Fuzz is one of the classic guitar effects, and this simple circuit generates it quite well. The circuit is so compact that it can be built into guitars or amps that do not have built in fuzz to add that capability to the instrument. The circuit does not use much battery power, so a standard alkaline battery will last many years even with daily use.

I built it, its ok. Not the best sound. My next mod to the circuit will be to use two 1N4148 diodes in series for the feedback circuit. This will give a more "rounded" edge to the distortion and hopefully remove some of the "popping" experienced when using a high output Sheraton guitar.. BTW; you can use electronic simulation software such as Proteus - ISIS to simulate the circuit and monitor how it effects the waveform. This will answer questions such as "how can a variable resistor effect the signal" or "are the capacitor values critical".

i got it working at last i was given the wrong caps IT WORKS GREAT the i/p and o/p caps i put in are polyester same value. if you can alter it to switch thru so it is not on fuzz all the time i would be a happy bunny ta huddy

heey people, I have some questions, about how you can make you own sound. I'm just started with electronica for my school project. But I want to know, How you can change the cinussignal into fuzz Signal or other signals like heavy metal. What I do know is that, you can make the sinus signal different, if I use some components to make the signal in to a Fuzz Sound.. srry for my english. I'm dutch actualy. anyway.. I hope you understand what I'm talking about.

Does this work with bass? That's what I need it for, but I'm not sure if it's worth it if it won't work.
