Best Octave Pedals

Top 10 Best Octave Pedals On The Market (July 2020)

Updated - June 27, 2020

In order to find the best octave pedals on the market we first need to understand the octave effect. Since the era of rock and roll, guitarists have tried to magnify their sound for the biggest effect. Octave pedals give guitarists and bassists a chance to push up that ‘sound scale’ a few more notches.

Working With The Octave Effect Pedal

Octave pedals work best with strong, clean tones. This is the ideal point from which they should pitch shift, whether it’s up or down. The best octave pedals perform well at the front of a pedal chain. The closer they are to the guitar the more accurate their note tracking capabilities will be.

What Type Of Octave Pedals Are The Best?

There are several types of octave effects to choose from, pure octave pedals, bass octave pedals, sub octave pedals and octave up expression pedal models with true bypass are some popular types. Monophonic octave pedals are often used by bass guitar players. Octave pedals generally increase or decrease your tones octave by one or two octaves.

Polyphonic Octave Pedal

A polyphonic octave pedal is unique in that it is capable of tracking guitar chords as well as single notes. The algorithms used in these modern octave pedals have almost eliminated the latency older analog pedals can suffer from.

Monophonic Octave Pedal

Monophonic octave pedals are a fan favourite with bassists. This is because they are perfect for recreating that ‘phat’ tone produced by synth basses.

Why Choose An Octave Pedal?

From guitar to bass pedal models, the best octave pedals exist to do a very specific job. In order for an octave pedal to reach its true potential the guitarist has to understand that many other aspects have to be spot on.

Octave pedals aren’t the most popular modulation pedal on the market for sure. But they do provide the ability to manipulate your signal subtly or into something entirely different.

Although by no means essential, an octave pedal certainly provides a fun and interesting way to change your sound, increase your musical range and try new things.

Enjoy our collection of the best octave pedals on the market. Hopefully you’ll find the one that’s right for you.

Catalinbread Octapussy Octave & Fuzz Pedal

Catalinbread Octapussy Octave & Fuzz Pedal

  • ✔ Features Attn(Attenuate), Gain & Body Control Knobs
  • ✔ Based On An Old Classic Circuit
  • ✔ Durable Metal Chassis
  • ✔ Beautiful Pedal Design
The Catalinbread Octapussy modern octave fuzz pedal is a frisky take on an old classic octave fuzz, huge range and blooming sonic textures.
  • Since Octapussy is expressly designed to be interactive with your guitar’s controls, it should best be placed as early in the signal chain as possible, preferably right after your guitar and definitely not after any buffered pedal.
  • Fuzz pedals are great stacked after the Octapussy. The Octapussy will match up great with the fuzz and cut right through it.
  • Amp-style overdrives should definitely be placed after the Octapussy. The Octapussy into the DLS MkII is an amazing combination.
  • Octapussy can run on 9volts DC all the way up to 18volts DC.
  • Play sweet, breathy, delicate octave-up melodies up high on the neck.
  • Play epic soaring leads that are full sounding with upper harmonics that bloom and bloom as you hold that bend.
  • Get tough sounding almost ring modulated double-stops that growl when you sustain it.
  • Obtain sounds that evoke Caribbean steel drums.
  • Riff out with a textured, harmonically rich fuzz tone that can achieve cello/sax-like qualities.
  • Achieve mysterious sounding droning melodies.

The Octapussy is essentially, an octave-up fuzz in the tradition of the Octavia. But it’s not a clone of that circuit! Nope, it’s an original circuit utilizing 3 silicon transistors and two diodes that takes the tradition to the next level! The preamp section is custom voiced to give you an extremely dynamic playing response. You’ll get those famous high-octave lead tones up high on the guitar neck but you’ll also get an amazing array of fuzz tones anywhere else on the neck – just by how you play it and how your guitar’s volume, tone, and pickup selector is set.

The more you play the Octapussy, the more sounds you’ll find in it!

  • Gain – This control increases the gain for more fuzz, harmonics, and upper-midrange frequency boost. it is voiced to be usable throughout its range from minimum all the way to maximum.
  • Attenuate – This control should normally be set full counter-clockwise. For best tone and response, only attenuate where you’ve got the Gain and Body knobs really cranking and need to reduce the output some.
  • Body – This control increases the bass response or ‘thump’ frequencies. like the Gain knob, it also increases output and harmonic content. Technically, it is a negative-feedback loop with variable frequency response. But let’s not dwell on technicals. ..this is another more knob!

The Catalinbread Octapussy modern octave fuzz pedal is one of the most dynamic, responsive octave up fuzz we’ve seen. It has great note bloom and sustain. The Octapussy doesn’t choke your notes off like some budget octave fuzz pedals. Depending upon where the knobs are set on both the pedal as well as the volume knob and pickup selection on your guitar this one does everything you want. From octavia styled leads to think power chord riffs. We can’t recommend this octave fuzz pedal enough!

Catalinbread Perseus Sub-Octave Fuzz Pedal

Catalinbread Perseus Sub-Octave Fuzz Pedal

  • ✔ Toggle Switch - Choose Between 1 Or 2 Octaves Down
  • ✔ Features Volume, Cut & Blend Control Knobs
  • ✔ Tracks Anywhere On The Neck
  • ✔ True Bypass Switching
The Catalinbread Perseus sub-octave fuzz guitar effects pedal is so massive and thundering, you’ll regret turning it off. Called Perseus due to the lowest note in the universe coming from the Perseus cluster.

 

Catalinbread believe the Perseus is the coolest analog octave-down fuzz out there! The Perseus is an octave-down fuzz that allows you to select either one or two octaves down mixed with a fuzz sound that you can blend to any mix of the two you want, including just the fuzz or just the sub-octave. The Perseus can track the sub-octave note accurately no matter where on the neck you are playing!

The Perseus features three knobs and an octave switch. While the controls on the Perseus may seem simple, it’s important to know that your guitar’s tone, volume and pickup selection makes a big difference in the Perseus’ behavior.

  • Volume – You’ll notice that Perseus has plenty of outpute so you can pummel your amp to your heart’s desire. Unity volume is around 10:00.
  • Cut – It reduces the bass content of your signal. This allows you to use the Perseus into a cranked, overdriven amp without ‘flubbing’ out from too much bass as well as creating cool textures for lead playing.
  • Blend – This control allows you to mix the fuzz and octave sounds in any amount you want.
  • Octave Switch – This switch allows you to switch between one or two octaves down.

Some words from the lead designer of the Perseus pedal.

“I’ve always liked the idea of analog octave down pedals. But most of them don’t track well on the low strings and some of them don’t have enough output or any control over the output volume at all. Of course, with the new offerings in the digital realm, we now have pedals that will track perfectly and even polyphonically to boot! The digital pedals are way cool, but I was still hankering for somethiing funky, greasy, fuzzy. ..unpredictable, if I want it to be. So I got out the breadboard and started working.”

Oh, and why is this pedal called Perseus?

“The lowest note in the universe is coming from a black hole in the Perseus Cluster, about two hundred fifty million light yeras away. What’s happening out there is that intergalactic gas has concentrated around a cluster of galazies, forming a cloud. A massive black hole is sending out jets of particles that crash into the cloud, causing pressure waves to ripple outward. Some astronomers interpret these as sound waves. of course, even if you call it sound, it’s too low for anyone to hear. They estimate the note to be a ‘B flat’, about fifty-seven octaves lower than middle C.”

“Ok, no, the Perseus won’t give you 57 octaves below middle C, but it will give you a measly one or two octaves!”

-Howard Gee, Catalinbread

Overall, if you play lead, this is a great pedal with a very unique sound. It’s durable, well made, and with its own noise gate system inside, it’s as quiet as a mouse until you come to play something. For something other than your usual ‘octave up’ pedal, give the Perseus a try.

Featuring our superb next generation octave-engine and individual blend controls for dry, octave-up and two sub-octaves, SUB ‘N’ UP is set to deliver flawless octave tones whether you’re playing complex chords or groovy single-note lines. And with the option of adding modulation to the mix via our high-powered TonePrint editor, for spacey ambient octaves, SUB ‘N’ UP OCTAVER truly is the definition of pitch perfection.

Download the free TonePrint app for Android and iPhone, choose the TonePrint you want to hear and beam it instantly from your phone through your guitar’s pickup into your TonePrint pedal. No cables needed.

Overall our impression of this pedal has been positive. It can produce notes one octave above, and one and two octaves below the input signal. The controls initially appear quite simple: level controls for each of the added octave sounds, and one to adjust the level of the original signal. There’s also a 3-way toggle switch, to choose between polyphonic mode, monophonic mode and Toneprint mode.

Toneprint is a game changer, it not only lets you send custom made tones to the pedal via the app but you can actually control subtle settings for each of the additional octaves. So you could increase the gain on the higher octaves but leave it alone on the two lower octaves. The app really does open up the configuration of this pedal to levels far greater than the onboard control knobs can.

A great pedal, with great sounds and lots of customization. Win, win win!

Electro-Harmonix Octave Multiplexer Pedal

Electro-Harmonix Octave Multiplexer Pedal

  • ✔ Easily Generate Deep Bass Tones
  • ✔ Monophonic Device - Works Only On Single Tones
  • ✔ True Bypass Switching
  • ✔ Durable Metal Chassis
The Electro-Harmonix Octave Multiplexer guitar effects pedal generates deep, phat bass tones one octave below the notes you play.
Be Advised - Possibly Low Stock
Buy From Amazon.com
  • 1/4″ input, dry output and effect output
  • DC power input for battery replacement
  • Status LED – pedal engaged or bypassed

Get down! Generates deep, phat bass tones one octave below the notes you play. Two separate smoothing filters enable you to tailor your sub-octave signal to the exact bass sound you desire, separating the Octave Multiplexer from other octave devices. Run your vocals through it and sound just like Ike Turner. This is a monophonic device and works only on single notes.

  • HIGH FILTER Knob – Adjusts a filter that will shape the tone of the sub-octave’s higher order harmonics. Turning the HIGH FILTER knob clockwise will make the sub-octave sound more gnarly and fuzzy.
  • BLEND Knob – This is a wet/dry knob. Counter-clockwise is 100% dry. Clockwise is 100% wet.
  • BASS FILTER Knob – Adjusts a filter that will shape the tone of the sub-octave’s fundamental and lower order harmonics. Turning the BASS FILTER knob counter-clockwise will make the sub-octave sound deeper and bassier. Please Note: the BASS FILTER knob is only active when the SUB switch is set to ON.
  • SUB Switch – Switches the Bass Filter in and out. When SUB is set to ON the Bass Filter and its corresponding knob are activated. When the SUB switch is set to OFF, only the High Filter is active. Turning the SUB switch on gives the sub-octave a deeper, bassier sound.

This is a very well made pedal, all metal, metal switch, etc. The only plastic is the knobs and they seem pretty solid as well. It does what it’s capable of doing (considering it’s monophonic limitations) very well. If you’re looking for something that will track multiple, complex chords and notes at the same time then this isn’t the pedal for you. If you want a solid octave pedal that is professionally made (exactly what we’ve come to expect from Electro Harmonix) then give this pedal a try!
