What the Klon Centaur actually does (and doesn't do).

I owned a gold non-horsie from 2007 to 2019. I sold it for a stupid amount of money to a dentist in Munich. I bought a KTR a year later because I missed the sound and not the anxiety of owning the sound. So I have spent about nineteen years with this circuit in some form on my board, and I would like to tell you what it does, what it doesn't do, and why the conversation around it is mostly about the wrong things.

The Klon is a clean boost with a dirt option bolted on. That is the whole pitch. Bill Finnegan built a pedal that lets you push a tube amp into its own breakup without coloring the front end the way a Tube Screamer does. The Tube Screamer scoops your bass and humps the mids around 720 Hz. That is a feature when you are playing a Strat into a Fender clean and you need cut. It is not the Klon's job. The Klon is closer to flat. Closer.

What people get wrong is that they think it sounds 'transparent.' It does not. Mira (mira.alves) said it well in a thread last spring: 'The Klon is honest about its bass. It is dishonest about its top end.' She is right. There is a treble lift that arrives somewhere around 3 kHz that makes a single-coil Strat sit forward in a mix in a way a clean boost shouldn't. That lift is most of the magic. The rest is the diode-clipping section running in parallel with a clean path, which is the trick the clones spent a decade reverse-engineering and then telling you was the secret.
