Hammertone Limited Edition

The MOSFET-based Black Eye Boost is back for the first time in over a decade. A clean boost that adds just a splash of colour to your tone in all the right ways, the Black Eye Boost doubles as a powerful buffer and is the perfect secret weapon to add to the end of your chain.⁠

This all discrete, MOSFET based circuit provides nearly 30db of unadulterated clean gain boost with a minimum amount of tone coloration. Note that you can also use this as an attenuator by turning the Boost knob counterclockwise away from the noon position.

It can also be used as a powerful buffer with an input impedance of around 5 MOhms and an output of around 1 kOhm, best used after your effects chain. This device does not create distortion or overdrive on its own. However, it can be used to drive your favorite amp or pedal into singing distorted sustain. Simple, yet effective.

Top notch components and circuit design assure that your signal arrives to its destination in a truly pure state. Black Eye is true bypass and built one at a time by human beans on the shore front of Akron, Ohio.

Switching This device uses mechanical true bypass switching.
