Description

Exceptional vintage 1972 API 553 500 Series signal processor, representing the early years of one of the most influential modular formats in recording history. The 553 is a three-band discrete EQ featuring independent low, mid and high-frequency controls, with the mid band centered at 3kHz for classic presence shaping. API pioneered the 500 Series concept in the late 1960s, originally developing these compact modules as part of its professional recording consoles. That modular approach went on to become one of the most widely adopted formats in modern recording. This early 553 offers a direct connection to the formative years of API and the golden era of American recording. A particularly exciting piece for engineers, collectors and studios looking for genuine vintage API character. Please see photos for cosmetic condition and details. This exceptional piece has been personally curated and inspected by Brandon Meunier, a Guitar Center specialist with a primary focus on high-end and vintage guitar amplifiers, instruments and gear, along with extensive experience across professional audio and other specialized departments. In addition to Brandon's evaluation, this item has been reviewed by members of Guitar Center's most experienced vintage, used and high-end personnel.
