Electro-Harmonix Octavix


In an effort to both recreate and modernize a classic sound from the 60’s, the team at EHX have put together an aggressive little machine that can broaden your range of fuzz tones. Although this pedal does sound killer on guitar, some of its bite and octaving capabilities are not easily heard when used by a horn player

HornFX Review

Interface:  3.5/5
The controls are incredibly simple and easy to understand. Sadly, the octave knob’s effect seems thoroughly limited.

Versatility: 2/5
This pedal seems as though it can do a lot, but that does not translate well to horns. Firstly, the added octave does not speak clearly, if at all. This leaves you with a plain fuzz pedal that is fairly limited.

Live application: 2/5
Although this pedal’s fuzz does have a warm quality to it, it begins to break up your sound very quickly. That breakup can be heavily detrimental to the integrity of your sound and tone at points.

Tone Reproduction: 2/5
The fuzz tone can be warm at times, but can also break up to an extreme level. The tonal quality is hard to ascertain because of the intensity of the fuzz at certain settings.

Product Information

Octavix delivers the definitive late 1960’s fuzzed out, octave up sound together with modern enhancements that update the classic concept.

Housed in EHX’s rugged nano package, the Octavix features Volume, Boost and Octave knobs. Volume regulates the output level of the pedal. Boost controls the amount of fuzz and Octave adjusts the volume of the octave above. A mini-toggle lets the player select between 9 or 24 volt power rails and determines the power supply voltage for the entire circuit. At 9V the pedals behaves like the classic, saggy fuzz box. At 24V the Octavix delivers a tighter sound and a richer octave tone. True bypass ensures maximum signal path integrity.

A period-evocative, psychedelic design and blue LED contribute to the pedal’s vintage vibe. Octavix runs on a 9 volt battery or accepts a standard EHX9.6DC power supply.
