This pedal is a parametric equalizer. Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and ...
The original stand-alone unit was called the ITI ME-230 (Mastering Equalizer 230) and was the first commercially available parametric EQ. [1] [4] Massenburg and Macneal type-set and printed a paper entitled “Parametric Equalization” in 1972 and Massenburg submitted it to the Audio Engineering Society in Los Angeles.
A tone control circuit is an electronic circuit that consists of a network of filters which modify the signal before it is fed to speakers, headphones or recording devices by way of an amplifier. Tone controls are found on many sound systems: radios , portable music players , boomboxes , public address systems , and musical instrument amplifiers .

Gyrators are also widely used in hi-fi for graphic equalizers, parametric equalizers, discrete bandstop and bandpass filters such as rumble filters), and FM pilot tone filters. There are many applications where it is not possible to use a gyrator to replace an inductor:
