Best Octave Pedal: 8 Options To Add Depth & Harmony

Creating music involves not just melody and rhythm, but also the texture and depth that different instruments provide. That’s where choosing the best octave pedal comes in, which is a tool that can add significant richness to your sound. An octave pedal is a type of guitar effects pedal that can duplicate the notes you play in higher or lower octaves, essentially allowing a single instrument to fill in more sonic space, almost mimicking a bass or a 12-string guitar. These pedals can be particularly effective in a solo performance or in a band setting where it’s desirable to thicken the overall texture of the music.

As with any specialized gear, the choice of an octave pedal is critical as it can greatly influence your sound. What makes an octave pedal stand out is its tracking ability — how quickly and accurately it replicates the played notes in different octaves without latency or glitches. Some models offer multiple octave divisions, while others provide additional effects like distortion or modulation to further enrich the sound. Durability and ease of use are also key, as a pedal must withstand the rigors of regular use and be intuitive enough to tweak during a live performance.

When considering the purchase of an octave pedal, it’s essential to pay attention to the quality of the octave effect, the range of the pedal (how many octaves up and/or down it can go), and its fidelity (how well it maintains the quality of your original sound). Depending on your setup, you might also want to consider the pedal’s true bypass status, which ensures that when the pedal is off, it doesn’t affect your signal. The versatility in blending the dry signal with one or multiple octave effects is another aspect to consider for obtaining the desired sound.

In our rigorous exploration of octave pedals, we sought the best models that provide not only a robust range of options but also the clarity and responsiveness necessary for professionals and hobbyists alike. We tested numerous offerings in the market to identify the ones that stand out in performance, reliability, and user experience.

MXR Poly Blue Octave

MXR Poly Blue Octave

We believe the MXR Poly Blue Octave is a versatile tool, sparking creativity with its mix of modern and classic tones.


  • Offers a harmony of modern and vintage octave sounds
  • Provides precise level controls for four octave divisions
  • Polyphonic/monophonic modes enriched by MXR’s legendary fuzz


  • Potential mechanical issues with the on/off switch
  • Can be considered pricey for budget-conscious musicians

Our recent jam with the MXR Poly Blue Octave pedal reminded us why it’s a staple on many pedalboards. Its dual personality, seamlessly blending polyphonic voices and a nostalgic fuzz, provides a palette of sounds that inspires endless experimentation.

In our session, the pedal’s performance stood out. Individual level controls for each octave allowed us to sculpt the mix, leading to a unique soundscape every time we engaged the pedal. The poly mode maintained note clarity, even in chordal work, while the mono setting introduced a raw, singular voice that cut through the mix.

We did note that some users have mentioned mechanical snags with the pedal’s switch, but these instances seem isolated and MXR’s customer service has a reputation for prompt resolutions. While the price tag is not for the faint of heart, it’s clear you’re investing in a pedal that’s both a workhorse and a show pony.

However, remember that to unlock the pedal’s full expression capabilities, you’ll need to grab an additional expression pedal or tap switch. Despite this, we found it an exhilarating addition to our gear, punching up solos, and underpinning riffs with gutsy, resonant octaves.

On the flip side, we found the versatility of the OC-5 to be a double-edged sword. While it’s an asset to have so many options underfoot, it can be a tad overwhelming for those who prefer simplicity. Nevertheless, after navigating the initial learning curve, we believe its depth adds to rather than detracts from its value.

In all, for those looking to push their musical expression with robust octave shaping, the OC-5 is a champ. It serves up vintage vibes or modern polyphony with equal finesse, making it a dynamic addition to our pedalboard.

We’ve found that the JHS 3 Series Octave Reverb is a reliable pedal that enriches your sound palette without breaking the bank.


  • Rich, shimmering tones suitable for expansive soundscapes
  • Versatile with distinct upper and lower octave controls
  • Compact size and robust build quality

Upon first use, we were immediately drawn into the lush and almost ethereal reverb that the JHS Pedals 3 Series Octave Reverb delivers. Its ability to layer sounds in both upper and lower octaves creates an immersive experience that’s as impressive in a live setting as it is during studio work.

Tweaking knobs on the fly felt intuitive, and the range of ambient textures we could achieve was surprisingly broad considering its simplistic interface. Switching from soaring high-octave to the sonorous depths of low-octave reverb adds considerable depth to any player’s repertoire.

Durability seems like a non-issue as well; with its solid construction, we’re confident it would withstand the rigors of gigging. It’s clear JHS has designed this pedal not just as a tool for guitarists to use, but as a companion that encourages exploration within the musical universe.

JOYO Octave Pedal XVI

JOYO Octave Effect Pedal

We found this pedal delivers a robust octave effect perfect for musicians who love to add richness to their sound without breaking the bank.


  • Easy to use with independent octave control.
  • Feels durable and sports both modern and retro design elements.
  • Provides pleasing MOD effects that enhance playing versatility.


  • May introduce some unwanted noise if not properly set up.
  • Requires careful power selection for optimal performance.
  • External power adapter not included, may necessitate additional purchase.

Our time with the JOYO Octave Pedal was quite enlightening. The dual knobs for octave adjustments afforded us the convenience of dialing in the perfect blend of higher and lower octaves, which has the potential to enrich melodic lines or add fullness to chords. Striking a balance between simplicity and control, it didn’t take us long to incorporate it into our pedalboard setup.

Durability is never a secondary thought, and the JOYO Octave Pedal feels solid with its metal construction. The stylish design, merging the futuristic vibe with a touch of retro, catches the eye and would stand out on any stage or in any studio. This pedal isn’t just about looks; the MOD effects on hand offer tasteful additions to our sonic palette, inviting experimentation.

However, it’s worth noting that, during our sessions, we encountered a bit of noise. While this is not uncommon in the realm of effect pedals, potential buyers should be aware that proper setup and a good quality power supply are crucial to minimize this issue. Although the lack of a provided adapter is a minor inconvenience, investing in a reliable one is a sensible move for any serious musician.

FLAMMA FS08 Octave Pedal

FLAMMA FS08 Octave Pedal

We find that this pedal is a versatile choice for guitarists who yearn for richer soundscapes with straightforward functionality.


  • Provides a wide range of octave effects
  • Solid build with easy-to-use controls
  • True bypass maintains signal integrity


  • External power supply required, not included
  • May introduce noise with USB-powered instruments
  • Color and design might not suit all pedalboards

In our hands-on time with the FLAMMA FS08, we noticed its impressive ability to produce clear polyphonic octave effects, which can easily thicken your guitar’s sound or add a unique texture. Rotating the knobs, it’s easy to see the extensive range of octaves at our disposal, which range from subtle underlayers to bold, standout pitches.

The pedal’s full metal casing inspires confidence, standing up well to the rigors of foot-stomping musicians. It’s also quite compact, leaving ample room for other effects on our pedalboard. During a jam, engaging the true bypass ensures our signal remains pristine when the pedal is not in use.

However, it’s worth noting the absence of a power supply in the box, which necessitates a separate purchase. Moreover, some of us encountered an annoying buzz when using USB-powered tools alongside it, though this was remedied with a traditional power source. While the bright green hue pops, it might not mesh well aesthetically with every setup.

In all, our experience suggests that the FLAMMA FS08 offers both novice and seasoned guitarists an expansive suite of octave effects, deserving a place on many pedalboards for its musical flexibility and ease of use.

Donner Harmonic Square

Donner Harmonic Square

We’ve got our hands on the Donner Harmonic Square, and it’s clear that any musician seeking to add rich octaves and pitch variations would appreciate this pedal’s versatility and sound quality.


  • Versatile pitch-shifting options
  • Solid, durable construction
  • True bypass for uncolored tone


  • Power adapter not included
  • May introduce some latency
  • Limited tweaking options compared to larger units

Having just played around with the Donner Harmonic Square, we were struck by the breadth of sonic options it put at our disposal. With seven different shift types and three tone modes, it’s like having a Swiss army knife for pitch at your feet. Whether we needed a sub-octave growl or a shimmering twelve-string effect, this pedal handled it all with ease.

We found the build quality to be reassuringly robust. The all-metal chassis feels like it can withstand countless gigs and rehearsals without a hiccup. And maneuvering through settings was a breeze, thanks to the clear layout of knobs and switches.

In practice, the true bypass feature meant our tonal purity was never compromised when the pedal was off. However, we observed that it’s best to anticipate a short learning curve to fully exploit its capabilities, especially during a live performance. Despite this, once we got the hang of it, the amount of creative expression this pedal afforded us was impressive, to say the least.

For guitarists and bassists looking to expand their tonal palette without breaking the bank, the Donner Harmonic Square is a smart choice. While it doesn’t include a power adapter, and nuanced sound tinkerers might crave more knobs for fine-tuning, the pros far outweigh the cons, making it a worthy addition to any pedalboard.

SONICAKE Octave Pedal

SONICAKE Octave Pedal

We find the SONICAKE Octave Pedal a solid addition for guitarists aiming to thicken their sound palette with reliable octave effects.


  • Generates rich and authentic octaving with minimal latency
  • True bypass design ensures your tone remains uncolored when disengaged
  • Compact and sturdy design easily integrates into any pedalboard


  • Requires a separate 9V power supply not included in the package
  • Limited to monophonic tracking, so complex chords may not track accurately
  • The all-analog circuit may not offer the versatility some digital models provide

When we integrated the SONICAKE Octave Pedal into our setup, the first thing that struck us was its ability to produce a warm, vintage octave sound that complements a range of styles from thickening up solos to laying down those subterranean riffs that captivate an audience. The pedal’s compact form made it effortless to add to our already crowded pedalboard, and despite its sturdy build, it didn’t weigh us down either.

The true bypass wiring is another thing we value; we could add the octave effect into our signal chain without any concern for tonal loss when the pedal was turned off. For the guitarists who crave sonic purity, this is a feature that can’t be overstated.

However, during our playthrough, we did notice its limitations when dealing with polyphonic textures. While this pedal excels at handling single-note runs, players who look to apply octave effects to complex chords might encounter some glitches. Those looking for an octave pedal with polyphonic tracking might want to consider other options.

We also were reminded repeatedly about the necessity of a 9V DC power supply, as this pedal doesn’t come with one. For players who don’t already have a dedicated power supply, this could be a slight hurdle to immediate use. Despite this, the sonic qualities and build of the SONICAKE Octave Pedal left us generally impressed. It’s a pedal that delivers a significant bang for the buck especially for mono line-playing enthusiasts.

Behringer UO300

Behringer UO300

We believe the Behringer UO300 is a great addition to any pedalboard for guitarists looking to add some depth and power to their sound.


  • Adds significant depth with 1 and 2 octave-down effects
  • Tailor your tone with separate controls for each octave and direct signal
  • Versatile 3-mode range switching caters to various playing styles


  • Plastic construction may not withstand heavy stomping
  • 9V battery or external power supply required, not included
  • Limited to octave effects, without additional harmony capabilities

After spending some quality time with the Behringer UO300, our first takeaway is the remarkable depth it injects into your sound. The ability to add one or two octaves below your original note can turn simple riffs into sonic giants. It’s like having a bass player shadowing your every note, which fills out the mix in both live and studio settings.

We appreciate the control this pedal offers. Each octave effect has its own volume control, giving you the power to shape your sound precisely. The direct signal also has its own knob, maintaining the integrity of your guitar’s tone while blending in the chosen octave effects.

The pedal’s 3-mode range switch is a standout feature. It allows us to tweak the pedal’s response to suit various frequency ranges, which means you can adapt it to different playing styles and setups. Whether you’re playing chunky riffs or soulful leads, the UO300 serves up a sound that supports rather than overpowers.

However, the pedal’s plastic body does make us cautious. While perfect for bedroom practice, those who gig regularly may question its durability. Furthermore, the fact that it doesn’t come with a power supply means you’ll have to factor this into your setup. Lastly, if you’re looking for harmonies or detuning options alongside octave effects, you might find the UO300’s functionality a bit limited.
