From the vendor

Project overview

A versatile overdrive/distortion pedal inspired by The Quantum Mystic from Black Arts Toneworks that has, in turn, roots on DOD 250’s classic circuit. Play everything with it: blues, classic rock, dream pop, total doom annihilation, and furthermore!

Introduction

Black Mystic is an opamp-based distortion/OD featuring a 3 band active EQ and germanium clipping. If you are a stoner (and or a) doom player, this versatile pedal is for you.

Heavily inspired by the legendary DOD Overdrive Preamp 250 pedal. The Black Mystic will give you that old-school-like sound thanks to the active Eq ability to cut frequencies. Also, use the EQ to boost the final gain stage to go into modern, heavily saturated, distorted tones. You can dial back the distortion, increase the volume and use the active EQ to find transparent boost tones.

There are plenty of features to find and hours to devote to this multifaceted pedal!
