  "description": "An intelligent harmonizer: a second voice a third, a fifth or an octave from each note you play, kept in your key and scale, so the harmony moves the way a second guitarist's would instead of in fixed parallel steps. It follows the note you play and tunes the voice to the scale note exactly. Key turns from C (all the way down) through every semitone to B (all the way up). Single notes, as the pedals that do this ask.",
