Roland Jupiter-4 for sale. Meticulously Refurbished.

This unit was fully overhauled, sparing no expense, a process requiring 26 hours of skilled pro vintage synth tech time. This included future-proofing measures that will hopefully extend its life way beyond others. The value of this labor plus parts is of course factored into its price. This is a rare opportunity to purchase a gorgeous JP-4 that's working perfectly and that should make its next owner very happy.

In addition to repairs, the following work was done, much of it preventative. It's likely I left out some work, but rest assured, we did a thorough job and did not cut corners like other sellers almost always do, as we wanted this jp4 to work perfectly and hopefully outlast lesser examples. 

Cleaned unit inside and out.
Checked / reflowed solder joints.
Rebuilt power supply for longevity.
Replaced 40 pin IC socket cv gate board to ensure good connection.
Replaced 40 pinIC socked main PCB to ensure good connection.
Replaced battery (3v lithium)
Cleaned and lubed all pots and switches.
Replaced electrolytic capacitors for longevity.
Replaced trimpots from all 4 VCOs for ease of tuning.
Recalibrated VCOs and filters.
Adjusted envelope balance for all voices.
Installed new power cord.

Don't miss your chance to own this beauty. As of now, this is the only one in stock, so once this one's gone, it could be a long time before we offer another.

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.

They fit super snug and the quality is way better than price suggests.
Size: For BMW E46 2002-2005
They came in wrapped very well in foam and bubble wrap. They felt sturdy and the matte finish was satisfactory. They needed quite some pressure to snap in but when they did you could tell they weren’t going anywhere. The fitment is perfect and it looks great. If the stubs in the car where the grille clips attach are in tact you shouldn’t have a problem. Don’t be discouraged by the negative reviews.

Good value for the money
Size: For BMW E46 2002-2005
The matte is flawless and looks pristine & super easy to install. It does fit and it’s a good enough fit for a daily driver; however, it’s not a flawless fit. It’s off by maybe a 1/16th on the inside corners. It’s amazingly close despite the price point…would definitely recommend.

VERY poor materials and fit for E46, WILL FALL OUT
Size: For BMW E46 2002-2005, Size: For BMW E46 2002-2005
This part resembles the original, but not enough. It is both too big AND too small, depending on the dimensions. It's too small from top to bottom, and too big from side to side. The locking tabs don't get close enough to lock (see pics) because there is too little clearance. Viewing from the front, the outer top corner is so far out (see pics) that the most important tab cannot properly lock in, causing the grill to drop out into my hand (or the ground, if I wasn't there to catch it). The grill also is missing some important curves to follow the shape it is supposed to fit into. It also wasn't matte black as ordered. It looks like it was spray-painted, but I can't be sure. it is made of VERY brittle plastic, and the locking tabs are VERY small and flimsy. I wouldn't expect this part to survive a month or two before blowing away in a medium breeze. One positive is that there is a relief cut to allow the hood safety catch handle to move fully upward without interfering with the plastic grille. That one positive has a lot of making up to do, and there's no way it can do it. Add to that that the seller included instructions for a car fifteen years newer than the model advertised on the item page, and we have a complete failure. But don't worry! I'm sure the seller will probably delete the listing and make a new one so they don't have to have this honest review attached to it.

Quality grills for e46 BMW
Size: For BMW E46 2002-2005
No reason to buy replacement grills at the dealer or even at an auto parts store. These are great quality for a fraction of the price...and you get both sides. Highly recommended if you have an e46 and the grill plastic has deteriorated and is loose. These grills are thick and robust. I like them better than the original. Fit is snug but they look great.
