“Beautiful Korg Poly 800 with only a few minor scratches on top, marker on bottom and missing a few screws on the bottom. I tested it with an aftermarket 9V power cord and it powers on and looks magical however it needs to be serviced. I could only get a few sounds out of it, most of the time I could not get anything. This is being sold for repair. Includes vintage Hybrid case in good condition with wear, missing corner guards” Click here to search for synths on eBay

“I am selling my rare Korg MS2000R synthesizer. I used it with Korg Kontrol 49 keyboard. It works great, especially with other Korg keyboards, midi keyboards, etc. Its an external synthesizer compared to the synthesizer keyboard of the same brand. I will include the original power cord. Only problem is on the back, where the synthesizer can be opened, it seems as if its been attempted to be prided open, you cant see the components and it doesnt affect the functionality. Thanks!” 
“This is in very good condition and works as it should.
“Yamaha SY-1 Vintage Analogue Monophonic Synthesiser (1974) Superb!” 
“I am original owner of this Vintage excellent condition never used on the road Yamaha DX7. Everything works as its suppose to. I struggled to buy this state of art Digital keyboard for $2000 dollars from E.U. Wurlitzer Music and Sound in Boston in the early eighties. I used it as a midi controller in my home studio .The DX7 is very well built Keyboard and I never had any issues with mine. My DX7 has never be abused. I have not used it in years but would plug it in to check internal battery every so often over those years( it’s at 4.5 ). The sound of it really bings you back to the 80s.
“Keyboard is in okay condition on the top. Sides and bottom have significant damage. Turns on but the features are not work consistently. Missing disc drive would most likely be best for parts. This keyboard is being sold as is, for parts not working I do not guarantee I know everything right or wrong with this keyboard.” 
“Plays very well. Has some removable stickers for my favorite combinations. with cartridge and bag.”

“SEQUENTIAL CIRCUITS PRO ONE SYNTHESIZER
“Vintage Arp Axxe Synthesizer
“This synth sounds amazing! Much better than the Korg Odyssey reissue, I compared them a/b, the reissue is great, but there is something in the tone of the original that is richer and more alive. I’ve used this synth for a ton of recordings, and it sounds amazing, rock solid tuning, keybed feels great, just a great piece of gear. Only selling because I bought some more expensive vintage gear. Light and easy to transport, comes with top cover plate for easy gigging. The sliders on this can be a little stiff, with minor scratchiness but really minor for a bit of gear this old, great condition. Only small issue is the pwm mod amount slider on one oscillator has the top of the slider broken off, but you can use a key or other small bit of metal to move it to your desired amount, I used it fine like this for all sorts of studio purposes, and if you’re gigging with it, just tie a spare key to the power cord so it’s always there for adjusting that one parameter.” 
“Arp Omni I — Original 1975-1978 classic string synth. Powers on. Keys feel pretty good, sliders are not too gummy, all push buttons depress correctly and the respective LEDs for those buttons light up. I was not able to get the unit to produce sound — only static produced from the low output” 
” Good condition for age (see photos). A few scratches and chips to woodwork, but nothing major. All keys and controls work, except for the spring on the Brass Mute key (but Muting still works if switch held)
“I’m sure you know how rare and sought after these are, i was given this as payment for recording time when i still ran a studio, the owner had soldered in a power cable because he couldn’t find the connector in Tandy (They are about 50p on ebay haha) it hasn’t done any damage but i have left it as is so the new owner can take it out when they wish, the battery panel on the bottom is missing, there is one cut out of Aluminium that i will send with it, some of the yellow caps are missing and the upper and lower parts of the plastic case are not screwed together, has been sat in a cupboard since it was last turned on, moving so needs to go.

“In great condition and works as it should.
“In great shape! Does not come with power cord, will ship same day! ” 
“Ensoniq VFX SD transwave synthesizer. 61 keys. 21 voice polyphany, 12 times multitimbral, amazing drums and effects, sequencer, disk drive and an absolutely identifiable classic in 90’s electronic dance music. I replaced the internal battery about 4 months ago. They last for around 6 or 7 years in these units. The keyboard is used and shows signs of it. It is fully functional; lived most of its life in a non-smoking production studio but also saw plenty of stage use. Always adored and cared for. Classic, powerful and iconic synth, at a very fair price.”
