From the vendor
The Fulltone Catalyst is an amazing pedal, containing a clean boost function, an overdrive, distortion, and fuzz all in one. The Catalyst is best at creating non-compressed crunch tones and non-compressed distortion/fuzz sounds, and is unique in its ability to clean up as you turn the volume down. This pedal also comes with a simple 2-band EQ and a Flame/Spark switch, which turns the pedal into a Fuzz/Distortion and an Overdrive, respectively. It's so versatile it ends up in virtually any genre of music.
