DOD FX80-B Compressor Sustainer Vintage Made in USA

Replacing the original FX80, the DOD Compressor Sustainer FX80B was introduced to the DOD line in 1985. A third knob to control how quickly the compressor went into effect was added in the FX80B for added dynamic control, being labeled Attack between 1985 and 1987 and Release from 1987 onward. This pedal is from 1987 or later.
