  • Digital circuit design, true bypass

The Donner Harmonic Square Octave is an octave and pitch shifter pedal that will work great with any six-string guitar, 4-string bass guitars, baritone guitar, etc. It offers three modes of operation. By using its toggle you can choose between Sharp, Detune, and Flat. Each of these delivers a different flavor of octave and lets you explore a myriad of sounds.

The Donner Harmonic Square has 7-octave modes that you can switch by turning the main knob: ±2, ±3, ±4, ±5, ±7, 1 octave, and 2 octaves. All of this is housed in a very compact aluminum alloy chassis that will easily fit on any pedalboard and be able to take road and gig punishment.

This pedal offers three knobs (2 tiny and one normal) and a toggle switch to allow you to be in full control of your sound at all times. One of the tiny knobs is labeled “Wet” and sets the volume of the effected signal.

The other tiny knob (Dry) sets the volume of your original sound. The toggle will produce the most drastic changes in sound as you can change it to choose between the Sharp, Detune, and Flat modes to dictate the amount of pitch-shifting you wish. The big knob (the encoder) will allow you to choose to go up or down by the desired semitones, as well as 1 or 2 octaves, all in a simple to use fashion.

The Donner Digital Octave is one of the best octave pedals, especially if we consider its features, tiny size, and price.

3. Electro-Harmonix Micro Pog (Premium Option)

The Micro Pog Polyphonic Octave Generator stems from the original POG (a legendary and award-winning EHX octave pedal). The Electro-Harmonic Micro POG delivers the same perfect tracking and smooth polyphony in a simplified design and is our premium option for octave pedals.

  • Adjustable original pitch volume
  • Adjustable octave down/up volume
  • Generates multiple octaves
  • Sturdy, compact enclosure


The Micro POG is a leaner and meaner version of the classic EHX Polyphonic Octave Generator, redesigned with buttons instead of the eight sliders featured on the original. It allows you to create new tones by mixing together your original dry signal with two different octaves, one above and one below your original pitch.

All of this is accomplished with a simple set of controls that lets you quickly dial in your sounds. This pedal is digital and features tighter and quicker tracking than the original POG.

This octave pedal allows you to blend an octave below and octave above a given note, balancing the sounds with the responsive controls. A single input and two outs allow you to split the dry and wet signals.

This is a musical octaver without unwanted glitches in lower notes and chords, allowing you to transform your electric guitar into a 12-string, a bass, or even a church organ.

The original POG features an additional octave up, which is not featured on the Micro POG. However, this pedal comes in a much more compact enclosure and with simpler and more streamlined controls than the original, while still offering great tone and the ability to easily blend octaves in a variety of ways, from subtle tones to experimental sounds.

View Price On Amazon ViewPrice On Guitar Center

It comes with eleven different octave settings with up to five available octaves in a single setting.

  • True bypass


The Mooer Pure Octave is the smallest pedal on this list. It features a large rotary knob that lets you select among 11 different octave modes, with different combinations of one and two octaves above and below. The blend is added via the volume knobs for dry sound, the sub-octave, and the upper octave.

This pedal offers a variety of sounds that can be useful in many contexts and styles. The tone of the octaves sounds as natural as possible for octaves that are clearly outside the reach of a standard guitar. Two octaves down produces a deep throaty sound that will require a larger speaker.

A single octave up produces bright tones that are very guitar-like, without the grit or limited neck range of typical analog octave effects. Two octaves up produces a piercing, more brittle tone that gets into synth-like territory.

The appeal of this octave guitar effect pedal stems from the various combinations it offers. The slight volume modulation that accompanies the octave down adds a bit of movement to the dry signal and sills out the frequency spectrum in the second octave down. You can also combine the octave-up with the dry signal to produce a believable 12-guitar sound. If you want a pipe organ sound, add a second octave up.

This pedal tracks very well has no latency issues and is always on pace with the player. All the notes open, sustain, and decay naturally without glitches or unwanted artifacts, making the Mooer Pure Octave a solid choice for the guitarist that wants a good octave pedal in a tiny enclosure.
