From the post
Here's a new one from Catalinbread for #fuzzfriday. The Katzenkönig–the cat king for those of you who don't sprechen sie Deutsch–is a silicon tonebender-type fuzz with some RAT features thrown in. Catalinbread was kind enough to publish the schematic in the manual for this effect. Pots can all be board mounted using right angle PCB pots mounted from the solder-side of the board. The exact transistors used in this effects weren't published in the manual schematic, but lower gain NPN silicons should do the trick. Socket and experiment with your favorites.
Edit Oct. 14: Original transistors are BC550B, in the 300-400 hfe range. 2N3904s will work well also.
