Mongol Device

Project overview

Inspired by the popular EQD BOWS pedal, a simple but powerful preamp/booster circuit built around a rare germanium transistor, delivering a rich, harmonic overdrive with tons of character. The single gain knob and two-position switch are like adjusting the tension on the bowstring, allowing you to fine-tune your sound and hit the bullseye every time.

Build the Mongol Device, and you’ll be riding the steppes of sound in no time!

Introduction

The Mongol Device is an easy-to-build, straightforward preamp/booster pedal with just one knob and a two-position switch. With two different modes, Full and Treble, you have the flexibility to shape your tone to your liking.

In Full mode, you’ll get a rich and warm sound with plenty of body and low end. Meanwhile, Treble mode is a resonant booster that can add a biting edge to your sound. With a “cocked wah” tone, it can drive any tube amp into a realm of harmonic-rich distortion.

If you use the Mongol Device with a drive pedal in front of it, the possibilities are endless. In Full mode, your dirt signal will turn into a powerful wall of sonic chaos. In Treble mode, you’ll have the ultimate lead tone at your fingertips.

So assemble your own Mongol Device, join the horde, and embark on a quest to conquer new musical frontiers!
