From the vendor

Project overview

Based on JHS Haunting Mids, this simple, yet extremely sound-defining pedal is a highly versatile tool able to switch up your sound. Metal players will love it for the added sharpness, while blues players can reduce the mids to let highs and lows shine through for sweet leads.

Introduction

You dreamed of a boost that allows you to cut through the rest of the band even when using different amps here and there or when using different sounds in one show? The JHS haunting Mids is a parametric mid eq and a boost pedal in one small beginner-friendly format. It allows you to dial in the mid-frequency you are looking for, the amount of it compared to the dry signal, and even allows quite a lot of extra volume. No wonder that this pedal that used to be a limited version now got its fixed place in the row of stomp boxes Josh Scott is selling. What else could you want?

This circuit allows you to achieve a +15db boost or scoop. The Lo/Hi toggle selects a broad or narrow bell curve. Continuously sweepable midrange center (400Hz–7.5kHz).
