API Like Classic EQ
Based on the API 550A this classic EQ is a mainstay in professional studios worldwide. Dial in your sound in no time by finding the frequency you want, then boost or cut to taste.
You can also select whether or not to use a shelf or bell curve on the low and high frequencies with the Selector Buttons.
The middle button narrows the width of the MF band, giving you more precision controlling the middle frequency spectrum.
