This rounds out the peaks of the signal “softer” and provides a little tube-like tone. Two diodes are connected on the feedback-path of an opamp or a transistor. This creates more overdrive-like sound than “hard” clipping distortions. 3) “Soft” diode clippingĪnother very common method. Check out MXR Distortion+ and ProCo Rat to see what I mean. Two diodes shunt to ground the opposite way around will cut away the peaks of the signal and thus, create distortion. This is a very common way to create distortion. Unipolar transistors, such as JFETs and MOSFETs have a softer, more tube-like tone. Germaniums were used in the late sixties on the original Fuzz Face, for example. Germanium transistors have a little smoother sound. Silicon transistors make a nasty, metallic sound. Different types of transistors distort differently. Check out different Fuzz Face-like designs to see what I mean. Usually fuzzboxes use overdriven transistors. Just like overdriving tubes, transistors are being overdriven by setting them to run at the top of the amplification range. Here are the most common distortion effect types: 1) Overdriving transistors

Usually distortion effects use solid state circuitry like transistors, opamps and diodes, but there are a few commercial tube overdrive effects available like the Chandler Tube Driver and Matchless Hotbox. Nothing can mimic tubes, although there are a million different “tube-sound distortions” available, they just can’t make the real sound of tubes (there are pretty good ones though). The ultimate distortion/overdrive comes from tubes which are overdriven so that it creates a smooth singing sound. For example Craig Anderton’s Tube-sound Fuzz is actually an overdrive unit. These don’t apply to all effects on the market, for example Craig Anderton calls almost all of his distortions “fuzz”, no matter if it’s a distortion, overdrive or fuzz. Crunch has a sound that resembles the sound of breakfast cereals crunching combined to a guitar sound (I don’t mean snap, crackle and pop). Crunch is not a specific type of distortion, but mild overdrive or distortion. Fuzz is a metallic and very rough type of distortion that turns the sound of a guitar into a fuzzy sound. Overdrive is a natural and smooth sound, while a distortion is more rough.
They are words describing the type of distortion an amp or an effect gives out. When talking about distortion, you can usually hear the words overdrive, distortion, fuzz and crunch. Now we’re going to discuss the methods of creating distortion with effect boxes. Now, most amps have a distortion control, but distortion effects are still popular. Later in the sixties, the first distortion effect boxes were made to simulate the sound of razored cones and overdriven amps. The only way to get distortion was to turn volume to eleven and hope the tubes didn’t melt (or the neighbors didn’t call the cops! Coming to the sixties, guitarists razored the speaker cones to make a fuzzy sound. In the mid 50’s, when electric guitars became popular, all amplifiers were designed for vocals, and they didn’t really give the edge guitarists wanted.
