Electro Harmonix Octave Multiplexer Review – Features,FAQ,Pros & Cons

Electro Harmonix Octave Multiplexer

How would you like it if you were able to boost the low monotones when playing your music? How about sounding more like Turner when singing? Well, you could easily do that if you had the Electro Harmonix octave multiplexer. You will be able to generate phat octave tones. Each one a level below the one you are playing. One thing you will have to keep in mind is to play a tone at a time. That is because the EHX octave multiplexer is designed to only modify one tone at a time.

This multiplexer is the best that I have so far used and it replaced a whammy pedal I used to play with in my early days of playing guitar. I find that it helps me to understand my music better by making me perform mono-tones. Playing monotones makes it easy to master each and every stroke I give my guitar. Besides,this multiplexer has two separate smoothing filters that enable you to get the exact bass sound you desire. It does that by tailoring the sub-octave signals.

Electro Harmonix Octave Multiplexer Vs Micro POG - Which Is Best?

If you cannot decode which one to buy between the octave multiplexer vs Micro POG, then here is what you need to know. The octave multiplexer is designed to generate sub-octaves for monotones only. You will however get the best bass as long as you keep to one tone at a time. The Micro POG is the one designed to be used top as a polyphonic octave generator. The Micro POG however does not give the natural sounding bass you get from the ehx octave multiplexer.

Generates Natural Sounding Octaves

This EHX octave generator is capable of producing the best phat bass tones below the notes you play. If you are a guitar lover, then you need this octave generator pedal. It will make a difference by making the note sound natural and heavy. It is therefore among the best octave generators when you need to record your music. Recorded music is judged harshly than a live performance. Therefore, getting the best natural sound from your tones is a must.

​High Filter Knob

high filter knob

​You use this knob to shape the each tone's higher order harmonics. If you need to make the sub-octaves gnarly and fuzzy, then you simply turn it in a clockwise direction. If you need to make the more crystal clear, then you simply turn is counter clockwise. The best setting to start with is when it dial marker is pointing to mid position. It basically filters out the high frequency harmonics from the notes you are playing. If you are aiming for a "Turner note," it is best you turn this knob counter clockwise.

​Blend Knob and Bass Filter

​The blend knob allows you to add a wet or dry effect to your tones. To get a dry effect on your tone, simply turn the blend knob counter-clockwise. To get the wet effect on your tones, you simply turn the knob clockwise. I prefer to go with dry tone effect when I want to get my "Turner tone." You can play around with this knob to get the best setting for your music. You can start with when the knob marker is at its point.

​SUB Switch

sub-switch

​This is the switch that you use to activate the bass functionality of this multiplexer. It switches the Bass Filter in and out. When you set it to ON, it turns on the Bass Filter feature as well as its corresponding filtering features. If you turn it off, only the High Filter will remain active. The SUB switch is the one you need to use to get the deeper “bassier” sound. I would recommend you start with the SUB Switch off, play a tune, and then turn it on. That way, you will be able to grasp its full effect.
