The T-Rex Quint Machine is an octaver that not only lets you jump or stack an octave below or above your initial note – but also lets you add a +1 fifth harmony. Adding a fifth up or playing in octaves means that you can replicate organ 12-string guitar sounds alongside many more – opening up a huge array of sonic possibilities. On the face of the pedal are individual controls for each octave option plus a master Mix control. The Quint Machine gives you ultimate control over your octaver tone.

Octave Pedals

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.
