How to Build a Fuzz Box
- 1). Choose a fuzz effect schematic that contains the features you want. In addition to fuzz distortion, you might want tone and volume controls.
- 2). Make a list and buy all of the electronic components in the schematic. For the main switch -- the one that triggers the effect -- in the schematic, buy a heavy-duty switch that can withstand the pressure from your foot. Purchase a knob for each potentiometer, an IC socket for each chip, a battery clip if the circuit is battery-powered, copper-clad stripboard and a DC power jack if you're using an AC adapter for power.
- 3). Build the circuit on breadboard according to the schematic.
- 4). Test the circuit by adding power and turning it on for a few minutes. If you smell smoke, unplug the power source immediately -- there is something wrong with the schematic or your built circuit. If you don't smell smoke, plug your guitar and amplifier in and test the circuit's sound and controls.
- 5). Draw a layout of the copper-clad stripboard on graph paper or using graphic design software. Draw the strips of copper and the holes to scale, so it is in proportion with the stripboard.
- 6). Draw and label the components using the circuit on the breadboard and schematic as guides. Draw components to scale, and don't squash them together. Draw symbols or use certain colors to indicate where to cut the copper tracks and where wires are attached to the board, if necessary.
- 7). Transfer the circuit from the breadboard to the copper-clad stripboard. Use your drawing and the schematic as guides. Cut the copper tracks with a track cutter, if necessary.
- 8). Solder components to the board with a soldering iron. Solder heat-sensitive components, such as diodes, last. Do not solder chips to the board; solder the IC sockets, and put the chips in them when you're done soldering everything.
- 9). Purchase a metal box that is large enough to accommodate the circuit and withstand pressure from your foot.

Measure the widths of the external components -- potentiometer shafts, DC power jack, audio sockets and switches, for example -- with a ruler. Also measure their covers, like the knobs that cover the potentiometers' shafts. - 11
Mark and label the locations of the external components on the metal box with a marker. The sides are good locations for the power and audio sockets. The top is the best place for switches and potentiometers. Leave enough space between components so your holes don't overlap when you start drilling. Covers, like knobs, should not be touching. Use your measurements and ruler to get the spacing right. - 12
Drill holes into the box using the appropriate high-speed steel drill bit sizes. - 13
Wipe debris off the enclosure with a rag. - 14
Put the circuit inside the box. Pull external components through their holes and put their covers on. The covers help keep the circuit in place. - 15
Decorate the box with stickers, markers or paint.
