Octave pedals are some of the most fun pedals you can have on your board. Most guitar players probably think of them as a special effect for riffs or lead parts, but there is actually much more you can do with one.
In this post, I want to show you how to use an octave pedal in five creative ways. Some of these are genuinely useful in a band mix, while others are more about having fun and getting inspired to play differently. Either way, that is part of what makes an octave pedal worth having around.
For this article, I used the Mooer Tender Octaver, which is a very compact pedal with controls for dry signal, upper octave, and sub octave. It also has three different modes called Fat, Tight, and Swell. Even though the examples here were done with that pedal, the same general ideas apply to many other octave pedals as well.
My signal chain for these examples was fairly simple: Telecaster into my pedalboard, then into an Uraltone Jr, Two Notes Torpedo Live, and a Mesa Boogie Rectifier 4×12 impulse response.
1. Add a little upper octave for extra shimmer
The first way to use an octave pedal is also one of the most subtle.
Instead of going for an obvious effect sound, try blending in just a little bit of upper octave on top of your dry guitar signal. When set carefully, it does not scream “octave pedal” at all. Instead, it adds a bit of shimmer, richness, and width to your clean or edge-of-breakup tone.
This kind of setting works especially well if you are the only guitar player in the band. If there is no keyboard player either, adding a touch of upper octave can help fill more of the frequency spectrum without making your part feel overplayed.
It is one of those things that may not sound dramatic on its own, but the moment you switch it off, your tone feels a little smaller and less exciting.
2. Make your lead guitar sound bigger
Another very practical way to use an octave pedal is to make lead parts sound larger.
For this kind of sound, I like blending in a little upper octave and a little sub octave with the dry signal still present. The result is a more dramatic and wider lead tone that can work very well with delay and reverb-heavy ambient sounds.
On its own, this kind of octave blend can sound slightly exaggerated. In context, though, it can be exactly what a lead part needs to feel bigger and more cinematic.
If you do not want that much drama, another option is to keep only a little sub octave underneath the lead line. That does not change the character of the part as much, but it adds some weight and authority. Again, this is especially useful if you are the only guitarist in the band and want your lead part to fill more space.
3. Kill the dry signal for high octave lines
This is where things start getting really fun.
If you remove the dry signal completely and keep only the upper octave, you can get a very different kind of sound. It becomes thinner, more delicate, and more atmospheric. Played high up the neck with plenty of delay and reverb, it can create a very pretty intro sound or a nice ambient melody line.
This type of octave pedal sound is not something you would use all the time, but it can be incredibly effective in the right musical setting. It also forces you to play differently, which is often a good thing.
Sometimes a pedal earns its place on the board not because you use it on every song, but because it gives you access to sounds that inspire new ideas.
4. Add sub octave to single-note riffs
This is probably the most obvious octave pedal trick, but it is still worth mentioning because it works so well.
If you play a single-note riff and blend in some sub octave, the riff immediately sounds thicker, meaner, and more powerful. It is a great way to add some extra oomph without reaching for a completely different rig.
If you have ever heard a Jack White-style riff and wondered why it sounds so massive, there is a good chance some sort of octave effect was part of the recipe.
This use of an octave pedal is simple, effective, and just plain fun. Sometimes that is all the justification a pedal needs.
5. Fake an organ with your guitar
One of my favorite weird uses for an octave pedal is turning the guitar into a fake organ.
If you remove the dry signal and blend in both the upper and lower octaves, especially with some delay and reverb, the result can become surprisingly organ-like. Switching to a swell-style mode can make that effect even stronger.
This is not going to fool anyone into thinking there is a real Hammond in the room, but it can absolutely create that kind of pad-like or church-organ-inspired texture that fills space in a very musical way.
And if you want to push it even further, add some overdrive and tighter tracking and you can get into a much more aggressive rock organ territory as well.
This is one of those sounds that reminds you how creative guitar pedals can be when you stop thinking of them only in the most traditional way.
Bonus: replace your bass player too
This one is only half serious, but only half.
If you kill the dry signal, remove the upper octave, and bring in a lot of sub octave, you can get something that behaves a bit like a bass guitar. It is obviously not the same as having a real bassist, but it can still be useful for writing, layering, or messing around with arrangement ideas.
Interestingly, with the Mooer Tender Octaver, the tracking is a little slow in this kind of setting. In a funny way, that can actually make the result feel like one of those bass players who always plays slightly behind the beat.
So no, I am not seriously suggesting you fire your bassist. But as a creative tool, this kind of setting is a lot of fun.
Final Thoughts
If there is one thing this experiment reminded me of, it is that octave pedals are much more versatile than many guitar players give them credit for.
Yes, you can use one for the obvious riff stuff. But you can also use an octave pedal to add shimmer, make lead parts sound bigger, create high ambient melodies, fake organ-style textures, or even come up with bass-like lines for demos.
That is why I think every guitarist should try having an octave pedal on the board at some point. You may not end up using it on every song, but it is a brilliant tool for inspiration. And sometimes that is exactly what a pedal should be.
An octave pedal may not be the most essential effect in the world, but it might be one of the most fun.
