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.

  • This unit has been used. 

  • Physically this unit shows some clear signs of wear. This is mostly oxidisation on the surface which has caused the paint to come off. The larger sections where paint has come off is from where the previous owner had stuck sticky tape to it. The side panels also show some wear, like peeling and nicks, most notably on the corners. There are no large dents, signs of spills, drops, amateur repair or parts missing. 

    The text is all still clear and legible and overall it is still a nice, vintage piece. The physical wear does not detract from the use, functionality or sound of this awesome synthesiser. Please see photos for further details.
