Heads up Builders widely report inconsistent quality from PCB Guitar Mania boards, and whether a given board works is a gamble. Read recent forum reports before ordering.

From the vendor

Project overview:

Incantation conjures an immense display of overdrive tones, perhaps more than you’re used to. Subtle and complex or filthy and crunchy, playing blues or rock, this board fits the bill for anything you’d want to play. Become the wizard of all the overdrive soundings!

Introduction

There is a secret invoking ritual that will grant you all the overdrive tones you were looking for. You will not need to draw a pentagram on your living room floor or set your best amp on fire under the moonlight. The secret formula is much simpler and effective: build your own Incantation pedal, plug it in and enjoy a myriad of unprecedented tones.

The circuit of Incantation has an amp-like circuit architecture, with multiple cascaded MOSFET and JFET gain stages to guarantee the most natural, touch-sensitive overdrive conditions possible and a seemingly endless range of clean-up with your guitar’s volume knob. From smoothly fingerpicked melodic phrases to striking riffs and everything in between, Incantation will grant you all.
