Professor Yaffle
The Professor Yaffle is the ultimate fuzz platform — designed to let you recreate a huge range of boutique Fuzz Face-style circuits, from the legendary Eric Johnson Fuzz Face to the Roger Mayer Axis Fuzz and even the Analogman Sun Face. If it’s based on a Fuzz Face, you can build it here!
This isn't just another clone board — it’s a carefully designed kit that covers all the key variations, giving you total flexibility to tailor your sound. Because of that flexibility, it’s a little more advanced than our standard Fuzz Face kit. If you're a beginner just looking for a simple, classic Fuzz Face, you might want to check out the basic Fuzz Face kit first.
You'll need to check the pinout of your transistors before soldering, since this board can accept a variety of types — but don’t worry, the instructions walk you through everything you need to know. Once built, the PCB neatly hangs from the pots inside the enclosure, just like a proper boutique build.
We rate this kit about 5/10 on our difficulty scale — a perfect step up if you’re ready for a more flexible, rewarding build.
Fits a JP1590B enclosure, are you ready to rock?
