Based on the classic Aphex EQF-2 500 series equalizer made in 1976, the new EQF 500 is a modern tribute. The EQF-1 and EQF-2 were not made by API, and were some of the first 500 series modules. They were designed for the API modular consoles. The first EQF-1 was built by hand, and started a small production run. The EQF-2 was another breakthrough that included shelving EQ for the high and low bands.Aphex EQF 500 Audio Equalizer 500 Series Module
