Build - Pedal Project: Blackout Fuzz

Blackout Fuzz: NPN Fuzz Stripboard Layout

The Blackout Fuzz is a stripboard layout for an NPN fuzz using as many black pedal parts as possible. This layout includes an LED but otherwise stays true to the classic fuzz circuit. The NPN layout allows for use with a basic 9V pedal power supply and can be daisy chained with other standard pedals. The parts selected are high-end with an emphasis on quality and the blackout appearance of the pedal.

Parts List

Potentiometers
1 kΩ LinearR-VTOCOS-1KLTocos was used on this build but Alpha or CTS are also great choices
500 kΩ AudioR-VTOCOS-500KATocos was used on this build but Alpha or CTS are also great choices
Transistors
Q1 & Q2P-Q2N1692N169 germanium transistors were used in this build but many NPN transistors (including silicon) will also work well
Capacitors
10 nF (.01 uF)C-FSD01-1000A Solen cap was used in this build but most 10nF caps will work well.
2 uFC-SA2-50A Sprague cap was used in this build but any 2 to 2.2 uF electrolytic cap will also work well.
20 uFC-SA20-500A Sprague cap was used in this build but any 20 to 22 uF electrolytic cap will also work well.
Resistors
470 ΩR-I4701/2W carbon comps were used on this build but 1/4W or 1/2W carbon film or metal film are also great choices
R LEDR-I470470Ω was used in this build along with P-L352. Use an appropriate value for the LED if using something different.
8.2 kΩR-I8D2KThis is the collector resistor for Q2. Use an appropriate value for your Q2 transistor. 8.2KΩ is used in the original fuzz circuit.
33 kΩR-I33KThis is the collector resistor for Q1. Use an appropriate value for your Q1 transistor. 33KΩ is used in the original fuzz circuit.
100 kΩR-I100K
