Roland Jupiter-4 for sale. Meticulously overhauled!
We paid our tech for 30 hours of skilled labor required to make this unit nice and clean inside and out and working like new again. This work obviously adds great value to this instrument as it makes it better than most if not all others on the market.
In addition to necessary repairs, he did the following work to this unit:
Replaced all electrolytic capacitors.
Replaced all 4051 CMOS chips.
Removed all keys and cleaned key bed.
Removed plastic screws in power supply section and installed isolate washer and metal screws.
Replaced some IC sockets.
Added ground wire to reduce noise.
Cleaned and lubed faders, switches, key contacts.
Installed new battery.
An interesting note our tech added was that the serial number badge on the outside of the unit says sn85121x but inside says 79078x, no idea why. This JP4 is now working perfectly and sounding incredible. VIDEOS BELOW!
This is an excellent analog synth. It's one of the first polyphonic synths and has a similar sound to the Roland System 100 and SH series synths. It has most of the features you'd expect of a polysynth but its overall sound quality is terrific.
Warm, fat vintage sound - unison mode allows stacking of 4 voices per key and sounds huge. Ensemble (chorus) circuit and sweet analog filter. User programmable. Cool arpeggiator w/ random mode. LFO goes to high frequency for FM type sounds. The JP4 is great for pads, basses, noises, leads and all other types of analog sounds. Famous users include: 808 State, Vince Clarke, Depeche Mode, Thomas Dolby, Human League, Brian Kehew and Roger Manning of The Moog Cookbook, Kitaro, Ruediger Lorenz, Masterworks, Meat Beat Manifesto, Neruonium, Gary Numan, Elizabeth Parker of BBC Radiophonic Workshop, Nick Rhodes, Tim Souster, Spoons, Tangerine Dream, Tears for Fears, Tomita, Trans X, St. Etienne, Steve Winwood, Stevie Wonder, Vangelis, Yaz and more.
