Klon Centaur

The Klon Centaur (commonly known as the Klon) is an overdrive pedal made by Bill Finnegan between 1994 and 2008. With the Centaur, Finnegan sought to emulate the distortion of a guitar amplifier being played at a high volume. Finnegan's pedal was popular but he struggled to meet demand and his profit margin remained low while used units sold for high prices. Finnegan discontinued his pedal in 2008, having produced around 8,000 in total. In 2014, Finnegan debuted the redesigned Klon KTR, which was outsourced to contracted firms for production.

The Centaur has been credited with popularizing "transparent" overdrives, a type of overdrive intended to increase gain with minimal effect on the underlying tone. Guitar World however described the Centaur as emphasizing certain midrange frequencies and adding thickness to the tone. Numerous manufacturers have created Klon-style pedals, or "klones". As of 2024, used Klon Centaurs have sold for up to $20,000 USD.
