"A legendary keyboard that needs very little by way of introduction! This vintage Jupiter 8 is in very good overall condition having spent most of its existence in a temperature controlled studio. The serial number is in the 410000 range, indicating that it is a later model, which may be important to some users and collectors. This keyboard contains most (if not all) of the factory mods and improvements made to the Jupiter 8 line over the years, including changes in D/A bit rates, LED displays, and the addition of a DCB port. No other modifications have been performed on it since it emerged from the factory during the heady days of the 1980s.

It is a monster of an instrument and I have found that modern day plug-in emulators really do not do it justice. The Jupiter 8 has received outstanding reviews since its introduction and has a huge cult following, especially on the vintage market.

Cosmetically, this keyboard is remarkably clean considering its age. There are a couple of surface scratches on the finish, and a few of the sliders are slightly bent. I'm sure that a handy individual could have them straight and true in mere minutes. There is some discoloration underneath the clear protective plastic plate covering both LED readout indicators that seems to be paint or finish related. It is only present where the plastic cover is mounted to the steel surface of the unit. It does not extend into the viewing readout area of the display. Please refer to the pictures above to view it. Knobs, switches, and buttons are all in good working order. The keyset on this instrument is straight and in very good shape. Overall, this keyboard is a fine example of the breed.
This auction includes the Roland Jupiter 8 keyboard that will be shipped in a brand new ATA Kent road case complete with back casters for easy maneuvering. Sorry, the manual is not included but fortunately, the web contains virtually every shred of information and detail about this keyboard!"
