“Moog Rogue Synthesiser.
I’ve had this synth since the mid eighties and it’s never been gigged, home use only.
Perfect for soaring lead sounds or for thumping bases and is quick and easy to set up.
Still in really good condition for its age.
Fired this up today and the sound is stable. The only small issue is a little bit of fader noise on the AMT, OSC1 and OSC2 but this is only when sliders are moved and I’m sure this will be easy to rectify.
It still has original MOOG power supply and the original packaging although this is beginning to show it’s age now. Also included is an owner’s manual which is in good condition which I received from Moog back in the eighties. ” Click here to search for synths on eBay

“Up for sale is a rare JHS SD-1 Pro-Rhythm Analogue Drum Synthesizer from the late 70’s from John Hornby Skewes (JHS).

The item has just had a fully service so works perfectly and was from my collection which I am in the process of selling.

The SD-1 is a battery powered drum synth with sound shaping controls and a rubber pad which, when hit, triggers the analogue circuitry for an infinite variety of possible sounds from deep bass to high pitches to sweeping disco tones.” Click here to search for synths on eBay

“Hello!

You are viewing a Roland D-50 being sold AS-IS or for PARTS.

Here is what I know: I purchased unit on eBay two years ago, wanting a vintage D-50. The unit worked perfectly on arrival and for about six months afterward. Then the unit would only play sounds on key release. This problem is known and usually is indicative of a bad keyscan board or connection to it. If you are handy with electronics, it may be an easy fix if you can track down the parts. I have searched for months here looking for a complete keyscan board to no avail.

The unit was cleaned (previous owner had two-sided foam tape and stickers all over unit) and was working perfectly. Keyboard itself feels Roland-luxurious as original. No dents/dings in the chassis, however there are missing screws on the bottom panel (indicating it was serviced before) and the rubber feet/screws are missing.

The unit DOES play perfectly via MIDI, is capable of sending/receiving sysex, all buttons are functioning as well as MIDI in/out/thru. All audio/phone outputs working. Display is about 70% brightness from new, no bad elements on LCD. Joystick functions perfectly. Sound (via MIDI) is original quality.

Will ship packed in gig bag (no charge, just for protection) and carefully wrapped. I have three road cases, if you want one, just contact me after the auction and pay the extra shipping. Unit is heavy, hence the shipping charge. ” Click here to search for synths on eBay

” You are looking at a Roland MKS80 Super Jupiter and the MPG80 programmer. I purchased this synth in 1987 and have owned it ever since.
At that time I had finished a touring music career and was beginning a career in film scoring and theater sound design. This synth has never been gigged live. It has been used in a number of my small home studios over the years only. I used the synth for my work for about nine years until about 1996 when I completely stopped making music and started a small business. The synth sat unused in a box until about 2012 when I began to dabble in music again. It basically sat unused for 16 years.
I have just replaced the dust protectors for all of the sliders in the MPG-80 and completely cleaned the sliders internally as well as the PC board. It is like new at this point. The new dust protectors are a bit stiff and will eventually wear in. You can feel the fibers of the material rubbing against the slider shafts, but the actual sliders are extremely smooth and function like new. They were completely tested before replacing the dust protectors. The manufacturer of the dust protectors assured me that the material will wear in with some use. It’s rare to find an MKS80 and MPG-80 combination with this kind of low mileage on it.
The current pandemic situation has left me no choice but to sell some of my equipment in order to pay the bills.
I will include all of the factory racking hardware for both the MKS80, and the MPG-80, the original user manual (both the MKS80 & MPG80), the C64-C memory cartridge, and the original programmer DIN cable that connects the MKS80 with the MPG-80.
I will ship the purchase in two separate boxes. I want to be sure that I can safely protect the sliders on the MPG80.” Click here to search for synths on eBay

“Buchla – 272e (4 stereo F.M.tuner) analog synthesizer module. Condition is Used. Shipped with USPS Priority Mail. This module also requires some special circuits built into the “power boat” for the module so that an antenna can be connected. If you are super-handy with electronics and/or ground loops, you may be able to fashion and antenna to your liking that doesn’t require the additional adaptations. But because these adaptations are required, we should talk about how you would like me to disassemble and convey those parts (which will take longer to handle and ship than just selling the module by itself). If you just want the module and plan to deal with antenna on your own, I’ve enabled the “make offer” feature.” Click here to search for synths on eBay

“Vintage 1970’s ElectroComp EML-200 Modular Synthesizer, in blue.

EML 200 is keyboard-less, making it more like an Expander module designed to interface directly with other EML equipment. Most notably, with the Model 300 manual controller which offered a 4×4 key matrix, pitch knobs, and an oscillator with envelope generator and VCA of its own. Today, you can use the 200 with analog synths other than EML with the properly modified CV/Gate connections and converters (its oscillators are a non-standard 1.20v/oct).

It does power up and the red power light is on in the pictures.

Overall in very good shape, with some scratches on the sides and back panel.

I did have them checked out, and had the necessary repairs\cleaning done to make them functional.

The unit was cleaned and tested. All the jacks, connections, and potenciometers were cleaned and checked.(Per the repair technician)

The sample and hold were repaired on this unit.

All original.” Click here to search for synths on eBay

“Akai AX60 Analogue Poly Synth.
In excellent condition.For it’s age it looks really really good.You wont find one better looking than this!!
It has never been gigged and has just been used in my studio.
It has developed a problem which is quite an easy fix if you know what your doing or want to get it serviced.

The synth was working perfectly a few days ago and the next day i turned it on and all the sounds had vanished.There are still sounds but not what i would call useable.

Either a new battery is needed or one of the voices has failed.Im no expert and i dont have the time or the patience to get it fixed.” Click here to search for synths on eBay

“ARP 2600 Model 2601 Synthesizer for sale. This unit is one of if not the nicest black and orange 2600s we’ve seen. We bought it from someone who owned it since it was new. He rarely used it, and this is quite obvious from looking at it. (See photos)

One of the other 2600s we’re selling is also here on ebay for a fraction of this one’s price, so if you’re not looking for a 2600 in museum quality condition, you may be interested in that one instead. It received the same meticulous electronic restoration and future-proofing we’ve been doing to our 2600s for a long time now.

This unit was disassembled, cleaned inside and out, meticulously serviced AND FUTURE-PROOFED and fully and repeatedly tested by vintage synth specialists with decades of experience (us). This process required 31 hours of skilled labor. The result is an ARP 2601 that is much better than the rest.

This unit is working perfect, is ready to play, and will hopefully outlast all others.

In addition to any repairs, we did the following work to this unit:

-Fully disassembled, cleaned inside and out.
-Power supply rebuilt: new capacitors and trimpots.
-All tantalum capacitors replaced (these are a common source of failure in ARPs).
-ARP typically installed rubber gromets in between the reverb tank and wooden enclosure of their 2600s. For some reason, there were no gromets installed in this unit, so we installed new ones.
-All sliders and switches cleaned and lubricated.
-Molex connector terminals replaced for better connection.
-Keyboard fully rebuilt: removed and cleaned all keys, cleaned J-wires, removed and cleaned bus bars, replaced rubber bushings.
-Replaced Cinch-Jones keyboard connector socket.
-Recalibrated.
-Replaced some metal hardware (screws, jack nut, etc).
-Burn in test.
-Multiple systematic tests of all functions.

Earlier revisions of the 2600 are notorious for having their modules sealed in black epoxy. This late version 2601’s circuits are all open, so if a component ever goes bad, repair should be easy.

Apart from a little rust on the metal hardware on the outside of the case (which we see a lot) and 1 or 2 tiny imperfections, we feel this unit looks immaculate. But please take a good look at the many detailed pictures posted here to see for yourself. We have 45 detailed photos of this 2600 but eBay only allows us to post a small number of photos.” Click here to search for synths on eBay

“Roland JD 800. Condition is Used. Collection in person only.

My beloved JD800 in need of some love.

Although it turns on, patches and memory intact and is perfectly useable as a sound module, 13 keys are not working. 2 are sticky and the rest are in responsive. It most likely needs a new contact strip or such like.

I’ve run the diagnostic test and all faders work fluidly with exception to the cut off that jumps in increments of 10. Most likely needs a good clean!

There’s a low mains hum from the outputs not uncommon for a synth this age (I bought it in 1996) it’s never bothered me and never been noticed on any recordings.

These machines when services go from £900 + so could be a great project for someone willing to rework the keys and cut off slider. Otherwise a great board for that authentic 90’s sound or worth sampling!

It’s a very heavy beast so please come and collect it!”

“Digital Interface Buttons: Working condition but we do not have a manual
We can not guarantee that absolutely every function is working the buttons all seem to change something but combos of buttons or multi layer functions we did not check
we just did a quick check over so please bid accordingly

General Physical Condition: Light general wear (surface scratches/dings – will need a little clean up but otherwise intact)

The Case: Older Used Condition (general wear) Case is a hard case and has wheels on one end but no handle.

The Stand: If pictured, not included.

Power Supply: Included – it will need a cartridge (we used a test cartridge to play test it but one is not included).

Additional Info: This synth has a great hard case – it even has wheels on the bottom! One key sits slightly higher than the others however it plays just fine. Known for the crisp, bright, and glassy tones that stood in stark contrast to the warm analog tones of the era, the DX7 was the first truly mainstream digital synthesizer.”

“EML ElectroComp 101 Keyboard Synthesizer in very good condition. I was recently lucky enough to grab an EML 100 and unfortunately can’t keep both, so my 101 is looking for a new home. Functionally it’s wonderful, but a little rough around the edges cosmetically. All can be seen in the pictures, but the handle is frayed, some dings and chips in the case, and there are some marks on the face where someone decided to “save” their parameters. All in all, she’s an amazing piece of electronic music history, and as a collector and enthusiast, I’d love to see her go to someone that’ll value it as much as I do. ” Click here to search for synths on eBay
