Harmony mode builds intervals that follow a chosen major or minor key. Two shifted voices can be added to the original note for three-part harmonies.

Pitch Shifter moves the signal up or down by as much as two octaves. Detune adds a slightly offset copy for a thick, chorus-like sound. A Balance knob sets the mix in every mode.

S-Bend creates pitch bends while the pedal is held, with separate rise and fall times. An expression pedal input allows real-time control of the shift. Two outputs are provided, and the pedal uses the standard BOSS compact enclosure.
