The MXR Phase 100 is the bigger brother of the legendary Phase 90, offering a broader range of phasing sounds that will inspire every guitarist looking to add depth and movement to their tone. With its four-position rotary switch, you can select from four preset waveforms, allowing for a variety of spacey, psychedelic ambience perfect for both solos and chordal textures. Whether you’re aiming to add subtle shimmer or a swirling, dramatic effect, the Phase 100 provides versatile control to shape your sound with ease.

Four-Position Rotary Switch

The Phase 100’s standout feature is its four-position rotary switch, which selects from four distinct preset waveforms. This allows you to easily switch between phasing textures, offering everything from subtle movement to intense, swirling effects. It’s ideal for adding variety and expression to your playing.

Simple Yet Effective Controls

With just SPEED and INTENSITY knobs, the Phase 100 is straightforward to use but offers a wide tonal palette. SPEED adjusts the rate of the phase shifting, and INTENSITY shapes the depth and character of the waveform, giving you complete control over the effect’s presence and feel.

Versatile Power Options

Power the Phase 100 with a 9-volt battery, a compatible AC adapter, or a DC Brick™ power supply. This flexibility ensures you can easily integrate the pedal into any rig, whether at home, in the studio, or on stage.

True Bypass and Low Noise

Equipped with hardwire bypass, the pedal preserves your original tone when disengaged, ensuring no loss of signal quality. Its low noise floor means you get a clean, pristine sound free from unwanted hum or buzz.

Key Features

  • Four-Position Rotary Switch – Select from four different preset phasing waveforms to customise your sound and add dynamic textures to your playing.
  • Speed and Intensity Controls – Easily adjust the rate and depth of the phasing effect for versatile tones ranging from subtle to psychedelic.

MXR

MXR’s first product was the Phase 90, released in 1972. Dunlop’s official MXR history traces the early line from that compact phaser to the Distortion+, Dyna Comp compressor and Blue Box octave fuzz—circuits that remain central reference points for the brand. JustPedals carries those classic families alongside the Carbon Copy analog delay, Micro Amp, Talk Box and bass effects. MXR’s range is deliberately broader than one effect category: compare the model number and version, especially where a classic circuit has later reissues, mini enclosures or expanded controls.

Category

Phaser Pedals

A phaser splits the signal and shifts the phase of one path through a series of all-pass filter stages. When recombined, moving peaks and notches sweep across the spectrum, creating a rounded swirl rather than the evenly spaced comb filtering of a flanger. Stage count, feedback, centre frequency, rate and depth shape the width, resonance and pulse of the sweep.
