Overdrive
Overdrive, Tone, Level pots are replaced.

The Tube Screamer has a drive knob, a tone knob, and a level knob. The drive knob adjusts gain (which can affect the amount of distortion), the tone knob adjusts treble, and the level knob adjusts the output volume of the pedal. The pedal also provides a slight boost to mid-range frequencies, helping to reduce muddiness by cutting bass frequencies; some guitarists prefer this sort of equalization, as it helps to keep their sound from getting lost in the overall audio mix of the band. This, along with its versatility as a simple distortion, has made the pedal very popular for a wide variety of styles and situations.

The original Tube Screamer circuit was created in 1979 by Nisshin engineer Susumu Tamura, who wished to design a pedal that better emulated the effect of playing an overdriven tube amp. As Boss owned the patent for solid-state asymmetrical clipping, Tamura was forced to use a symmetrical clipping design, and rejected several op amps for being too expensive before settling on the JRC 4558D integrated circuit (IC) chip. For audio tests, Tamura used a 1968 F Twin Reverb and a Vibrolux Reverb, and occasionally a Marshall 1959 Super Lead.
