Build Your Own Guitar Fuzz Pedal
Rock Out with Your GuitarDescription: Instructables Fuzz Pedal Kit
Skill Level: Intermediate
Assembly Time: 3 to 5 hours
You might have noticed, no matter how hard you rock out with your guitar, it just doesn't sound right. That's because you're missing "Fuzz." Yup, fuzz. Before you can do any serious rocking out, you are going to need to build a guitar Fuzz Pedal. Fortunately, making your own fuzz pedal is a lot easier than it may sound.
Drill bits: 9/32", 1/8", 1/2", 3/8"
|2N3904 NPN Transistor||2N3904(FSC)|
|9V Battery||DURACELL PC1604|
|9V Battery Clip||A104-R|
|1/4" Shaft Knob||JK-902A-R|
Step 1: Review the PartsTake a moment to be sure you have all the required parts.
Step 2: Mark the Top Surfaces of Your Project BoxOn the top surface of your box, measure in one inch from one of the shorter edges. Make two marks that are one third and two thirds of the way between the edges of the shorter distance. These are for the potentiometers. Measure in one inch from the opposite side of the front of the case. Make a mark that is half way between the two edges. This is for the stomp switch. On the side of the case make two marks for the audio jacks, making sure they won't interfere with any of the other parts that will be installed. Following the same logic as the audio jack marks, make one last mark for a toggle power switch.
Step 3: Drill the HolesDrill the two holes for the potentiometers with a 9/32" drill bit. Drill a 1/8" pilot hole for the stomp switch and then widen it to 1/2". Drill two 3/8" holes for the audio jack. Drill a 1/4" hole for the power switch.
Step 4: Solder the ComponentsBuild the circuit as specified in the schematic. The potentiometers, stomp switch, audio jack and power switch to the circuit will be wired in after they have been installed in the case.
Step 5: Attach the Potentiometer WiresAttach a black wire to the center pin of the 5K potentiometer and a red wire to the pin on the right. Attach a black wire to the left pin on the 100K potentiometer and red wires to the two other pins.
Step 6: Attach the Audio WiresAttach red wires to the signal lugs on each of the jacks. Attach a black wire to the ground lug on each of the audio jacks.
Step 7: Install the Audio Jacks and the Stomp Switch
Step 8: Wire the SwitchSolder each of the red audio wires to one of the center lugs on the DPDT switch. Solder together one set of outer pins.
Step 9: Attach the PotentiometersOne of the potentiometer wires will be attached to the DPDT switch later.
Step 10: Cut Out the BracketsCut out two brackets using the template file. Both should be cut out of non-conductive material. I cut out the larger base bracket out of a thin cork mat and the smaller potentiometer bracket out of 1/8" rubber.
Step 11: Place the PotentiometersLine up the rubber bracket with the holes in the case and install the potentiometers.
Step 12: Additional WiringConnect the remaining potentiometer wire in line with the audio-out jack's wire on the DPDT switch and wire from the remaining DPDT terminal lug to the audio-in point on the circuit board.
Step 13: Connect the Power SwitchConnect the red wire from the 9V battery connector to the center terminal of the power switch and another red wire to either of the switches' outer terminals.
Step 14: Install the Power SwitchConnect the black wire from the 9V clip to ground on the circuit board and the free red wire from the switch to +9V on the circuit board.
Step 15: Plug in the 9V Battery
Step 16: Close the CaseInstall the large insulator panel between the circuit board and the bottom plate of the casing and screw the case shut.
Step 17: Attach the Knobs to the Potentiometers
Step 18: Plug and PlayPlug your guitar to audio-in and your amplifier to audio-out.
