From the vendor

Project overview

Inspired by the legendary EQD Tone Reaper a 3-knob tone bender with a hybrid silicon-germanium circuit that allows you to dial an array of tones from every bender version. It is also great for anyone looking for a high-gain style grind tone at its higher fuzz settings.

Introduction

The Reaper Device is a vintage-style fuzz device with a unique design in which the tone control has been modified into a BMP tone stack in addition to the pair of germanium transistors simplified into a single high gain silicon transistor MPSA18.

This silicon/germanium hybrid is ready to deliver an array of tones from every bender era with careful tweaking of the tone and fuzz controls. From light and spitty to a growling crunch, all with a midrange punch to make it scratch and kick through any mix. You will also get those higher gain Randy Rhodes style grind at its higher fuzz settings.
