Guitar Fuzz Effect

Welcome back! Anyone who plays guitar for a long time knows this fuzz effect. It's kind of a vintage effect but it still is cool. This fuzz effect module can be bought but why don't you try making one for yourself? In this post I'm not going to go into the in depth mechanism, I will post more about op-amps and will explain in there.

Diagram and a few lines

IC 741 is a very basic op-amp, it can be swapped with any low noise op-amp for better performance.

The input and output 0.47uF capacitors can be replaced with lowered valued capacitors for more trebley response. For more bass response a small valued capacitor can be added in parallel with the 1Mohm resistor.

1Mohm resistor can be replaced with a variable resistor, which will give you the option for controlling fuzz amount.

If the output volume level is too low, you can use a small amplifier to boost it up!
See how.

This circuit takes up a very small amount of current so a single 9V Alkaline battery or six AA sized battery can be enough for this.

It is a very small circuit so it can be built directly into the guitar.

You can experiment a lot with it!

Good luck!
