525A 500-Series FET Compressor Module

API

API's classic 1970s FET compressor in 500-series format. Same circuit that lived in the API consoles at A&M, Wally Heider, and every classic rock + soul studio of the era. Hard-knee FET response, fast attack, two attack times. The opposite of a bus compressor — this is the channel processor that grabs vocals and makes them stick in front.
