FX80 Compressor
An early FX80 from late 1983
The FX80 was one of the original ten DOD FX-series pedals that debuted in 1982. Featuring just Level and Compression knobs, the FX80 essentially replaced the 280 Compressor in DOD's product line (although it is unclear exactly how the circuits are related). The FX80 remained in production until it was replaced by the FX80B in mid-1985.
