Buying Guide: How To Pick The Best Phaser Pedal For You

If you’re still not sure about which phaser pedal is right for your pedalboard, then here are some important things to keep in mind:

Sound Signature

Phaser pedals offer a wide range of sounds, from smooth and rounded, to gritty and choppy, and with different ranges of rates and intensities. Some might have just one mode, while others may have multiple modes and toggle switches to choose from, giving you a lot more versatility. The main differences in phaser pedals often arise from the type of low-frequency oscillator (LFO) used, and the waveform produced by them. There are also other variations amongst phaser pedals; some have analog circuitry while others have digital circuitry (3).

Analog pedals offer more authentic vintage phase sounds, whereas digital ones offer modern flexibility.

Hence, you should go for a phaser pedal that offers the exact tones you need, whether you want a flexible pedal that may have digital circuitry, or a simpler, analog one with more authentic, classic phaser sounds.

Controls And Power Requirements

Phaser pedals come with a wide range of controls, with some having only a single knob while others have 3 or even 4 knobs as well as toggle switches for different modes and functions. The standard control options commonly found on a phaser pedal generally consist of just a Rate, or Speed knob, such as on the MXR Phase 90, but some offer other controls wet/dry mix (or blend), feedback, depth (intensity of the phaser), tap tempo, etc. Depending on how you want to use a phaser, and whether you want to customize your sound in-depth, or just plug-and-play with one knob, you should opt for a comfortable pedal for you to use.

The power requirements of a phaser pedal are also a major consideration. Some phaser pedals can be powered by 9V batteries, which is great for portable, on-the-go usage, but some of them require a 9V DC power supply unit and have a higher current draw. Hence, depending on your usage cases (studio, live, or home use), your pedalboard’s design, your power brick, etc., you should pick a phaser pedal that will easily fit into your current pedalboard and also get enough power to run smoothly and noiselessly.

Bypass Type

Pedals with buffered bypass convert your signal from high impedance to low impedance, and then amplify it again to prevent any loss in signal strength while it flows through the pedal’s circuitry. This ensures a stable, consistent signal throughout your pedalboard. However, the problem arises when the buffer used is of low-quality (often found in cheaper pedals), which causes a sharp loss in brightness and integrity of the guitar sound (also known as ‘tone-sucking’) (4).

 In true-bypass pedals, your guitar’s signal is routed directly through the pedal circuitry without any alteration.

True bypass usually works best when you’re only using a couple of pedals and short cables. But adding more true bypass pedals means more cables, and that will result in a loss of brightness and treble along the signal chain, so you have to be careful about that.

Hence, depending on your pedalboard size and the length of your overall signal chain, different bypass modes may be required in different circumstances.

FAQs

A phaser pedal uses a low-frequency oscillator (LFO) to create a modulation effect, where it mixes two signals: a processed signal and an unprocessed signal. The processed signal is slightly delayed, and also passed through certain filters in a rhythmic manner (determined by the speed of the LFO). When this is mixed with your dry signal, it produces an ‘out-of-phase’ effect, which gives it the signature ‘swoosh’ sound, and adds a lot of texture as well.

You should put your phaser pedal at the end of your signal chain, much like other modulation effects. It should be after any overdrive or distortion pedals, and before any time-based pedals like delay or reverb, and can be placed alongside your tremolo and chorus pedals. But if you’d like to experiment, you can place it in different positions and see how it affects your sound.

A flanger and a phaser are both modulation effects that use an LFO and may often seem quite similar, but the difference between them lies in the way the signals are processed and filtered. Phasers use an ‘all-pass filter’ to filter the signal waveform in specific places, then an LFO delays the signal and places it on top of the dry signal. In a flanger, however, the delay time is shorter, and the filter used is a ‘comb filter’, resulting in more feedback.
