The BOSS PH-3 Phase Shifter pedal offers a wealth of vintage and contemporary phasing effects, including Rise and Fall modes for unique, unidirectional phasing. Syncing the PH-3’s phasing effects is as simple as tapping the pedal to the desired tempo, while an optional expression pedal provides realtime control of the PH-3's Rate, Filter and Tempo. In addition to standard up and down cycles, the Boss PH-3 Infinite Phaser can produce entirely upward or downward moving sounds through its Rise and Fall effects. There’s also 4-, 8-, 10-, and 12-stage phasers, plus a Step effect.
