Equalizer:  An Equalizer (EQ) is commonly used to alter or balance frequencies by either cutting or boosting. Depending on the equalizer unit, this could either be a specific frequency, like studio units or EQ pedals, or a range of frequencies.

An EQ pedal, like the Boss GE-7 is active. This means that each filter or slider can both cut and boost the selected frequencies. In other words, each slider is a master volume for that specific frequency.  The Boss GE-7  bands control seven octaves: 100, 200, 400, 800, 1.6 k, 3.2 k, 6.4 kHz.  Decibel level can be altered by +/- 15 db.

Simple Definition:  An Equalizer lets you raise or lower high, mids and lows for fine tuning.
