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
King Centaur combines the Klon Centaur with the best one-half of the Knight of Tone circuit, giving you two great transparent overdrives in one. We added an order switch that allows you to stack them as you like, so prepare to have a lot of fun with it.
Introduction
This unique PCB Guitar Mania design allows you to stack, in the order you desire, the Klon Centaur with one-half of the Knight of Tone circuit to create the ultimate dual transparent overdrive.
The Knight of Tone section has a dual voltage capability that lets it be fed on 9v or 18v through an internal potentiometer. Important: NEVER SET BOTH SWITCHES ON -UP POSITION AT THE SAME TIME.
When we first tried this mix, we expected something good, but boy, let me tell you: both circuits stack amazingly and deliver a thick transparent overdrive that surpassed our expectations!
