Distortion and overdrive are types of audio signal enhancement that are employed to change the tone of amplified electric musical instruments like guitars. Typically, this is accomplished by increasing the gain of the instrument, which results in a “fuzzy,” “snarling,” or “grinding” tone. Depending on the type and degree of distortion used, the effects change […]
