From the post

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. See Figure 3 in our Guitar Pedal Footswitch and Jack Wiring article for the recommended footswitch and I/O wiring.

×110nF10nA Solen cap was used in this build but most 10nF caps will work well.; (C-FSD01-1000)
×12uF2uA Sprague cap was used in this build but any 2 to 2.2 µF electrolytic cap will also work well.; (C-SA2-50)
