Ever since the original Klon Centaur ceased production, it has become the most mythologized piece of gear in the guitar world. Known for its “transparent” overdrive and legendary mid-hump, original units now command four-figure prices. Fortunately, modern pedal builders have cracked the code, offering everything from part-for-part recreations to modern evolutions.
Whether you want a tiny boost or a massive vintage-style enclosure, here is the ultimate guide to every top-tier Klon clone (or “Klone”) available today.
What is the Klon Centaur? The Story Behind the World’s Most Mythical Overdrive
The Klon Centaur is a legendary overdrive pedal created by Bill Finnegan in the early 1990s. Designed to deliver the unmistakably rich and dynamic sound of a cranked tube amp at lower volumes, it quickly earned a cult following. As an owner of two original units, I can tell you the hype regarding their tone, clarity, and responsiveness is well-deserved.
However, in 2026, there are now many options that are indistinguishable from the original circuits and at a range of affordable price points. Before I break down my recommendations for ones you should try and where to find them, let us look at what the famous Klon pedal’s transparent overdrive is all about and some of the pedal’s design history.
Transparent Overdrive
Unlike typical overdrive pedals that heavily color your signal, the Klon is the definitive “transparent overdrive.” It works by blending your clean signal with the overdriven one, preserving your guitar’s natural voice while adding smooth, harmonically rich gain. With its signature germanium clipping diodes, 18V internal headroom, and carefully voiced EQ, it has become the gold standard for pros and tone purists alike.
The Birth of a Legend: History of the Klon Centaur
This isn’t a history of Greek mythology, but for guitar aficionados, the “Centaur” made by Klon Siberia is just as legendary.
In the late ‘80s, Bill Finnegan was gigging the bars of Boston with a Telecaster through a Fender Tweed Twin. He found his “sweet spot” at a volume of 6 or 7, but sound engineers at smaller venues constantly forced him to turn down to 3 or 4. At those lower volumes, his tone lost its harmonic richness.
To fix this, he tried a vintage TS9 Tube Screamer, but he wasn’t satisfied. He felt the TS9 compressed the signal too much, had an unpleasant midrange character, and cut out too much bass.
Finnegan teamed up with MIT graduate Fred Fenning to invent a completely new type of overdrive. After years of development, the Klon Centaur Professional Overdrive was released in 1994. Every unit was hand-built by Finnegan, who famously covered the circuit boards in black epoxy (goop) to keep the design a secret. It remained uncopied for over a decade until the “secrets” of the gooped boards were finally revealed in 2008.
What Makes the Klon Centaur So Special?
When the schematics finally leaked online, they confirmed that the Klon was a truly original design. Here is why the “K-Style” circuit is superior to standard overdrives:
-
The Dual-Gang Gain Pot: This is the “magic” of the Klon. The gain control is actually a blend feature. At low settings, it acts as a clean boost; as you turn it up, it seamlessly blends in the overdriven signal. This prevents the heavy compression found in other pedals.
-
Touch Sensitivity: Because of the clean blend, the pedal retains the full dynamic range of your guitar. It responds to your playing—pick lightly for a clean chime, or dig in for a gritty growl, just like a valve amp on the edge of breakup.
-
Voltage Doubling (18V Headroom): The pedal converts a standard 9V power supply to 18 volts internally. This increases “headroom,” allowing the signal to stay clear and punchy at higher volumes before it begins to compress.
-
Germanium Clipping Diodes: While many pedals use cheap silicon diodes, the Centaur uses germanium. These offer a smoother, more “musical” distortion that mimics the natural clipping of vacuum tubes.

Frequently Asked Questions (FAQ)
What is the “Klon Buffer”?
The original Klon featured a high-quality buffer that stayed active even when the pedal was off. This helped preserve high-end frequencies over long cable runs. Most high-end clones (like the Tumnus or Archer) include this buffer.
Is it better as a boost or an overdrive?
While it has a unique overdrive sound, most professional guitarists use Klones as a “Clean Boost” (Gain low, Volume high). This pushes a tube amplifier into its own natural distortion, creating a “more of what you already have” feel.
Why are germanium diodes important?
The original Centaur used specific “magic” germanium diodes for clipping. These diodes create a smoother, more musical distortion. High-end clones like the Archer Ikon and Centavo go to great lengths to source these specific components.
Our Thoughts
Whether you are chasing the exact compression of a gold-box original or simply looking for a “transparent” way to push your favorite tube amp, there has never been a better time to be a gear collector. As someone who keeps two original Klons on my own shelf, I can tell you that while the magic of the vintage units is real, the gap between the “myth” and these modern recreations has never been smaller.
From the studio-grade precision of the Origin Effects Halcyon Gold to the incredible accessibility of the Behringer Zentara, the “K-style” circuit is no longer a gatekept secret—it’s a versatile tool available to every guitarist. The right choice ultimately depends on your board space, your budget, and how much you value those specific germanium diodes.
No matter which pedal you choose from this list, you’re adding a great option to your signal chain that will help your guitar cut through the mix with clarity and grit.
