Project Overview

This is the Kheiron Klon project, a Klon Centaur on steroids that teaches you how different parts of the circuit work.

We compiled every possible mod on this classic circuit and designed a board that allows you to switch between stock and modded versions. In some cases, you can even choose to use a fixed resistor or a trimpot to set the amount of resistance you want.

Kheiron Klon is both ideal for beginners and advanced builders who want to dig deeper into how pedal works and modding.

Introduction:

Kheiron Klon is inspired by the legendary Klon Centaur, one of the most highly regarded and in-demand effect pedals ever created. Appreciated for its creamy overdrive, it’s also used as a Clean Boost for warming up the signal. This ground-breaking transparent overdrive circuit adds gain to your signal without significantly altering the guitar’s tone.

The introduction of the Klon back in the early to mid ′90s is arguably one of the most relevant events in the history of overdrive pedals. Its use by such players as John Mayer, Nels Cline, and Joe Perry (to name just a few) and its scarcity on the used market have propelled prices to unparalleled levels, giving it the title of the most expensive pedal in the world.

In PCB Guitar Mania decided to praise the original and created this unique version that allows you to choose, experiment, and learn from a board that gathers every conceivable mod. In this document, you will find a description of the different switches’ positions, the section they affect, and the overall tone resultant.

Are you ready to add this mythological board to your collection?
