Korg Poly 800II with Moog Slayer Mod

“Korg Poly-800 mkII with “moog slayer mod” which apparently means someone installed a cutoff and resonance knob at their expense on top (and killed the pitch bend in the process). Not a big deal to me because I never needed a “pitch bend”, but it only seems to work for up/down mod, not pitch bend, maybe I’m doing something wrong. Everything seems to work fine otherwise, although the power cable is a little wonky if you move it around and a small scratch near the LED. I just bought this but sadly I can’t get it to work with my midi adapter to use a librarian. I have enough other synths to keep me busy” Click here to visit listing on eBay

Korg DW-6000

“I just had this serviced about 4 months ago at SWITCHED-ON in Austin Texas. New Battery and some of the number buttons replaced. This is in pretty great shape for a 35 year old synth. I reprogrammed most of the original presets using the enclosed printout of the preload program list. Really much easier to program than my DX-7. Sometimes the number buttons need to be pressed twice to enter the number or sometimes you press once and the number enters in twice – this has always been an issue with this model as well as the Poly-800 and DW-8000. Selling AS IS.” Click here to visit listing on eBay

Korg Poly 61

“Excellent vintage condition as shown in the photos. Hard case shown in the photos is included in the auction. It has scuffs and some oxidation on the metal corners and latches. There are no dents or damage on the keyboard itself that I can see. I am listing it with the condition as “for parts or not working,” because I have no facility to test it. It belonged to my late father who was a professional musician. I obviously can’t ask him about it now. So, AS-IS, FINAL SALE, no refunds or returns on this item.” Click here to visit listing on eBay

Yamaha DX7

“This DX7 has the E! Upgrade which gives you 10 banks of great sounds. Fully functional but comes with a few quirks. You’ll notice an end is cracked and button #29 has part of the face material missing. A couple buttons take a firm press to switch sounds/perform the function but all do indeed work. The keys feel great – I flipped the springs. What you see is what you get – no manual or memory cards, etc. Shipped insured with signature required in a well-packed box.” Click here to visit listing on eBay

Yamaha DX100

“Immaculate condition. One of the nicest I’ve ever seen online. Screen battery is dying therefore the screen is slightly dim. It’s one of those batteries you can find at local convenience stores. Other than that it functions perfectly with no issues and looks amazing.” Click here to visit listing on eBay

Yamaha DX11

“This is a great 80s-style synthesizer, and has some great sounds from the era. In good condition. New internal battery fitted, and sound and performance banks reset to factory defaults. The new battery is fitted into a socket making is simple for future replacement.

There is a scratch on the front panel, just above the 10/11 buttons (see photo), and some of the text has worn off from buttons 19-24 (see photo).” Click here to visit listing on eBay

Yamaha TX7

“Yamaha TX7 Sound Module (DX7 without the keyboard).

What can be said about the most important sound of the 80s?

The TX7 is a DX7 without the keys. 6 operator FM synthesis with loads of 80s sounds

Classic sounds including the ubiquitous Electric Piano.” Click here to visit listing on eBay

Yamaha TX-816

“Very rare mega FM synthesizer – this is 8 x DX7 voice boards (MK1 DX7, 16-voice, 6-operator FM each) in a single 4u rack. each module has independant midi inputs and balanced audio outputs, also there is a master midi input that can control all voice cards at once. It is 8-part multitimbral and 128 voice polyphonic (thats 768 operators/oscillators!) and can be used in any possible split / layer configuration.

This unit was recently serviced – several minor faults were repaired (dead led’s, faulty relays and switches repaired, psu serviced, new case screws) also all 8 batteries were replaced and fitted in holders for easy swap out in the future.” Click here to visit listing on eBay

Yamaha DX27

“In good condition with power supply,.

The DX27 is a full sized keyboard version of the classic DX100.

The DX27 / DX100 ‘Solid Bass’ patch is THE classic bass patch heard on many House and techno records in the 90’s.

Like all DX’s it uses (FM) Frequency Modulation synthesis. It is most renowned for its great analog bass sound (Patch #01) that is awesome for techno, house, jungle, and acid music styles; it’s very gritty, the bass tone with gristle!

Unlike the DX100, which has small keys and not easy to repair if faulty, the DX27 has proper full size keys with a nice action. 1000’s of free patches available online and easily transferred via MIDI sysex.” Click here to visit listing on eBay

Yamaha CS-5

“Excellent sounding synth with that gorgeous rich CS Filter. Kent Spong recently serviced this and installed a new voice chip, future proofed. I have the invoice to prove this. UK Voltage model.

It sounds amazing, fat and rich, very early Depeche Mode (it’s all over their Speak And Spell album) and is unlike any other synth I have owned where most sound the same, this is very unique.

As you can see in the images it is in excellent condition, never left my studio and I am a non smoker. ” Click here to visit listing on eBay

Yamaha FB-01

“This auction is for a fully-functional Yamaha FB-01 FM rack mount synth. In VG condition, other than some minor cosmetic scuffs on the top of the unit that are considered normal for a piece of gear that is 30+ years old! The last two photos show the extent of the cosmetic issues in detail. Cord is not split or frayed in any way, the unit powers up perfectly and all buttons function.” Click here to visit listing on eBay

Yamaha DX7 IID

“- Keyboard powers on, LED’s light up and LCD display works fine.

– I tested all keyboard keys prior to listing and they all work fine.

– When selecting between internal voices and cartridge stored voices, the “internal” button does not appear to be working. Since I do not have a data cartridge for this keyboard, I have not been able to test the buttons related to selecting different voices.

– The pitch-bend wheel (left most one) is loose and wobbly, but not disconnected and it still functions okay, it’s just too loose.

– I have tested the audio output to an amplifier and that works just fine. ”

There is a small slight blemish on the top right of the disk drive (as shown in photo) but other then that it is in great shape cosmetically (as shown in photos) This unit was just given a clean bill of health from the Sequential Circuits expert Greg Montalbano from Analog Synth Service in Berkeley and is ready to report for duty.” Click here to visit listing on eBay

Sequential Circuits Prophet 2002 and Sequential Circuits Prophet 2002 Plus

“This listing is for a Sequential Circuits Prophet 2002 Plus and a standard version Prophet 2002. The Prophet 2002 Plus is working and has the rare 1 meg expansion kit installed. 1 meg might not seem like a lot but it makes a big diffence from the standard version. The standard Prophet in the listing is not working, it turns on but does not have a disc drive. It is being sold as is, for parts. I took pictures of both with the top open to show the condition of the components. You will receive both Prophets, original Sequential 2002 manual and 2 Sequential pedals.” Click here to visit listing on eBay

ARP Omni 2

“PHYSICAL CONDITION: Very Good – In great condition. This is a vintage item so there are some signs of wear. Most of the slider caps are missing but all sliders are intact. The keys are intact and play fine but as seen in photos they are not entirely even, which is typical of these ARP synths. Otherwise, everything is intact, looking very nice, and ready for more use. The overall physical condition is excellent. WORKING CONDITION: Very Good – All keys are working though the lowest C squeaks a little when pressed rapidly, this is mechanical and not heard through the audio outputs. All push-button switches and their LED indicators are in perfect working order. All controls in all sections are working great. Output and control i/O are working great as well. Overall working condition is very good” Click here to visit listing on eBay

ARP Quartet

“I have owned this ARP Quartet from new and it has been well looked after and the condition of the wooden and metal casing and paintwork is very good for the age. It has always been stored in its original box but the box is looking very worn now. There is a small area of flaked off paint on the rear of the keyboard that is visible in one of the photos. The sound is very good but there are two issues that i can see that you might want to get sorted if you purchased the keyboard. The volume slider dosen’t adjust the volume any longer so i adjust the volume via my amp so i have never bothered to get it fixed. All sounds and effects work except for the celest on the organ section. The slider has come loose and the celest sound is permanently off. This might need a new switch fitting.” Click here to visit listing on eBay

I bought this about a month ago off of reverb. It’s not really my thing so I’d like to pass it along to someone else who’ll get more use out of it

Everyy works great, screen is clean and bright, all of the keys work and all ports are functional

The only defect I came across is the speaker will only work sometimes. Not exactly sure what causes this

Future Retro Mobius

“To be honest I never got to use this sequencer. I had some other projects come up with diverted my attention. However after talking to people who have owned one or currently own one they all were very loyal and had nothing but great things to say about the instrument. One thing I heard over and over again and part of the reason why it appealed so much to me is that its a straight forward sequencer. NO menu diving or confusing shortcuts to remember, just a fast unobstructed work flow without anything to stand in the way between you and your ideas. The unit is a rack mount and comes with the power cable!” Click here to visit listing on eBay
