Fuzz Face™

This is the Fuzz Face™ project know as FF5, the “5” denotes that there are at least 5 different versions that you can build with this project.  Here they are!


For a simple project, we recommend the NPN Silicon Transistor Version. If you want to build a Germanium Transistor version, get your transistor set from Small Bear Electronics LLC and use the resistor values that he sends with the transistors. His resistor designations (R2, etc) are not the same as the designations on these projects. Here is the cross reference:

  • SBE R3 – GGG R2
  • SBE R4 – GGG R4
  • SBE R5 – GGG R5 (may not be needed if you use R5T trimmer)
  • SBE R6 – GGG R3

If you have a common power supply to power your pedals, the negative ground version will work with your other pedals on a common power supply. See the Charge Pump Wrapper below to get your positive ground pedal on a common power supply with all your other pedals.


 Trimmer or No Trimmer

The Germanium Transistor version and The NPN Silicon Transistor version layouts both have a 10k trimmer (R5T) that is not shown in the schematic.  We believe this is a worthy addition to the circuits, giving you more options for the ultimate sound you want.  If you don’t want to use the trimmer, here is the Fuzz Face™, No Trimmer Diagram  mentioned in the Instructions file.  This diagram is for the Germanium Transistor version, but the jumper is the same for the NPN Silicon Transistor version.


Common Files For All Versions


Fuzz Face Germanium Transistor (Dallas Arbiter) Version


Fuzz Face Silicon Transistor (Dallas Arbiter) Version


Easy Face  (Joe Gagan’s) Version


 Boutique Late 60’s Fuzz Face Version


 Boutique Late 60’s NPN Fuzz Face Version

This can use silicon or germanium NPN transistors with excellent results. Bill of Materials is the same as the “Late 60’s Bill of Materials above.


Boutique Early 70’s Fuzz Face Version


Fuzz Face PNP Germanium Transistor With Charge Pump Version

The addition of a charge pump on the input power, gives you the ability to daisy chain power to your PNP Positive ground pedal with all your other negative ground pedals! Eliminate any need for special considerations when powering your Fuzz Face with the other pedals on your pedal board.


Buy a FF5 Complete Kit. Includes all the parts and materials you need to build one, all for about the price you would pay for a PCB and parts.


Would you like a Ready to Solder Circuit Board for this project? Note: If you buy the kit, the Ready-to-Solder Printed Circuit Board (RTS PCB) is included in the kit.  You do not need to purchase this Ready to Solder Circuit Printed Board if you buy the kit.
