EQ

EQ pedals, also known as equalization pedals or equalizers, are effects pedals that are used to adjust the frequency response of the input signal by boosting or cutting certain frequency ranges. They are often used to shape the tonal characteristics of the input signal and to create a specific sound or effect.

EQ pedals typically feature a range of frequency bands that can be boosted or cut, as well as controls for adjusting the gain and bandwidth of each band. Some EQ pedals also feature additional controls, such as a high-pass or low-pass filter, that allow the user to further shape the sound of the pedal.
