Roland Juno 6

“Up for sale is my Roland Juno 6 Polyphonic Synthesizer. I bought this last year thinking I was going to use it but it only used it three or four times. It sounds amazing and being from the 1980s, is in excellent condition as you can see from the photos. The previous owner kept this in the closet for decades. Everything works flawlessly. There is no lag on any of the keys. This is the same synthesizer used for the soundtrack of Stranger Things. It also comes with the original sustain pedal and a few other cables.” Click here to search for synths on eBay 

Roland CR-78 with Future Retro Swynx

“Recently serviced with a new old stock faceplate installed, cleaned and new battery lithium installed for saving tracks on the programmer.

This auction also includes the awesome Future Retro SWYNX box that also you to swing the preset loops and also acts as a pattern programmer.

Last but not least this CR-78 has been modded with a knob on the back to adjust the bass drum decay, giving you a variable sound from a stubby kick shorter than the regular cr-78 bass drum all the way to a booming 808 like kick.

The wooden box itself has some dings and corner wear which is to be expected of a 40 year old machine. This could easily be replaced with any wood of your choosing in the future.” Click here to search for synths on eBay 

Roland CR-5000

“This drum machine was working fine last year when we used it exclusively for click track in our Studio.

Unfortunately, after testing it we noticed that 4 or 5 of the buttons don’t work- It seems like that contact conductive pads (under the buttons) are dirty and in need of a good cleaning and/or minor modification.
So the unit is sold AS IS” Click here to search for synths on eBay 

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
