Featuring the iconic, sturdy Boss enclosure and streamlined controls for rate, resonance and depth, the Boss PH-1R Phaser gives a striking but tasteful phased analog edge to your tone. Capable of adding a completely phased sound or low-end presence all without adding noise to your signal, the PH-1R is great for psychedelia, stoner rock, or garage.
