Octave pedals add or shift a note by one or more octaves, either as a blended voice or as a pitch-shifted output. Analogue divider circuits can have a raw, glitchy response, while digital designs may offer cleaner tracking, presets and polyphonic operation. Playing position, pickup type, low-frequency content and chord complexity all affect how stable the result feels. Check whether the effect is monophonic, whether the dry signal can be blended, and how much latency or artefact is acceptable. Octave fuzz, clean octave and octave-up harmony are different jobs despite the shared label.
