This API 550b has been fully tested by our expert team and comes with a money back guarantee and lifetime support.
The API 550b is a discrete four-band equalizer in the 500 Series format, rooted in the iconic 550 EQ that helped shape the sound of American recordings throughout the 1960s and ’70s. Built around the legendary 2520 op-amp, it expands on its predecessors with an additional filter band and new frequency selections, offering seven switchable frequency centers per band with up to ±12 dB of boost or cut. API’s signature Proportional-Q design automatically narrows the bandwidth at higher gain settings and widens it for subtle adjustments — delivering musical, phase-coherent results without extra controls. Equally effective as a problem-solver or a tone-shaping tool, the 550b is a timeless studio workhorse trusted by engineers across every genre.
