Guitar effects pedals come in varieties aspects, but in short,most guitar effects can be sum up in four basic themes: Reverb/Delay, Dynamics, Distortion,and Pitch Modulation. If you want to research those ,you may find many useful informations which is out of your expected. All of these four factors come in a variety of configurations which were initially, single effects built into guitar pedals, called stomp boxes, from then on multi-effects processors built into both tabletop units ,floor pedals and rack mount. Many also cover drum machines and headphone jacks for practice purposes.
Guitar distortion has three types of effects which are common based on the sound includes distortion and overdriven tube amplifier, overdrive, and fuzz.
Here I just want to talk something about guitar distortion effects, then help you and me make a clear mind of its effect.
Most of us may probably have heard about what a "clean" electric guitar sounds like. That is because an electric guitar makes when plugged straight into an amplifier without using any guitar or amplifier effects.And sometime we may hear the sound is “dirty”, we call that distortion.
Many guitar amplifiers have a distortion channel or you can called it overdrive, which will give it that dirty sound. The over drive distortion allows the chords to become more tenser than normal. What you should notice that is the clean tone will give you a more dissonant sound compared to your overdrive distortion.
The overdrive distortion also changes the melodies when you play. Sometimes you may find that your music will sound better with wider intervals. You may also find yourself playing in an angular style. These are tendencies that are naturally brought about by the effect. This brings more intensity to the playing sound. The other way you can achieve distortion is through the use of a standalone distortion pedal, it can make distorted sound you just need to adjust an amplifier with a distortion channel.
