Boss PH-3
Boss · pedal
The Boss PH-3 Phase Shifter is a multi-mode phaser pedal offering four-stage, eight-stage, ten-stage, and twelve-stage phase settings plus Rise, Fall, and Step modes for a total of seven independent phase configurations. Controls include Rate, Depth, and Resonance, plus tap tempo via an external switch. An optional expression pedal provides real-time control of Rate, Filter, or Tempo. Step mode creates a synth-like stepped phase effect rather than a continuous sweep. Suited for classic rock, psychedelic, and modern experimental playing styles.
What stands out
“The PH-3 offers an unusually wide range of phasing textures from classic vintage four-stage sweeps through dense twelve-stage flanging-adjacent sounds to stepped synth-like phase, covering more tonal territory than most phasers”
