Page 5: Power Section
Fuzzy Joe v1.1 Power section Ok, let’s first address the elephant in the room, the power section. As almost all vintage fuzzes, this one also uses positive ground (yes, yes, technically there is no such thing as positive ground). All purists say you should only use a battery preferably one that is close to death. -
Page 6: Build Sequence
Fuzzy Joe v1.1 I strongly suggest you install the “Sag”. My best tones came from using it and at -9V some transistors from the batch just could not produce a good sound at all! And it is switchable so if you do not agree with me…... -
Page 7: Off Board Wiring
Fuzzy Joe v1.1 Off board wiring Potentiometers In the pictures below you see the correct pin numbering of the pots (Alpha 16mm style). Solder the wires accordingly and it is always a good idea to twist the wires together to create some extra shielding against external noise. -
Page 8: Voltage Inverter Wiring
Fuzzy Joe v1.1 Voltage Inverter wiring R led1 Sleeve Ring Input Sleeve Output Note that R led1 is 4k7 resistors. You can change this value depending on the type of LED you use but 4k7 is safe enough for almost all LEDs for (-)9V. -
Page 9: Biasing
Fuzzy Joe v1.1 Biasing The transistors need to be biased. The best way to do this is by using the bias pots VR2 and VR3. Start by using the following settings: : all the way to the left (or switch SW1 to -9V = connect left and middle pad) -
Page 10: Troubleshooting
Fuzzy Joe v1.1 Troubleshooting All PCB’s have been 100% factory e-tested and out of every batch I receive I build an effect to double check, so there should not be a connection problem on the PCB itself. The board is not working (at all), what now? •... -
