I use this on my bass, and I'm not sure how suited it is to the lower frequencies of the bass.

I did let my cousin use it in his guitar rig, and he loved it and I loved the tone of it too. The split effect out means that you can send your effected signal to a bass rig, and hence not ruin your expensive guitar amp.

It does work with the bass, it just sounds too muddy on when you get down past the E on the A string, as it is only an octave down.

I purchaced this pedal to allow me to play a decent sounding bass line as well as a lead part and it does this quite well i take the output from the lower octave and feed into a bass amp, while not perfect it copes suprising ly well yes there are a few "wobbles" where it seems to struggle but i think that could be lessend by spending more time fine tuninig. overall does what it says on the tin and well worth the money you want perfection then you'll have to pay a heck of a lot more!

This made my jazz guitar sound apst like a double bass and added a new sound when soloing with the octave blend. Got this as one review said it is analog and it does have a thick sound. This I preferred to the YouTube clips of the micro pog which I understand is digital and a thin sound

Works great with my Jazz Bass rig 5 May 2010
By Matty D - Published on Amazon.com
This is a great little pedal I recently picked up. I use it with my bass rig and a couple other pedals in my chain, and I have to say it really holds its own.

While this pedal just does the sub-octave, that is what I need it for. You can EQ your octave sound to go from very clean and bassy to gritty and grumbly. The blend knob is really essential with all bass pedals, and that's no different here. It's really easy to dial in the sound that you're going for. I find these knobs particularly good for foot-use, so it's pretty easy to make on-the-fly adjustments with your toes, if that's your thing. It's got true-bypass, which is always* a plus. This pedal sounds great followed up with nice overdrive too.

Keep in mind if you get this pedal that it is monophonic. It uses audio tracking to produce the sub-octave sound. If you are playing chords, or octaves, or power chords, or anything else polyphonic, you'll get a little weirdness. The tracking will catch one note, and then the other. Sometimes, it can even sound kind of cool, but there's really no way of controlling it, and it's probably not what you're going for. With bass, I find that the same effect can be produced on the low string(s) of you bass, so just be aware of that.

So yeah. If you're looking to beef up your sound a little, this is a nice cheap option that will really push the subs.

Octave Down, Single Notes, Volume Good 20 Jan. 2013
By Guiness St. James - Published on Amazon.com
Verified Purchase
My first octave pedal was a Clone of a Foxx Tone Machine. It had a fuzz circuit that was ok, the octave tracked well and could
even handle more than one note within reason. A solid performer, but a little weak on signal and fuzz quality.

Next I tried a Joyo Voodoo Octave. I really liked how smoothly the fuzz and octave worked together, more modern than old school
sounding and the signal level was good. However, the octave was UP one and to me it sounded too thin for what I was going for, but it did track chords well. I did like this pedal very much, but I wanted the buzzy bottom of an octave down ala Rory Gallagher on "The Loop" and "When My Baby She Left Me" (Check those tracks to see what the EHX sounds like.)...

The Electro-Harmonix is a standalone DOWN one octave pedal. It's thicker sounding than either of the other two, but mainly tracks
single notes only. Any chords or arpeggios will muddy up and the tracking will flutter.
But on those single lines it tracks very well and gives you anything from a light doubling octave down, to a spaced out
synth-like old-school video game like sound.
Not something you would use all the time, but every so often for cool Rory Gallagher to Jack White style effects, especially with some fuzz.

Like any modulating effect, you have to experiment with it's placement in your chain.
If it sounds weak, switch it to before or after boost/distortion pedals. In my chain it works perfectly BEFORE my boost pedals.
When I stomp it on, the level is consistent.
And keep in mind, as with any octave down pedal, the less dry signal more wet signal you dial in, the less top end you get.
You are after all then hearing the dub octave down more.
Love it.

Very Versatile Pedal! 13 Jan. 2014
By Todd A. Hooper - Published on Amazon.com
Verified Purchase
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 works well with other pedals and doesn't seem to alter my tone in a bad at all when not in use. I use this pedal on my "acoustic" pedal board to record bass lines with my looper to jam over. I turn the hi octave filter up to full cutting that and just use the low octave, I don't use the sub as it gets really low, but with my acoustic guitar I can lay down some really "believable" bass lines. It's also cool to use in the other direction cutting the lows and using it with some OD for a Hendrixy octave type thing. It's def a one note at a time type of pedal, doesn't do multiple notes well at all unless you just want to go crazy with it. It's a great sounding pedal and with the addition of overdrive and even by flipping on the sub octave switch you can get some really crazy tones out of it as well. I have not run it stereo so I can't comment on that.
Great Analog Octave Pedal 6 July 2013
By zilla b - Published on Amazon.com

I play six-string bass strung like a guitar octave lower (E to E). My style combine classical guitar and funk bass techniques. This monophonic device tracks excellently with proper right-hand rest strokes. I love being able to use guitar fingerings higher on the neck without loosing the low end. I generally stay above the 7th fret when using this pedal. Lower on the neck there are a few dead spots and sound gets muddy.
I Iike having both a low and high filter to tailor the suboctave sound but the controls are not intuitive. The "bass" knob responds like a high-pass filter and the "treble" responds like a low-pass filter. I'm not sure the point of turning the suboctave switch off other than to turn it into a from of distortion. Another distortion is always useful in the studio, but Ibuy pedals I don't have to bend-over and adjust live.
Greatest sounding pedal for the price, I never cared about a second lower octave so this pedal a great workhorse for any bass player that plays higher on the neck.
A great octave pedal with amazing tone control. 21 April 2013
By Mike IronFist - Published on Amazon.com

This pedal is just fantastic. I use it with my bass when I need to do a heavier rhythm section. I just play much higher on the neck and use the pedal to add that bassy sound back in.

The high and low filter knobs really give you a lot of control over the sub-octave's tone and they let you shape the sound exactly as you'd need it.
I recommend cranking up the bass filter all the way before you do anything with the high filter. The high-filter affects the high-end growl but the bass filter gives the sub-octave its power and punch.

The blend knob is a little bit biased towards the sub-octave, so you really have to adjust it carefully to get the right mix of your original signal and the sub, but that's a minor issue and more of a feature than a glitch. It's still possible to get more subtle sub-octave effects, you just have to be careful with the knob.

By all means, if you're looking for a fair-priced octave/octavider pedal that sounds good, this is the one I'd recommend.
