From the vendor

Project overview

Experience the sweetest of sounds with this low gain overdrive inspired by ThorpyFX Peacekeeper. This pedal is great to boost your dirty amplifier or as a pure overdrive that sits on the edge of crunch.

Introduction

Pacifier is a board designed to suit all guitars and all amps while delivering the sweetest on the edge of crunch tones out there. With the pre-gain set low and the volume pushed, you get some beautiful clean boosts that can push your already driven amp up. You can also use this pedal with a bit of extra pre-gain to start pushing the amplifier with a soft, almost driven sound that sounds beautiful for softer rock styles and blues.

The Pacifier design has unique features, like the midrange control before the pre-gain section giving you a much sharper and defined control of your tone.

The high and low EQ controls are part of an active stack that sits after the pre-gain circuit. This gives these controls the widest range possible as you can go from entirely cut frequencies to heavily boosted tones that cut through the mix.

Now is time to sit on a comfy chair and wonder your audience (and why not yourself) with the most peaceful and relaxing sounds.
