Walrus Audio Eons Black Five-State Fuzz
The Walrus Audio Eons is a versatile five-state fuzz pedal designed to offer a broad spectrum of saturated tones ranging from vintage textures to modern high-gain distortion. It features a unique voltage control that allows players to starve or boost the internal circuit for highly varied tactile responses.

Introduction
The Walrus Audio Eons Black Five-State Fuzz is a high-performance guitar effects pedal engineered to provide a comprehensive suite of fuzz sounds in a single enclosure. Recognised for its flexibility, the Eons functions as a multi-modal workstation, capable of driving amplifiers into varying degrees of saturation. It is positioned as a primary tool for guitarists who require both classic and experimental fuzz characteristics.
Five-State Clipping Architecture
The core of the Eons is its five-way rotary switch, which selects between different clipping modes. Each mode functions as a distinct fuzz circuit:
- Mode I: Silicon clipping for a traditional, compressed fuzz sound.
- Mode II: Silicon clipping with an added bass boost for a thicker low-end response.
- Mode III: Germanium clipping, providing a smoother, more vintage-inspired character.
- Mode IV: LED clipping diodes, offering a louder, more open and 'crunchy' fuzz sound.
- Mode V: Hard-clipping silicon combined with LED and Silicon soft-clipping for aggressive, high-gain textures.
These modes allow the pedal to mimic the behaviour of multiple historical fuzz units while maintaining a consistent control interface.

Variable Voltage Control
A defining feature of the Eons is its variable Voltage knob. This control allows users to adjust the internal operating voltage from a starved 3V up to a high-headroom 18V. Lower voltage settings result in 'sputtery' or 'gated' textures, where the note decays abruptly, popular in lo-fi and garage rock genres. Increasing the voltage expands the dynamic range and punch, providing a massive, open sound that reacts more linearly to the player's pick attack.
Sonic Character and Application
The sonic signature of the Eons is highly customisable. It can transition from smooth, singing sustain reminiscent of festival-era classic rock to 'unhinged' sonic chaos. Because the pedal reacts significantly to the guitar's volume knob and the player's touch, it is suitable for various genres including stoner rock, psychedelic blues, and modern alternative metal. The straightforward control set ensures that despite the complex internal circuitry, users can dial in specific tones rapidly.
Compatibility and Comparison
While the Eons serves as a foundational dirt pedal, it is frequently used alongside other utility pedals. For instance, pairing it with a Boss NS-2 Noise Suppressor can help manage the high-gain hiss inherent to aggressive fuzz settings. It also complements spatial effects like the Boss DD-3T Digital Delay or the Fender Hammertone Flanger. Compared to more traditional single-circuit fuzzes, the Eons offers significantly more versatility due to its multi-mode design and voltage starving capabilities.

Frequently asked questions
- What is the primary function of the Walrus Audio Eons?
- The Eons is a fuzz pedal designed to provide a wide range of distortion and saturation effects for electric guitarists. It uses five different clipping modes to offer textures ranging from vintage smoothness to modern high-gain aggression.
- How does the Voltage control affect the sound?
- The Voltage control adjusts the internal power from 3V to 18V. Lower settings create a 'starved' or gated sound with distinct sputter, while higher settings provide more headroom, clarity, and a louder output.
- How many clipping modes does the Eons have?
- The pedal features five selectable clipping modes. These modes use different combinations of Silicon, Germanium, and LED diodes to change the fundamental character and compression of the fuzz.
- Is the Eons suitable for vintage rock tones?
- Yes, particularly in its Germanium clipping mode (Mode III), the Eons can produce the smooth, warm sustain characteristic of classic 1960s and 70s rock. The voltage control can also be adjusted to mimic the sound of a dying battery in vintage circuits.
- Can the Eons produce modern high-gain sounds?
- Absolutely. Mode V and the higher voltage settings are specifically designed for aggressive, open, and punchy fuzz that can push an amplifier to its limits, suitable for modern heavy music styles.
- What power supply does the Walrus Audio Eons require?
- The Eons typically requires a standard 9V DC centre-negative power supply. The internal voltage adjustment to 18V is handled by the pedal's internal circuitry, so you should not plug an 18V adapter into the input.
- How does the Eons handle different guitar pickups?
- The pedal is highly expressive and reacts brilliantly to different guitar setups. Whether using single-coils like those on a Fender Stratocaster or high-output humbuckers, the Eons maintains its distinct character while responding to the input signal's strength.
- Does this pedal feature a gated fuzz sound?
- Yes, by turning the Voltage control down toward the 3V setting, the circuit becomes 'starved.' This creates a gated effect where the signal cuts off quickly, producing a velcro-like or sputtery texture.
- What is the typical price for the Walrus Audio Eons?
- The typical retail price for the Walrus Audio Eons Black Five-State Fuzz is approximately £205. Prices may vary slightly depending on the retailer and current market conditions.
- Can I use the Eons with other pedals like a delay or chorus?
- Yes, the Eons works well in a signal chain. It can be paired with a Behringer UC200 Ultra Chorus for thick textures or a Boss DD-3T Digital Delay for lead lines, though it is usually placed near the beginning of the chain.
- What are the physical dimensions and build quality like?
- Walrus Audio pedals are known for robust build quality, featuring a sturdy metal enclosure and high-quality switches. The Eons Black edition features a specific aesthetic design typical of the brand's boutique styling.
- Does the Eons include a noise gate?
- While it does not have a dedicated noise gate circuit, the 'starve' function on the Voltage knob can act similarly to a gate by cutting off low-level noise when you aren't playing. For full noise suppression, a Boss NS-2 is a recommended companion.
