Roland JP-8000

“There are certain patches that don’t seem to be working correctly but overall works good. Possible fix (from what I have read online) is a new capacitor. I am offering this at a discounted price and buyer will need to accept this as is. The unit needs to warm up otherwise you may hear some distortion when the volume is too loud, however once warmed up that goes away. ” Click here to search for synths on eBay

Korg Poly 800

“Battery compartment door is missing. It powers up intermittently and display shows “Load” when it powers up.
Cant seem to get a data dump of the factory sounds to load maybe it needs a new power adapter.
It has the Moog Slayer mod done with a 1/8” jack for cv control over the frequency knob, great for external control.
It has had the battery back up mod done so no need for the 6 c cell batteries. ” Click here to search for synths on eBay

Korg DW-8000

“Keyboard is in good condition. Has label taped on it for the midi in and out. Not sure if this is standard on these keyboards… Physically the keyboard looks pretty damn good in my opinion. Don’t see any major scrape or brakes. There are two open screw holes on the bottom. I do not know if this is for something to be added on or if two screws are missing. Comes with quarter-inch cable, MIDI cable, sustain pedal and stand. Keyboard stand has rust damage on it. Feels sturdy and has the pads on the bottom and top.” Click here to search for synths on eBay 

Korg Poly 61

“I have been the sole owner of this synth and have kept it in excellent condition. I have tested every slider, knob, pot, and key, and everything is fully functional! When I opened the case to inspect the components, I was pleased to see that it was nearly spotless. (See pics) The battery is old but in great shape and when I put it on the meter, it maintained a steady 3.3 volts. (Brand new it is rated at 3.6 volts.) All patches are intact and fully functional. The carbon contacts that sit under each key had oxidized with age, as would be expected, so they have been restored and all 61 keys work perfectly. I also connected the MIDI input to my Korg M1 and was able to trigger the Poly-61 as intended.

This sale includes the original manual, two MIDI cables, and one audio patch cable.” Click here to search for synths on eBay 

Yamaha TX81Z

“This unit is in very good condition, has not been on the road, and has spent its life in a smoke free/pet free/kid free home. I am the original purchaser/owner. I enjoyed using it, but never did use it heavily. This sat in the closet the last 20 years since I use a different keyboard. It’s in very good condition, minimal scratches or scuffs, and even still has the slide-out preset guide card. (see pictures)

I’ve plugged this in and tested a number of voices and everything appears to be functioning properly.

This comes with the original owners manual and some original TX-81Z pages I cut out of Electronic Musician magazine from 1987-88-89 ” Click here to search for synths on eBay 

Yamaha S30

“This is a 66 key version of the Yamaha Synthesizer, flagship model from around 2000.
Previously used for church. The strength of this product is that there are four sounds that can be saved and played simultaneously according to the four volume sliders at the left of the panel. (As you can I used tape to mark the settings that I used. They will be harmlessly taken off before shipping.)
The keyboard can also set ranges from which that sound will work. That way, a pad sound can be set for only the lower registers. Likewise the strings can be set to only play at higher registers. Also, there is of course, other modulation: reverb, chorus, pitch shift, etc.

That’s basically what I use.
The piano comes with a FC-4 sustain pedal which was separately purchased and in Like New condition.
The piano also comes in a gig bag. Although not very strong it is still useful.
Unfortunately this does not come with the power supply. The power is standard with a few of their other models which I’ve also played. You should be able to find this on the internet.” Click here to search for synths on eBay 

Yamaha SK50D

“This is an absolute monster.., a rare and great machine… built like a tank!. You probably know this if you are looking.

The bass will rattle windows. The organs give very good Hammondesque pads. Poly synth can be layered with the string section – and even the organ. But it is the mono synth that I like best. That can be layered with the bass for amazing deep and squelchy bass lines.

Its a library picture, but mine is in excellent condition – especially considering it is about 37 years old!. I have the case (that it is semi built into) and a Z stand.” Click here to search for synths on eBay 

Yamaha DX27

“This synth is in great working condition and shows no signs of giving up after so many years. Built very solid. Replacement (not original) power supply is included.

I have played this a little for the past years or so and found no issues. Pitch and mod wheels, display, headphone jack, patches all work.” Click here to search for synths on eBay 

Sequential Circuits Pro One

“In good used condition Includes flight case an manual (well used)
Keyboard is fully working however a couple of knobs are a bit noisy when being turned and synth could do with a service as this has never been done. For this reason I have started the auction with a lower price because the item could do with a service.
Synth was bought not long after they came out and is in very good condition with no scratches to casing.
Has been stored in flight case for past 10 years. “ Click here to search for synths on eBay 

Sequential Circuits Prophet 600 Project Machine

“NOT WORKING! Will not turn on. I have owned this synth since it was new for my home studio. See pics for superb cosmetic condition. Never gigged, never left it’s climate-controlled, smoke free environment. I do not know what the issue is, but before it went into storage I tested it and found several keys did not play. This was always played thru MIDI from my DX7, so I didn’t notice this before that. Hopefully someone familiar with these can bring it back to life-these instruments have a wonderfully rich sound and deserve to be played.

It will ship with the original Owner’s Manual and a HYBRID flight case that I had made for it when new.

The Prophet-600 is a 6-voice polyphonic analog synthesizer with a 5-octave, 61-note (C-C) keyboard. Each voice consists of two VCOs, two VCFs, and two VCAs. Each of these components has its own independent ADSR envelope. Each Prophet-600 voice uses 2 sets of Curtis Chips for its architecture.”

Sequential Circuits Prophet 600

“Classic analog synth with amazing fat leads, lush pads and filter sweeps from early-mid 1980s, with MIDI, comes with hard case. Synth has some scratches and dings on body and wooden end pieces (see pics) which you would expect from a 30+ year old keyboard.

The high A key was cracked but repaired and fully functional, just shows some discoloration where it was glued (see pic).

I installed a brand new membrane keypad and LED display (an item that original component frequently fails on this model) about 15 years ago. Now operational, better than original.

Sequencer appears to work, has a program in there from a previous owner, but I’ve never really fiddled with it to verify its functionality.

I played this keyboard for years in a gigging/recording band and loved it. The nature of this beast is quirky–there are occasional hiccups and glitches that happen when you dial and switch–all good stuff–but sounds and knobs are all fully operational. Remember, this thing has a fully analog audio signal path, but the voltage controllers are digital. Best of both worlds!”

ARP Avatar

“For your bidding pleasure: 1977 ARP Avatar Vintage Guitar Synthesizer with Pickup / Cable / Footswitch / Manual / Promos. Used but not abused, some sliders are a bit ‘sticky’ but work. Unlike most Avatars this one works great, sounds great and tracks surprisingly well (better than any I’ve heard). It’s important to find the sweet spot when mounting the pickup. You get the Avatar, original pickup, original pickup cable, original footswitch, original manual, original service manual with fold out schematics, and original promo literature with flexi record. Guitar not included. “

Wiard Waveform City

“Very rare Wiard 300 series Waveform City analog synthesizer module Model 342. Long out of production, and according to Wiard, it will never be produced again. Excellent condition. This module has been upgraded by Wiard with Bantam (TT) jacks. It’s a huge improvement. The difference in quality between 3.5mm (1/8”) and Bantam is the difference between plugging into an iPod and a professional studio patch bay. “

Waldorf Microwave XT Project Machine

“Selling my NON-working Waldorf XT. It lights up intermittently but does not sound. This is the model that is expandable to 30 voices per the photos of the inside board. It looks like someone plugged it in with the wrong power supply or something as seen by the photo near the input. From what I have read this seems fairly common and repairable but i make NO claims that it is, therefore selling for parts only. I do not have the knowledge or expertise to attempt repair. Sold AS-IS. Let me know if there is anything else you need. Selling it with the non-original power supply. Potentially the problem exists there as well. When I plug it into another correct amp power supply it lights up every time normally but the led characters do not show anything. Otherwise, there are some knobs that the top caps are missing and a minor bend near the lower left rack hole. “
