BOSS PH-3 Phase Shifter

Versatile Phaser Effects Pedal with Multiple Stage Modes
Unlock a spectrum of classic and modern phasing textures—from smooth, sweeping 4-stage tones to rhythmic, stepped patterns—while the RES control adds vocal-like peaks. Tap-tempo syncing and an EXP/CTL jack let you shape rate and depth in real time, and true bypass keeps your signal pristine when the effect is off.
