ROLAND JUPITER 4 recently overhauled - fully working except 3 presets: funk clavi, piano, sax.It has 2 little dents on the top and some scratches on the keyboard (that can be replaced with a new one).IF YOU ARE INTERESTED IN, I CAN SEND OTHER PHOTOS.FOR THE SHIPPING COST, IT DEPENDS ON WHERE YOU ARE.The Roland Jupiter-4 (JP-4) was an analog synthesizer manufactured by the Roland corporation between 1978 and 1981. It was notable as the company's first self-contained polyphonic synthesizer, and for containing digital control of analog circuits (termed "Compuphonic" by Roland), allowing for such features as programmable memories and voice assignment modes.It was among one of the first poly synthesizers (4 individual voices which could be synced together for one fat monophonic lead), it had a pitch wheel that could be assigned to the VCA, VCF, VCO or all together, there are 8 memory locations and a cool arpeggiator - the arpeggiator can be heard in the Duran Duran classic, "Rio". It also has a very slow LFO for those ever-so-long filter sweeps.JUPITER-4 COMPUPHONICKEYBOARD
