Recorded using a Les Paul with Burstbucker pickups into a Twin Reverb model with the normal input. The overdrive pedal and amp are set at default settings. A touch of reverb added for depth.

The Klon Centaur is a guitar overdrive pedal developed by Bill Finnegan between 1990 and 1994. The pedals were made manually by Finnegan. The Centaur is characterized as a "transparent" overdrive, meaning it adds gain to the signal without significantly altering the tone of the guitar.

Depending on the settings of the control knobs, the pedal can act mostly as a clean boost, adding mostly volume and minimal coloring to the sound. This can be used to drive the input valve stage of the amplifier to use the characteristic distortion sound of an overdriven guitar amp. Alternatively (or additionally) the controls can be set to distort the sound signal in the pedal, where two germanium diodes can perform waveform clipping (see clipping (audio)). The "gain" knob is a double potentiometer (a "dual-ganged gain pot"), which controls bass and middle frequencies. Other knobs are treble and volume.
