Roland Jupiter-4 Late 70's Classic Vintage Analogue Polyphonic Synthesiser - 240V 

A rare opportunity to own a little piece of synthesiser history. (It sounds good too!)

The Jupiter-4 was first Jupiter synth released by Roland. It was among one of the first poly synthesisers with 4 individual voices which could be synced together for one fat monophonic lead, 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. (Vintage Synth Explorer)

Personally, we love the Jupiter-4 and have kept one in our personal collection.
