Pearl is, of course, first and foremost a drum company, but the pedals it made in the '80s are standout units. The PH-03 Phaser, a smaller version of the much-loved PH-44 Phaser, gives the same LFO-modulated phasing. Manual, Feedback, Depth, and Speed controls all let you fine-tune the modulation to your delight.
The Phaser creates the sound of a rotary speaker by electronically generating the Doppler Effect. Pearl PH-03 is equipped with a "Manual Control" which creates unique and various tonal colorations of the phasing tones.
