Rare Akai Professional EVI1000 Electric Valve Instrument with its dedicated EWV2000 analog synthesizer module. Rare as it was produced in a few copies in the mid 80s and used by professional musicians. As shown in the photo, the appliance shows signs of use in the most contact points. It has no breaks, dents, cracks, etc. It turns on and seems to work properly. I am not an expert, the sound comes out, is responsive, etc. it has been standing still for many years. It may need a check or not. I don't know because I don't know how to test it thoroughly. Present its original cable in perfect condition and a very good padded and super resistant case is included. The manual can be found in pdf.
