Vintage multi effect unit with no presets, no banks, no menu, dates back to ca. 1989/90. Even if the housing is plastic, no problem - the plastic is stable. All effects are exceptionally good. The chorus sounds very lush and warm also the delay. The od 2 can be set from mild to full on distortion.
Contains following Boss pedals: Compression Sustainer - CS-3 Overdrive/Distortion - OS-2 Digital Delay - early version of the DD-3 Chorus - CE-3
