Boss OC-5 Octave Pedal Overview

Old meets new in the most versatile octave pedal yet. The Boss OC-5 is the new flagship octave pedal and sets a new benchmark. Building upon everything good about the previous models, the OC-5 incorporates innovative upgrades to deliver the new industry-standard in octave effects. These include a new dedicated octave-up control, Guitar/Bass selector switch, and variable range control to choose which notes get harmonised. The biggest upgrade, however, is the elimination of latency, so you don't need to worry about any delay between you playing the note and the octave sounding. Boss have upped the game with the OC-5, and created the most definitive octave harmoniser yet.

Key Features

  • Flick between old school OC-2 tones on 'vintage' and modern voicings on 'poly'
  • Add even more depth to your music with dedicated octave-up knob
  • Select which notes to harmonise using Variable Range control
  • Guitar/Bass selector switch for instrumental optimisation



Full Description

OC-2's big brother


Upgrading a classic. When Boss released the OC-2 in 1984, they changed the pedal landscape with a distinctive octave effect that earned its legacy as a cult classic. Now, with the Boss OC-5, they have changed the game once again. With 'Vintage' mode selected, the OC-5 perfectly recreates all the quirks of the original OC-2, just with a few revolutionary upgrades. No latency is the biggest of these - now you get instant octave response helping your playing be even tighter. Separate controls for -1 and -2 octaves also makes tweaking your sound much easier, and you'll likely find yourself spending hours dialling in different variations of octave goodness. A true classic reimagined for the modern age.

Boss' box of polyphonic tricks


Among the many updates in the OC-5 is Boss' new tracking engine for improved response. When the 'poly' mode is selected, these improvements become truly noticeable and you'll see instant synchronisation between the octave effects and your playing. This improved response is complemented by a clever new feature which is the Guitar/Bass switch, located on the top of the unit. This allows for simple optimisation of your sound based on instrument and again adds a level of intuitiveness simply not found on other octave pedals.


The variable range control is what really separates the OC-5 apart from the pack. Giving you total control over which parts of your sound get harmonised certifies the OC-5 as the most versatile octaver currently available. If you want full chords embellished with 3 octave harmony, leave the setting at max. However, if you only want the bass note affected simply set the range to 'lowest' and only the lowest note of each chord will have the octave applied. This gives you unparalleled control over harmony and gives the OC-5 its remarkable versatility.
