Author:randofo    Randy Sarafan loves you!I am the author of the book '62 Projects to Make with a Dead Computer' and Community Manager here at Instructables. I'm always sharing tons of awesomeprojects. Subscribing to me = fun and excitement!

Intro:  Fuzz PedalOnce you have your guitar and learned how to play in time with a metronome, the only thing left to do is rock out. However, as you might have noticed, no matter howhard you rock, it just does not sound right. That is because you are missing something. As many guitarists will tell you, the secret to rocking out is actually fuzz. Beforeyou can do any serious rocking out, you are going to need to build a fuzz pedal. Fortunately, making your own fuzz pedal is a lot easier than it may sound.

Step 1: Go get stuffYou will need:

- (x2) 2N3904 NPN Small Signal Transistor (Model: 2N3904 | Catalog #: 276-2016)- (x2) 100K Ohm 1/4-Watt Carbon Film Resistor (Model: 271-1347 | Catalog #: 271-1347)- (x2) 10K Ohm 1/4-Watt Carbon Film Resistor (Model: 271-1335 | Catalog #: 271-1335)- 22 uF Electrolytic Capacitor (Model: 272-1026 | Catalog #: 272-1026)- 0.1µF 50V Hi-Q Ceramic Disc Capacitor (Model: 272-135 | Catalog #: 272-135)- 0.01µF 500V 20% Hi-Q Ceramic Disc Capacitor (Model: 272-131 | Catalog #: 272-131)- 10K-Ohm Horizontal-Style Trimmer (Model: 271-282 | Catalog #: 271-282)- 5K-Ohm Linear Taper Potentiometers (Model: 271-1714 | Catalog #: 271-1714)- 100K-Ohm Audio-Taper Potentiometer (Model: 271-1722 | Catalog #: 271-1722)- Multipurpose PC Board with 417 Holes (Model: 276-150 | Catalog #: 276-150)- SPST Flatted Metal Lever Toggle Switch (Model: 275-634 | Catalog #: 275-634)- 1/4" Mono Panel-Mount Audio Jack (Model: 274-255 | Catalog #: 274-255)- Hexagonal Control Knob (Model: 274-407 | Catalog #: 274-407)- Fully Insulated 9V Battery Snap Connectors (Model: 270-325 | Catalog #: 270-325)- Enercell® Alkaline 9 Volt Battery (Model: 23-853 | Catalog #: 23-853)- DPDT specialty stomp switch- Sturdy metal project box

Step 2: MarkOn the top surface of your project box, measure in one inch from one of the shorter edges. Next, make two marks that are 1/3 and 2/3 of the way between the edges ofthe shorter distance. These will be for the potentiometers

Measure in one inch from the opposite side of the front of the case. Make another mark that is 1/2 way between the two edges. This hole is for the stomp switch.

On the side of the case make two marks for audio jacks where you would like, so long as 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: DrillDrill 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.

Finally, drill a 1/4" hole for the power switch.

Step 4: SolderBuild the circuit as specified in the schematic.

For now, don't worry about attaching the potentiometers, stomp switch, audio jack or power switch to the circuit. These will be wired in later, after they have been installedin the case.

Page 6: Fuzz Pedal

Step 5: WiresAttach a black wire to the center pin of the 10K 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: Audio wiresAttach a black wire to the ground lug on each of the audio jacks. Attach red wires to the signal lugs on each of the jacks.

Step 7: InstallInstall the audio jacks and the DPDT stomp switch into the metal case.

Page 8: Fuzz Pedal

http://www.instructables.com/id/Fuzz-Pedal/

Step 8: WireSolder each of the red audio wires to one of the center lugs on the DPDT switch.

While you're at it, solder together one set of outer pins.

Step 9: AttachAttach the potentiometers to the circuit board as specified in the schematic. Keep in mind that one of the potentiometer wires will be later attached to the DPDT switch.

Step 10: Cut bracketsCut out two brackets using the template file attached to this step. They 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.

Page 9: Fuzz Pedal

Step 11: Put in the potsLine up the rubber bracket with the holes in the case and install the potentiometers into the case.

http://www.instructables.com/id/Fuzz-Pedal/

Step 12: More wiringWire the remaining potentiometer wire in line with the audio-out jack's wire on the DPDT switch.

Connect a wire from the remaining DPDT terminal lug to the audio-in point on the circuit board.

Step 13: Power switchConnect the red wire from the 9V battery connector to the center terminal of the power switch. Connect another red wire to either of the switch's outer terminals.

Step 14: SwitchInstall the power switch into the case.

Wire 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: PowerPlug in the 9V battery.

Step 16: Case closedInstall the large insulator panel between the circuit board and the bottom plate of the casing.

Screw the case shut.

Step 17: KnobsAttach your knobs onto the potentiometers.

Step 18: Plug and playPlug your guitar to audio-in and your amp to audio-out. Then, rock out.

 BusyHands says:  Jul 14, 2011. 9:01 AM  REPLYNicely done instructable. An audio project could really use a sound example or a video demonstrating how the box works, though!

 andreq says:  Jul 14, 2011. 6:15 AM  REPLYI've done something similar some years ago, cloning a DOD 250 overdrive pedal.

Here's a website with a lot of information about Effect Pedal and other guitar related gadget for DIYer.

http://www.generalguitargadgets.com/projects

The nice thing is that most of the projects are fully open source and contain a PCB transfer layout ready to go.

 jakdedert says:  Jul 10, 2011. 12:08 AM  REPLYNice, simple circuit...but what does it do? I know what fuzz is, of course, but how does it sound; or do I have to build it to find out? Also, can you detail thefunctions of each pot in the circuit?

I don't see anything in the video or instructions about the actual operation of the unit.

 randofo says:  Jul 10, 2011. 8:25 AM  REPLYOne on the left is gain and the one on the right is volume. The trim pot inside is for fine tuning.

I'll post a video soon.

 denry12 says:  Jul 9, 2011. 1:36 AM  REPLYVery nice instructable.I just wanted to complain about the on/off switch. Probably a matter of taste, but factory made pedals (and mine :D) use stereo input jack for powerswitching. If mono jack is connected to input, pedal is powered up.http://beavisaudio.com/techpages/StompboxWiring/StompboxWiring96.gif

Just thought that maybe I could educate someone ;)

 casabonita69 says:  Jul 8, 2011. 10:03 PM  REPLYis there a way to make the stomp switch both the switch for power and fuzz?

 thewizard42 says:  Jul 8, 2011. 11:39 AM  REPLYYou can completely bypass using a power switch with a stereo 1/4in jack for the input, using the part the jack for the ring to open and close a connection toground when you plug in the cable.

 vishalapar says:  Jul 8, 2011. 4:01 AM  REPLYHow do you take such beautiful pictures!My pictures background is always messed up!Please tell me how do you get such awsome pics!Thanks!

 Schmidtn says:  Jul 8, 2011. 9:59 AM  REPLYAnother nice write up. Is there a video of what the pedal sounds like? Fuzz comes in a lot of flavors. Also, have you tried replacing your DPDT stomp switchwith a 3PDT foot switch so you can add an LED on/off indicator? Those come in super handy and aren't too hard to wire up. Looks like a great write up, justwish I knew what it'll sound like before I build it.
