Phaser is the pedal that brings the phaser effect to your sound. The essence of the phaser effect is the mixing of an unprocessed signal with a processed signal, which has had its phase changed. This phase change process creates a set of peaks and valleys in the signal's frequency response, known as “notches”. As these notches move along the frequency spectrum, the listener perceives a sense of sweep or “swirl” in the sound.
