Roland Jupiter 4

“Roland Jupiter 4.

Just ridiculous bottom end – what a synth!!!
From classic era in analogue synth design.

Plenty about this online so no point spec’ing it here.
Just to say, Kent Spong has just given it a service…so all working great.
In very good cosmetic condition – end cheek scuffs as is typical on these early Rolands, and a couple of keys have a line across them (you can just about see in the pics) – but, generally in very good order.” Click here to visit listing on eBay

“In very good cosmetic condition . It’s been calibrated years ago . Tuning is good . Everything works as should . Sounds wonderful. It’s been upgraded with the latest tuning procedure that Roland put out . You still have the 4 tuning pots in the back of synth to lock it in even more . You can over drive the audio outputs which is very unique on this synth . The filters and envelopes can be very quick and snappy . Great pop synth . The chorus makes it sound huge . Sold as is . ” Click here to visit listing on eBay

Roland Jupiter 4 Project Machine

” Roland Jupiter 4 Keyboard. Was working about a year ago and went to test it and it’s not working. After opening the cover, it appears as though a green ground wire has come loose. Should be an easy fix for anyone who can solder. Missing the button for the protection button. Selling as is. I see these are selling around 8000 to 9000 refurbished so willing to sell for 5000. because you will have to do the soldering and clean it up and replace the missing button. Willing to negotiate any reasonable offer. ” Click here to visit listing on eBay

Roland Jupiter 4

“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 AVAILABLE.” Click here to visit listing on eBay

Roland Jupiter 4

“Recently purchased from and serviced by Oscidance. A classic Polysynth in good working order with a flight case and the bonus of solid walnut side panels which just need fitting / finishing. The original side panels are a laminate which always peels away and looks scuffed, so these are a really nice upgrade worth around £160.

The Arppegiator and ensemble chorus are great, and the warm tone, filters and additional 15v CV/Gate make this synth far more versatile and richer-sounding than any software version.These synths are becoming rarer and are selling for over £6k now, so at this starting price you could grab a great deal and if the JP8 is anything to go by, a great investment. The original instruction manual is also included as pictured. The serial number suggests that it features earlier Rev D BA662 filters, which tend to sound better than later models, but I am only basing that on the serial number as I have not opened it up myself. Collection only from Bristol, although you are welcome to arrange your own courier.”

“The Blue Tape is simply to protect the switches/appendages during shipping. MIDI Kit is Installed. Aesthetically, the synth is in good condition. Operationally, it’s in Excellent Condition. Everything works great, and the synth has been fully serviced. I will say, however, that I haven’t played it in 18 months. It’s been safely in storage.

There are obviously some dings in the wood. Printing on the Front Panel is very, very good. It’s all there. No real fading, except a bit in one spot (see pics). No cracks in the keys. There are some little black dots on the upper keys (top octave). I show in pics. These could probably be removed, but I didn’t bother to try because I didn’t care that much. I just want to be fully transparent.” Click here to visit listing on eBay

Roland Jupiter 4

“PHYSICAL CONDITION: Very Good – There are some spots of oxidation and scratches and blemishes, dulled finish throughout which are normal for a synth of this age. All controls, all keys, and all toggle switches are in great shape. Only one slider cap is missing on the cut/freq slider in the VCF section. The front-panel push-button switches are also in perfect shape. A mod has been installed located at the top left corner on the top-panel and consisting of 8 toggle switches, each with an adjacent 1/4″ jack. The wood side panels have a few dings but are still in very nice condition. The overall condition is very good.” Click here to search for synths on eBay

“Roland Jupiter 4 Vintage Synthesizer. Condition is For parts or not working.

Roland Jupiter 4. Lots of rust on the panels. Needs to be repainted around the lettering and then clear coated. It powers on but I cannot get any sound out of it so I do not know what else if anything it may need. It needs one slider replaced, the resonance slider. I bought it this way so I cannot tell you more about it. With that said, I am selling it as is with absolutely no returns. I think it would make a great restoration project for someone with the resources to work on vintage synths. ”

It looks and sounds amazing.

It looks almost new with just a few minor scuffs on the side panels.
I’ve played all three Jupiters and find the Jupiter-4 to be the best and most unique sounding synth.. it’s a warm, analog beast!

Roland Jupiter 4

“Classic Roland Jupiter 4 analogue synthesiser in perfect working order and good cosmetic condition.

The serial number is 105108, indicating a date of manufacture of September 1981.

A comprehensive review of the Jupiter 4, along with some videos can be found here: http://greatsynthesizers.com/en/test/roland-jupiter-4-the-golden-oldie/

Considering its age, this synth is in good condition. There are a few nicks and scuffs most notably to the side cheeks. One of the keys has a small burn and the paintwork is scuffed just below the LFO knob. All are photographed here.

This is a much loved and great sounding piece of kit used by 808 State, Vince Clarke, Depeche Mode,Thomas Dolby, Human League, Gary Numan, Tears for Fears, Stevie Wonder and Vangelis

The time has come to reluctantly let go of this and a few other pieces due to the demands of family life. I’ve been a semi-professional bass player for many years and can’t justify keeping a synth like this. But I’ll be sad to let it go.” Click here to search for synths on eBay
