What is an octaver effector?

What is an Octaver?

An effector that can simultaneously play notes one octave lower (or higher).
*Some models cover up to two octaves lower

An "octave" is a note with the same name but in a different range. In terms of degree, it is a perfect eighth.

An octave lower also enters the bass range, creating a unison sound.

Also, if you go up an octave, you can create sounds reminiscent of synths or organs.

Octaver Effects | Connection Order

Among the effects, the octaver isPitch ShiftIt is classified into.

The general connection order is:Positioned just after the volume pedal, before distortion.

However, many people also use it after distortion, so ultimately it's down to preference.

The general theory is that it should be placed as close to the beginning as possible of the earlier effects.

Octaver Effects | Top 5 Picks

Electro-Harmonix Nano POG

Product details

The NANO POG is the smallest in the POG series of polyphonic octave generators, and is designed to take up as little space as possible on your effects board.

Like other POG series pedals, the tracking and sound are impeccable. The DRY, SUB OCTAVE, and OCTAVE UP controls, as well as the lack of switching noise, further enhance the pedal's perfection.

●Ultra-space-saving design that doesn't take up much space
Perfect tracking for chords, sweeps and single notes
●Realizes a deep bass sound like a 12-string guitar or bass
Beautiful organ-like sound
●Adjustable volume of original pitch and upper and lower octaves
Equipped with output jacks for dry sound and effect sound
●Adapter JP9.6DC-200 included

Electro-Harmonix / POG2

Product details

The popular POG has evolved even further since its release, with effects reminiscent of an organ sound!

Like POG, it responds accurately and smoothly to not only single notes but also chords, and can mix five heavy octave sounds (+/- 18 octaves) like synths, organs, and 5-string guitars. The algorithm has been strengthened to improve harmonic performance.

You can also control the attack, tone, and detune of each voice, fade in the octave sounds with the attack delay, create deep low frequencies with the low-pass filter with switchable Q mode, and use the detune slider to create original sounds.
Up to eight programs can be stored on the main unit, allowing you to quickly change settings even during a live performance.

This is a heavy and musical multi-octave unit that is recommended for guitarists looking for unique effects!

Newly developed tracking technology delivers a more accurate, natural feeling with no latency.

In 1982, the OC-2 debuted as the world's first modern octave pedal.
Its warm, powerful sound can be heard on many historic albums, and it continues to be loved today by guitarists and bassists around the world.
The OC-5's VINTAGE mode uses cutting-edge tracking technology to deliver the iconic monophonic sound of the OC-2 with a more natural response.

The OC-5 is capable of obtaining a +1 octave sound in both VINTAGE and POLY modes.
It can be used in a variety of ways, such as simulating the brilliant sound of a 12-string guitar, combining it with a -1 octave sound to add thickness to chords, or even adding a +1 octave to create a fat unison sound that adds presence when playing solo.

■ GUITAR/BASS switch and DIRECT OUT jack
By switching the GUITAR/BASS switch on the pedal itself, you can optimize the tracking engine for guitar or bass, delivering the best performance.

tc electronic / Sub 'N' Up Octaver・Mini

Product details

The Sub 'N' Up Octaver is a next-generation octave processing pedal developed based on TC's advanced pitch detection algorithm. Equipped with independent control knobs for dry mix level, octave up, 1 octave down, and 2 octaves down blend control, it provides an octave effect that follows complex chord playing and single note solo lines with ease. You can fully customize the pedal's controls and add modulation to the octave sound using the free TonePrint editor.

- Equipped with a next-generation octave processing engine that achieves perfect polyphonic (chord) tracking
- Classical monophonic octaver effects can also be reproduced
- Use the TonePrint function to add modulation to the octave tones

Toggle Switch
You can switch between three modes: "POLY" mode, which enables polyphonic tracking of chords, "CLASSIC" mode, which is ideal for classical single-note octave playing, and "TONEPRINT" mode, which allows you to use custom octaver settings via the free TonePrint editor.

●Polyphonic octave using the latest pitch shifting technology
Sub 'N' Up is equipped with the latest polyphonic pitch detection technology, allowing for ultra-fast and smooth tracking, and seamless octave effects even when playing chords. From the sparkling sounds of a 12-string guitar to the thick sounds of classic sub-octave riffs, Sub 'N' Up is the perfect tool for creating a range of effects.

Old school monophonic octave
Sub 'N' Up also supports monophonic octaves for single notes. It is effective for producing pseudo bass lines on guitar. Setting the knobs one octave down and two octaves down to a larger setting will give you a powerful low.
