Roland JD-800

” Used Black Roland JD-800 Progamable Synthesizer keyboard with cord and cover. Condition is “Used”. Shipped from US, one owner ever.

It used to belong to my father who passed away on February 1st. I don’t have the space to keep it sadly since it’s rather bulky and I already have another keyboard.
It turns on just fine and all buttons work but after testing it it does seem to have an issue with connecting to an amp but nothing a repair shop shouldn’t be able to fix.” Click here to visit listing on eBay

“ROLAND JD-800 Digital Synthesizer Spares / Repair. Cosmetically in good condition and working. The parameters occasionally self edit – easily fixed with a clean and lube of the fader.

This has had the common red glue issue. Some keys sticking together and traces of red glue having leaked on them. Some Kenya also not triggering. I bought with the intention of restoring this but I think it’s beyond my capabilities – this plus it’s taking up room on my keyboard stand which I need for a new synth.” Click here to visit listing on eBay

“Roland JD 800 for sale
Comes with an extremely solid touring flight case
“Voice Crystal” ROM card included

I have had the keyboard serviced at start of 2020 (keys were fixed so there shouldn’t be any glue issues in the future etc which these keyboards can suffer from). Since then it has been kept in the flight case and only used once or twice in a dry home setting before being stored back in the flight case.
It is an excellent synth with a ton of sliders and controls.
I am only selling as I do not have a studio, and it is too large for me to set up at home.” Click here to visit listing on eBay

“Roland JD 800 in excellent condition- this is a beast of a synth and sounds analog even though it’s digital. I’ve had it for over 5 years and it works flawlessly. I got the red glue issue fixed. Basically when these synths get very warm in summer for example the glue can leak and stick the keys so they don’t work. I’ve fixed this issue so you should have no further problems.”

“This synth is in excellent condition. The keys feel great and are responsive to velocity and aftertouch. All sliders are smooth. LCD screen is fully functional. MIDI works well. All jacks work and sound great. The top menu button needs to be pressed harder to make it register, but otherwise all buttons work perfectly. There’s no issues with red glue under the keys. I was having trouble with the retractable cover on the sound cards. I’ve taped them back and haven’t had issues since. There are a some light scratches, but nothing unexpected for a synth this age. I included a photo of where it’s most affect on the back corner. It was recently serviced and cleaned. ” Click here to visit listing on eBay

“The marked keys need repair as they are dead and one plays loud and a couple others are intermittent.

For sale is a Roland JD-800 Synthesizer. It works great except for the marked keys being dead. One of the marked keys plays really loud. A couple others are intermittent and the rest are dead. I noticed that the Bias Point slider is stiff but it seems to be working fine. Also i noticed that when i press around 8 keys at the same time i hear a little bit if static for a second. This may be normal. Please see the pictures and note the snall stains on the painted plastic as well as the scratches. The internal battery needs to be replaced as i saw a message about low battery voltage when i turned it on.
Includes a Roland style power cable.” Click here to visit listing on eBay

“This synthesizer will never have the red glue issue. It has just a few minor scratches that can seen mainly on the right end cap.There are no issues with any of the buttons and sliders. I’ll give the key bed a 7 out of 10. All of the keys work but a couple of them give me a slight click sound when released quickly. I’ve had this synth for years and I have decided to sell it because I now have the module version of the JD800, the JD-990.

“this is used roland jd 800 keyboard I got this keyboard from a studio .I got this kyboard without keybed .the previous owner use this keyboard as midi .I just put the Yamaha keybed just for cosmetic.so basically you need original keybed from roland to work it as a keyboard .but you can use it as midi.” Click here to visit listing on eBay

“Selling a Roland JD-800 in pretty nice shape! This synth works as a module, but the keybed does not work anymore. The failure-prone flexible ribbon connector is shot. However, I did spend three whole days removing the infamous red goo and re-gluing the key weights so the next owner doesn’t have to burn their hands with lye solution like I did. 😉

It’s up to you to decide what you’d like to do with it next. I don’t know if replacement keybeds or other parts are still available from Roland, but you could also just use it the way it is as long as you don’t mind having a controller nearby.” Click here to visit listing on eBay

This synth has been lovingly looked after and used on many recordings over the years. Unfortunately it has developed a fault that I’ve been unable to repair. I’ve also had someone else look at it locally who purported to be a specialist synthesizer repairer, but as it turned out they didn’t really know any more than myself about the LSI digital & analogue electronics employed in a synth from this era.

Having wasted my time and money trying to get it repaired locally, I’m not prepared to further send it, or drive 100’s of miles to try to get it fixed. I’m sure that it must be repairable by someone out there with the requisite abilities. Anyway, reluctantly, I’ve decided to put it up for auction here offered for spares or repair.

Here is a description of the fault;

a) 1) The on-board diagnostics report that the PCM ROM’s 1, 2 & 3 are “NG” (= no good).

(Note: all other diagnostics pass and complete correctly)

b) 2) Only spurious artefacts (from any patch selected) are audible when the keys are played, (or when external midi note on/off are received).

c) 3) When selecting a different waveform using the WG rotary encoder (for most of the patches), the waveform reference in the display appears to be corrupted.

d) 4) It appears to me that the fault is probably on the main board.

I have managed to verify (by selecting those patches which output enough spurious sound to work with) that apart from the above anomalies everything else appears to be functional. All sliders, knobs, buttons and the bender appear to work and display correctly. All midi functions; note on/off, sysex, bulk dump, external editing, etc. work correctly both in and out. All of the on-board effects function and display correctly.

As can be seen from the pictures, the synth is in excellent condition for its age, with just a few scuffs here and there. The top panel is in great shape and all sliders, buttons and knobs are intact. There has been none of the dreaded “red glue” on the move and all of the keys are intact.” Click here to visit listing on eBay

” Roland JD800 in excellent condition. The keybed has been restored/cleaned to remove all traces of “red glue” and the weights re-attached (quite a job!). The visual condition is excellent 9/10 I would say and couple of small marks. All working as it should all bar the aftertouch (which has never really worked on any JD800 I have owned!).”

“Roland JD 800 Synthesiser. Great Condition. 240V.

Welcome to my auction.

This is a stunning looking and sounding synth!

The synth is in fantastic working order. I’ve thoroughly tested all the main controls and can find nothing wrong except a bit of crackling on the volume slider when moving around at high volume range. This doesn’t affect the operation in any way and is easily fixed – I just didn’t want to open the machine just for that.

The keys are responsive and work perfectly. They spring back as they should and are level, unmarked and undamaged. The touch-sensitivity and aftertouch are working fine.

All buttons, sliders and knobs work perfectly. The displays are clear and bright and all LED’s light as they should.

The case is good for the age. There are minor marks which I’ve tried to show in the photos. One rear lower corner has an area of missing plastic (this happened before my ownership) as shown in photo 11. It doesn’t affect the usability in any way and is the only damage of any significance anywhere on the synth. Please see pictures as they form part of the item description.

The synth comes with the original user guide (slightly marked front cover) and a receipt for a service it had in 2015. This service included the cleaning of all faders and an electrical safety test. There’s also a power lead.”

“This Roland JD-800 looks to work; did some quick testing of the oscillators, filters, envelope generators, and VCA’s and didn’t see any problems. You can see the orange instrument lights and LCDs all light up appropriately. All knobs and sliders seem to work just fine, but many of the piano-keys currently stick together, a few don’t go down at all, and some don’t sound. This is due to the Roland factory piano key-glue softened while it was otherwise being safely stored; the glue just simply breaks down and the weights refasten themselves onto the bottom of the keybed or the keys next to them. The case has some cracks in it near the system keys (see photo) and a chunk has broken out. All the buttons around it appear to work fine. I hear a loose piece of plastic rattling, but haven’t found it when I opened it up.” Click here to visit listing on eBay

“Up for sale is a Roland JD-800 Synthesizer. The classic Roland JD-800, from an era (the early ’90s) when the analog revival had already started, and Roland implemented a digital synthesizer with analog-style controls. The sound is classic late 80s/’early 90s Roland – crystalline, powerful, with quality effects. The patches feature some great evolving pads, powerful basses, moody electric pianos. quasi-analog brass, lush strings, and much more. The JD800 can be expanded via PCM and Data Cards.

Originally purchased from an Ebayer in Japan, who had completely gone through this synth with a fine tooth comb. The infamous red glue issue was repaired and a brand new key contact strip was laid down, all red glue removed from the keys, and all weights were epoxied back into the keys. I attached a photo to show that. All sliders were completely gone through and cleaned as well and they slide like they would have when it was originally selling at music stores. All touch tact switches were replaced too. When it arrived in the US I went inside and de soldered the leads on the transformer from the Japan 100v and soldered to the US standard of 120v, eliminating the need for a step down converter. There is zero scratches, blemishes, or dings on the metal chassis and plastic parts. Bottom panel is flawless other then the shadow from the keyboard stand it was on and has been meticulously cared for including dust covers when not in use as well as being in a smoke free environment. Due to the size and weight of this synth please allow one additional day for packaging before shipping.” Click here to visit listing on eBay

“Roland JD-800 Synthesizer Works Fine Needs A Little TLC. Condition is Used. As you can see a few of the buttons have been removed for God knows what reason. So those are gone. The far right key is the only key with an issue and it’s a minor one no pun intended. The key probably needs a spring replaced. Also a few of the metal bars underneath the keys are missing.” Click here to visit listing on eBay
