Katzenkönigin

Catalinbread’s Katzenkőnig combines elements of a Tone Bender MkII fuzz with a Rat distortion to create something that sings like a fuzz but is tight like a distortion. It has a wide range of response that covers from a beautiful singing tone, to tight, harmonically-rich crunch, all the way to fuzz mayhem.

It took me several tries,  but I finally made mine following this stripboard layout.
