Building John Mayer's Tone | Klon Centaur

Updated: May 5, 2021

It's no secret that John uses a "no horsie" Klon Centaur Professional Overdrive. While I have built a few of Ceriatone's Centuras, I have a special place in my heart for the Aion Electronics Refractor PCB since it was the first guitar pedal I've built a long time ago. I thought I'd give it a fresh approach this time around using the skills and techniques I've developed over the years. The results is something I'm really proud of.

Ceriatone's Centura documentation assists in figuring out the original Centaur's resistor types (Metal film/Ceramic) in their proper location. The PCB is the fantastic Aion Electronics Refractor PCB. The diodes in this build is 60's NOS Sylvania 1N394 which forward voltage metered out around .38vf. The result is a near 1:1 tone of the original Klon in my opinion :-)
