This is an effects pedal that copies the circuit model of the legendary Klon CENTAUR. It uses WIMA capacitors and metal film resistors in the FINE GOLD version, and I believe it also uses many parts that are no longer in production. Also, the size is compact, and the specifications would be expensive if a manufacturer made it with these parts and construction. It has a wide range of sounds, including a valuable germanium diode switching SW. I think there are various uses, such as using it as a warm overdrive for a crunch sound or as a booster. It can be powered by batteries and has true bypass.
