This used ARP Odyssey MKIII 2823 Synthesizer is a vintage analog monosynth from the late 1970s, renowned for its bold, cutting sound and expressive capabilities. Featuring a duophonic keyboard with 37 keys, this unit includes two voltage-controlled oscillators (VCOs), a resonant low-pass filter with switchable 2-pole/4-pole modes, sample-and-hold, ring modulation, and envelope generators for dynamic shaping. The MKIII model is identifiable by its black and orange color scheme with updated four-pole filters and CV/gate inputs for external control. In good condition with expected cosmetic wear for its age, all functions are fully operational. Perfect for collectors, studio musicians, or anyone seeking authentic analog tone with vintage character.
