Boss PH3 Phase Shifter Effects Pedal

BOSS PH-3 Phase Shifter

Harness the hypnotic swirl of classic and modern phasing in a single compact pedal built for stage and studio.

The PH-3 Phase Shifter delivers six distinct modulation flavors—from vintage 2- and 4-stage warmth to dramatic 8-stage depth, slow-sweep ambience, and rhythmic step-phaser patterns—all dialed in with dedicated Rate, Depth, and Resonance knobs. A versatile tap/hold footswitch locks in precise tempos or unleashes manual sweeps on demand, while stereo input/output and EXP/CTL jacks let you integrate external expression pedals or switches for real-time control. Backed by BOSS’s rock-solid construction and affordable price, the PH-3 brings pro-grade phase performance wherever you play.
