Description
Overview
The Electro-Harmonix Octavix Octave Up Fuzz delivers the definitive late 1960s fuzzed-out, octave-up sound, blending vintage psychedelic tones with modern enhancements. Designed to capture the essence of classic octave fuzz, this pedal allows guitarists to add a thick layer of distortion and a shimmering octave above the fundamental note, creating a rich, harmonically dense texture.
Housed in EHX’s rugged nano package, the Octavix is built for the road while maintaining a period-evocative design. It offers versatile power options that fundamentally change the character of the fuzz, allowing players to choose between a vintage “sag” or a modern, tight response.
Key Details
- Dual Voltage Rails: A mini-toggle switch allows you to select between 9V and 24V power. At 9V, the pedal behaves like a classic, saggy fuzz box; at 24V, it delivers a tighter sound and a richer, more pronounced octave tone.
- Precision Controls:
- Volume: Regulates the overall output level of the pedal.
- Boost: Controls the amount of fuzztone saturation and gain.
- Octave: Adjusts the volume and presence of the octave-up effect.
- Signal Integrity: Equipped with True Bypass switching to ensure your dry signal remains pure when the effect is disengaged.
- Visual Feedback: Features a bright blue LED indicator and a psychedelic aesthetic that pays homage to the era of its sonic inspiration.
Use Cases
- Psychedelic Rock: Perfect for recreating the swirling, distorted textures of the late 60s.
- Lead Guitar Highlights: Use the 24V setting for a tighter, more defined octave lead tone that cuts through a dense mix.
- Lo-Fi Textures: Switch to 9V to achieve a “saggy,” compressed fuzz sound ideal for experimental or garage rock styles.
- Sonic Layering: Blend the octave volume to create the illusion of two guitarists playing in unison.
Installation
The Octavix is a stompbox pedal designed for easy integration into any guitar signal chain. Simply connect your instrument to the input and your amplifier or further effects to the output. The pedal can be powered via the included 9V battery or a standard 9V DC power supply. Use the mini-toggle switch to select your desired voltage rail (9V or 24V) before engaging the pedal to set your preferred tonal character.

- Instrument Support: Compatible with electric guitars and other mono-signal instruments.
- Power Requirements: Supports 9V battery or external DC power.
