In the jargon of producers and recording engineers, equalizers fall into two general categories: "surgical" and "character." The surgical EQ is used correctively, e.g. when you wish to focus on a problem frequency without affecting the neighboring frequencies. Much like a surgeon, you want to go into a narrow band with a very precise cutting tool–an appropriate simile since we primarily "cut" or reduce problem frequencies. Examples would be taming harsh frequencies on cymbals; sibilance or plosives in vocals; fizz or wool on distorted guitars; or overly woofy bass.
