Essential Information About the MXR Custom Shop Script Phase 90 Pedal

  • The vintage "script" phaser revisited by the Custom Shop to regain the headroom, clarity, and swirl of the original late 1970s Phase 90s.
  • Legendary simplicity: a single "Speed" control to shift from subtle movement to a more pronounced rotation, without getting lost in menus.
  • Ready for the modern pedalboard: status LED + power input, while preserving the spirit of a classic analog phaser.
  • True hardwire bypass to preserve the signal when the effect is off.

The Return of the "Script": A Phasing Classic Updated

Often copied, rarely matched, the signature sound of the MXR Phase 90 "script" is a cornerstone in the history of effects pedals. Its original circuit helped define the phaser sound heard on countless recordings: a round, organic modulation with that immediately recognizable "liquid" movement. This MXR Custom Shop Script Phase 90 version aims precisely for that character: more clarity, better headroom before saturation, and a more restrained midrange bump for smooth and musical phasing.

A Phaser for Purists... and Anyone Seeking an Iconic Sound

This pedal is designed both for the guitarist who wants the perfect one-knob phaser and for the collector looking for the aesthetics and response of a vintage model without the constraints of an original. It excels in clean settings (funk, pop, neo-soul, jazz-fusion) to add depth to chicken picking and chords, but it remains just as convincing with overdrive or distortion to thicken a rock riff, add movement to a lead, or create a near "Leslie" rotary effect depending on the speed setting.

In the studio, it's a simple and quick tool to place a guitar in the mix. Live, it brings that "breath" and harmonic movement that make a part more alive without altering your attack.

Controls and Design: MXR Efficiency with the Right Modern Additions

The Script Phase 90 gets straight to the point: a Speed potentiometer controls the modulation rate, from subtle shimmer (ideal for thickening a clean tone) to faster, more expressive phasing. Activation is via the footswitch, with a status LED to keep control on stage.

Regarding integration, it features 6.35mm Jack input/output, a standard and reliable format for any pedalboard. The true hardwire bypass preserves your dry tone when the pedal is off, an important point if you rely on your amp's dynamics and right-hand touch.

Finally, the pedal runs on a 9V battery and can also be powered by a 9V DC external power supply, convenient for a stable and silent setup.

The Sound

The Script Phase 90 is above all an ultra warm and smooth phasing, with modulation that seems to "breathe" with your playing. Where some phasers can sound too pronounced or too "harsh," this one favors a round and musical rotation, with a sense of fluid movement rather than an intrusive effect. The result: you can use it constantly on a slow setting to thicken your tone, or push it for more psychedelic textures while maintaining excellent note clarity.

This type of phaser has marked guitar history and has been used by iconic guitarists, from rock to prog, thanks to its instantly identifiable character and ease of blending with saturated sounds.
