Fuzz FactoryThe Fuzz Factory is a five-knob fuzz pedal with huge range of sound possibilities. This is classic DIY pedal project that can be built with either germanium or silicon transistors.
Enclosure and wiring Step 4 of 4
You should install all the parts (DC and 3.5 jack connectors, 9V battery clip, 3PDT foot switch, assembled PCB...) in the enclosure. The led diode and its holder can be moved to the place where you want, just respect the polarity. The round side and longest leg is the anode (marked as a square pad in the PCB). It is possible that you need to remove the small metal tag from the potentiometers in order to easily install them in an enclosure.
You can create your own element distribution and use many types of enclosures. It is recommended to use a metal enclosure and connect it to the ground in order to attenuate the noise (usually the GND of tthe input and output jacks are in contact with the enclosure). For this project, you can use the 1590BB enclosure. After the drilling, you can paint and decorate the enclosure as you desire. Finally, install all the elements and you can beguin with the wiring.
For the wiring you should use 24 AWG stranded wire. Wire all the elements as indicated in the following diagram, for the ground (GND) no mater the order you use if all the elements are connected.You can power up the circuit with DC adapter (9V) or a battery. The diagram shows the connections to use the DC connector as negative tip (standardized Boss style 2.1 mm with a negative tip orientation). The led can be placed directly on the PCB, wire the pin marked as PL (Pin Led) to the 3PDT footswitch.
You can also use the PCB for 3PDT footswitch. It will help you to wire all the components, keep a neat circuit and reduce the noise. The PCB also includes pads for the led and its current limiter resistor.
