Meet the BOSS PS-6 Harmonist effects pedal, with four intelligent pitch-shift effects and three-voice harmony in one convenient unit. Among the effect modes are Harmony, Pitch Shifter, and Detune, plus the all-new Super Bend for authentic pedal-bending effects and wild 3- and 4-octave pitch sweeps. With the PS-6 Harmonist, you can even control pitch with an optional expression pedal.
The Harmony function is fast and simple to use, and supports a variety of interval patterns. It's easy to create rich, 3-voice harmonies: choose a major or minor key, and set the Shift to 3-VOICE-that's it! The PS-6 Harmonist is an unbeatable combination of superior sound quality, ease of use, and powerful pitch effects, all under one hood.
