Description

Experience the smooth, vintage tones of the MXR M279 Deep Phase Pedal, a compact yet powerful addition to your music gear. Renowned for its high-quality build and tweakability, this pedal offers unique phaser tones reminiscent of the classic era of music. The pronounced swoosh, scooped midrange, and dynamic response to your attack makes it adaptable to different playing intensities.

The Deep Phase Pedal eliminates the volume drop issue found in the original, ensuring level matching when you kick the switch. Equipped with two knobs and a switch, it provides a wide range of phase tones - from subtle liquid shifting to intense swirling turbulence. The Speed knob adjusts the effect rate, while the FDBK knob modifies the phase peaks' intensity and sharpness.

Built for versatility, the Deep Phase Pedal features a Mode II switch, doubling the number of peaks and creating a more animated texture. Its compact and road-ready MXR mini housing ensures it takes minimal space on your pedalboard, making it a practical choice for touring musicians.

Key Features:

  • Expressive vintage phaser tones
  • Dynamic, voice-like attack response
  • FDBK knob for adjusting phaser intensity
  • Speed knob for controlling effect rate
  • Mode II switch for enhanced texture
  • Compact, pedalboard-friendly MXR mini housing
  • True Bypass for preserving signal integrity when the pedal is off
  • Controls for Speed, FDBK (Feedback), and Mode II switch
  • High-quality metal housing
  • Input and Output: 6.3 mm jack
  • Power consumption: 20 mA

Critic Reviews

Has MXR perfected the mini phaser pedal with the Deep Phase? | MusicRadar

musicradar.com

The MXR M279 Deep Phase pedal adds a delightful twist to the iconic Phase 90 with its extra controls and expanded phasing options. Musicians will appreciate the new FDBK knob for intensity and the unique Mode II feature, delivering a richer, more dynamic sound. However, some may find the price tag of $129.99 a bit steep for a mini pedal, and it might not fully replace the classic Phase 90 for purists. Still, for those seeking a fresh take on phasing, the Deep Phase offers versatility in a compact design.
