The Boss ME-5 Guitar Multiple Effects was the first multi-effects floor unit the company produced. The Compressor, Overdrive/Distortion, Equalizer, Chorus/Flanger, and Digital Reverb/Delay effects it used simply employed the internals from the made-in-Japan Boss modules offered at that time (specifically the CS-2, DS-1, OD-2, RV-3, EQ-1, CE-1, DD-2, and BF-2). Because of these vintage pedals being embedded in the unit, these have become increasingly sought after. 

Years of Production: 1988 - ca. 1990s
