Key Features
- Up to 30 dB of clean boost with minimal tone coloration
- Discrete MOSFET circuit preserves dynamics and clarity
- Functions as boost, attenuator, or high-quality buffer
- Limited edition build with true bypass switching
EarthQuaker Devices Black Eye Boost Limited Edition Overview
The EarthQuaker Devices Black Eye Boost Limited Edition is a straightforward yet powerful tool for players who want pure, uncoloured gain. Built around an all-discrete, MOSFET-based circuit, it delivers up to nearly 30 dB of clean boost without altering the natural character of your guitar or signal chain. It’s designed to enhance what’s already there, rather than impose its own sound.
With a single Boost control, the Black Eye is easy to dial in and surprisingly versatile. Turn the knob clockwise for transparent level increase, or roll it back below noon to use it as an attenuator. It also works as a high-quality buffer when placed after your effects, helping maintain clarity over longer cable runs. Handbuilt in limited numbers, this pedal focuses on reliability, purity, and simplicity.

Full Description
View Full DescriptionPure clean boost performance
The Black Eye Boost is designed to deliver clean gain with absolute transparency. Its discrete MOSFET circuit provides up to nearly 30 dB of boost while preserving the original tone, feel, and dynamics of your instrument. There’s no added grit, compression, or EQ shaping, making it ideal for players who want their guitar and amp to remain the stars of the signal chain. Whether you’re lifting your volume for solos or compensating for signal loss, the boost stays articulate and natural at every setting.
Flexible boost and attenuation control
Despite its simple single-knob layout, the Black Eye is more flexible than it first appears. Turning the Boost control clockwise increases output level, while turning it counterclockwise past the noon position allows the pedal to function as an attenuator. This makes it useful not only for boosting solos, but also for managing overall signal level in complex rigs. The intuitive control encourages experimentation and makes it easy to adapt the pedal to different guitars, amps, and playing situations.
High-quality buffering capability
In addition to boosting, the Black Eye can serve as a powerful buffer when placed at the end of your effects chain. With an input impedance of around 5 MOhms and a low output impedance of roughly 1 kOhm, it helps preserve high-end detail and signal strength over long cable runs. This makes it especially useful on pedalboards with multiple true bypass pedals, ensuring your tone arrives at the amp clear, focused, and intact.
Handbuilt reliability and true bypass
Every Black Eye Boost is built one at a time using top-quality components and careful circuit design. Mechanical true bypass switching ensures your signal remains untouched when the pedal is off. The limited edition construction adds a touch of exclusivity, while the robust build quality makes it ready for regular gigging and studio use. Simple, dependable, and thoughtfully made, it’s a pedal designed to disappear sonically while making your rig work harder.
