Centaur Overdrive

The Klon Centaur Overdrive is an iconic pedal known for its harmonically rich distortion and unique design. Developed by American engineer Bill Finnegan, the Centaur aimed to recreate the distortion of a guitar amplifier at high volume while maintaining a "big, open" sound with a hint of tube clipping. The pedal features germanium diodes and custom-made components, including the cast enclosure, knobs, and pots.

The pedal's design includes a treble control for EQ adjustment, an output control for overall effect volume, and a gain control for blending clean and dirty signals. Additionally, modifications and experimentation can be performed, such as changing tone capacitors, socketing diodes and op-amps, and implementing a bass guitar mod.

The Klon Centaur has inspired numerous clones by different manufacturers, and its legacy continues to influence the guitar effects pedal industry. The pedal has been used by renowned guitarists and continues to be highly sought after in the market.
