The custom-molded champagne-gold chassis offers Gain, Treble, and Output controls on the front panel, along with a Mod switch on the back that engages the Jeff Beck Mod, which changes the value on the high-pass filter to provide an extended low-end response from the guitar's lower strings.

Main Uses
Clean Boost
With the Gain down and the Output up, the pedal acts like a clean boost that adds a little bite to the channel as you increase the Gain; this was a very popular use for the original Klon Centaur pedal.
Drive Dirt
The original pedal is also well known as a great pedal to add in front of a dirty channel, whether used with a British (think Marshall) or American (Boogie) amp. Unlike the clean boost settings, players often engage the gain more here, so it hits the channel extra hard, with overdrive coming from the pedal.
Transparent Overdrive
If you want to take a channel to a nice transparent overdrive sound for rhythms or gritty solos over clean parts, the Gain knob has a lot on tap and offers a wide range of usable saturation while keeping the character of the amp and guitar well preserved.
