functions such as speed and depth, which are familiar to a regular phaser, a mix that controls the effect intensity on the dry signal and feedback. The flexibility to create your own unique sound and style and the competitive price on Amazon makes the TC Electronic Helix Phaser an ideal one to put on your list

Helix would be a perfect match for fans of modern rock, rhythm, lead and most basic styles.

So-called “the holy grail of analog phasers”, Moog Moogerfooger MF103 12 Stage has plenty of excellent aspects to win the title. Designed by Bob Moog himself, it integrates a 6-stage/12-stage phaser and a multi-range LFO together, and it’s beyond an analog one. This can be quite sophisticated to be manipulated by a new-in-town host, but it’s worth it if you want to create your own styles.

With a 12-stage mode, you will experience a dynamic sweeping, sci-fi effects that bring a motion, third-dimension-like to the guitar sound. There are three dips – 2/4/6 – in 6-stage mode, while 12-stage has six. This also provides various feedback features that you can easily increase the resonance for the effect. Two knobs in the LFP controls the rate and depth of the pedal. There are also two smaller knobs in the middle that controls the mono input and the stereo output level
