The PS-6 can generate two or three voices, such as direct/third/fifth, in each of the following modes: Pitch Shifter, Detune, and Harmony. This will add rich depth to your guitar sound. Detune broadens the sound in a natural way, as the PS-6 allows 3-voice detuning with slightly raised and lowered pitch added to the direct signal. Voices can also be pitch-shifted one octave up and a fifth below your note — great for arpeggio-style playing, for example.
