Roland Super JX

“Roland SUPER JX JX-10 polyphonic synthesizer working AS IS. Condition is “Used”. This is the roland jx 10 tested and working comes with power cable and rom cart. Reason why it is as is. Is because of the missing keys and condition of the unit it powers on sound comes out of the speakers but the menu diving for peramiters is not for me. So if this is the synth for you enjoy . and happy playing!!!” Click here to visit listing on eBay

“Synth is in good working order. Everything works, but clearly some of the buttons could use a cleaning on their contacts as a few of them need a little extra push or wiggle on the button press (doesn’t effect functionality). Key contacts have been cleaned and work flawlessly.” Click here to visit listing on eBay

“Roland JX-10 Polyphonic Analog Synthesizer. Condition is Used. Local pickup only.

Don’t have all the necessary tools and time to fully commit to refurbishing this awesome synth. Was gifted to me but I’m not exactly in the market for these models.

The main issues I’ve encountered are

11 dead keys: either sometimes respond or not responding at all (Marked keys in pictures provided).
Buttons: Heavy force or repetition for some buttons to finally respond or don’t respond at all.
LFO Bender: Does not seem to add effect, pitch bender (left &right) works great.
Aftertouch: Slider for said aftertouch also, does not seem to add effect.
Cosmetics: Paint job is damaged considering its years.

MIDI has not been tested but inputs and outputs seem to work great.

Original power adapter not included, using a makeshift adapter.” Click here to visit listing on eBay

“This JX-10 is in good condition for it’s age. The display coil needs to be replaced (available on eBay), and this causes one character to have all segments fully lit and another character to be missing (see pics). The lowest key has apparently been replaced by the previous owner so it is whiter than the others. Other than that, the unit is fully functional and looks pretty good.” Click here to visit listing on eBay

Roland Super JX with Roland PG-800

” The synthesizer is in excellent physical and operational condition. Every control surface works as expected, there are no dead keys, and audio out to my test monitors is crisp and clean.

The programming console is in excellent operational condition. All its sliders work and have their handles. All the knobs turn easily.

My living and work areas are smoke-free, so this equipment should be reasonably hypoallergenic. ” Click here to visit listing on eBay

There is a slight scuff mark on the top left, see picture. It still has the original battery.

Includes manual, music rest, and M-64C cartridge.” Click here to visit listing on eBay

“I am the ORIGINAL OWNER of this Roland Super JX-10…it was my first synth ever purchased and I bought it brand new in the 1987. The synth, cartridge, and power cord are all original. This is one of the most versatile and unique synth’s I’ve ever worked with…it’s fully functional and in great shape (only a few cosmetic scratches on the side and back).

Because of it’s age this unit is being sold AS IS, but I recently went through it and it everything appeared to work just fine, I’ve never had any issues with it. ” Click here to visit listing on eBay

jx10 “Roland Super JX-10 in good condition – with one known issue: The LFO direction on the Pitch/LFO controller seems to be broken. It’s hard to see in the photos but the controller is actually recessed a little into the cavity. The pitch control still works (left and right) but the up direction for the LFO control does not. I don’t have the expertise to look into it, but hopefully it’s a simple fix for someone who knows what they are doing.” Click here to visit listing on eBay

Roland JX-10

kx1- “This is a beautiful sounding synth that you’ll recognize from late 80’s movie soundtracks. It has the new Vecoven 3.03 chip that adds an arppegiator, on-the-fly tweaking of assign-able parameters, and completely overhauled sys-ex implementation!
There is one cosmetic flaw: before I had it, a previous owner put a cigarette down on the front panel by the volume slider (!?) and melted the panel there. This doesn’t affect performance whatsoever.
All keys play–there was a couple that didn’t when I first got it; I opened it up and cleaned the key contacts and now they work fine.
The aftertouch needs to be serviced as well. Keyboard plays great without it, but since it’s a desirable feature, it’s definitely worth doing. I just haven’t gotten around to opening this up again. There are “how-to” videos on servicing the aftertouch; basically removing the keys and cleaning the oxidation off the contact strip. Only real investment there is time.
Since this is a vintage electronic instrument, I’m selling it as-is.
Sale includes JX-10 synth pictured, M-64c cartridge, original power supply, spiral bound manual and keyboard dust cover (last three items not pictured).” Click here to visit listing on eBay
