Bazz Fuss

The Bazz Fuss is an incredibly simple fuzz effect for bass (though can be used with guitar as well). It only uses a handful of parts and you can put it together on your breadboard in about a minute. I would have done this as another "episode" of It Came From Radio Shack!!! but there are a couple more things you can't get there (metal case and 3PDT switch), the actual components though, you can find at Radio Shack. I got mine there for just less than $20.

Parts List (* Not available at Radio Shacks)
2n3904 NPN Transistor
0.1uF Capacitor (Poly-Film)
4.7uF Capacitor (Electrolytic)
100kΩ Resistor
100kΩ Potentiometer
1N914 Diode
Rubber Feet
Metal Case*
3PDT True Bypass Footswitch*

All together, these things cost about $35.

I'm basing my build on this schematic from

The circuit is insanely easy to build and can be thrown on a breadboard in less than a minute. Here's what mine looks like on the breadboard.

I also added a 1MΩ resistor for a little voltage divider to get it to work on mine. If you have a problem with your circuit working, just try adding that.

After testing it out on the breadboard for a bit, it was time to solder it up. I decided to use sockets for the caps and transistor, since there are many substitutions for these parts that add their own flair to the circuit.

The finished circuit.
The original enclosure I was going to use was too small and I could not fit the battery in, so until I can get another one (I'll probably order it next week), I'm using a crappy little plastic box I grabbed at Radio Shack a little while back. Here's the final product all boxed up.

  1. can you draw me the voltage dividing transistor into the scheme? :) thx
