MXR Deep Phase

MXR · pedal

The MXR Deep Phase is an enhanced phaser pedal from MXR (Dunlop), delivering deeper, more dramatic phase shift than the standard MXR Phase 90 with an additional depth control for adjusting the intensity of the phase sweep. The Deep Phase takes the classic MXR phaser circuit and extends it with deeper, more modulated phase character for psych, classic rock, and funk applications.
