Fuzz Distortion

What Is Fuzz Distortion?

Fuzz distortion is an audio effect usually associated with altering the tone of electric guitars. Nevertheless, it can apply to any other instrument or audio signal. Unlike standard distortion pedals, designed to mimic the sound of cranked-up tube amplifiers, fuzz is an electronic component distortion type that changes the whole sonic signature. The sound of fuzz distortion can be described as metallic and thick. Simply put, it is a very rough type of sound.  

Hard Clipping

Fuzz distortion pedals are often pushing the audio signal towards square waveforms. This results in very hard clipping. Consequently, it compresses the sound and adds a lot of odd-order harmonics. Today, a wide variety of fuzz distortion pedals produce this effect differently. Some amplify the signal in order to overdrive the op-amp (like the way tubes distort when pushed too hard). Others send the signal through several stages of diode clipping until they produce a square wave.  

History of Fuzz Distortion

The term "Fuzz "can be traced back to the 1960s when American guitarist Grady Martin recorded an instrumental song using a faulty preamp with his guitar. He released this song on the Decca label, and the song's name was "The Fuzz ". So, Martin is, without a doubt, the discoverer of the Fuzz effect. After that, the first commercially available fuzz distortion device was the Maestro FZ - 1 Fuzz Tone by Gibson company. It quickly became widely popular and used with electric guitars and basses. In May 1965, Keith Richards of Rolling Stones used Maestro FZ - 1 Fuzz-Tone on his guitar riff in the legendary song (I Can't Get No) Satisfaction. The song's success considerably decreased device sales, and all available stock sold out by the end of 1965. It became a favorite of many garage rock and psychedelic bands. The Maestro FZ-1 incorporates a three-germanium transistor circuit with RCA 2N270 devices. It also has two 1.5-volt batteries and a lead cable to connect it to an instrument (bass or guitar). Germanium devices are temperature sensitive, and the effect consistently responds to the incoming signal's amplitude (volume).  

Germanium Transistors

The best fuzz distortion pedals owe their tone to a pair of previously mentioned Germanium transistors. These two components—along with a simple network to govern their functions and connect them to a couple of potentiometers for Volume and Fuzz (or some form of level and drive controls) deliver smooth, warm sound. Fuzz distortion pedals are beloved for their "playability"— the extent to which their pick attack and your guitar's volume control. L can control their response and dynamics after technology associated with the design of Fuzz distortion pedals introduced by silicon transistors. They have more complex and crisper, more defined tones. Both units, with old and new technology, have their distinctive tone. Therefore, they found wide use among many famous modern guitarists.
