From the vendor

Project overview

Inspired by the EQD’s Organizer, this divine pedal can create huge church organ tones for your guitar. Not every day I can write about a circuit designed to deliver the sound of an old church organ crossed with the funky MCI Guitorgan that even allows and encourages you to come up with sonic colors all your own.

Introduction

Within the 6-knob layout, you have control over octave up, octave down, and a choir control for blending in two octaves up and down. The Lag dial provides changeable control over delaying the effect’s entrance, and an immediate control blends your straight guitar signal back in. Also, the high-quality analog/ DSP circuit retains an ‘Organic’ sound in your rig. One glance at the intuitively labeled controls lets you know exactly what you need to do to add in high-end shimmer, low-octave rumble, or a bit of delay for ambiance.

I could say many things about this pedal’s hypnotic and divine soundscapes, but good sounds speak louder than words, so I genuinely recommend trying this board. Now, you must excuse me; I will be in my chambers playing some organ-like waves for the next couple of hours.
