“Great Condition, i purchased it less than a year ago, it had just been serviced. Includes Japanese to US Converter….so it powers on and works great. I would describe the sliders as sticky. They feel tight……more so than the Roland Jupiter 6 that i had. I use a tuner on the oscillators……they are accurate for about….+-…2 octaves….” Click here to search for synths on eBay

“JX3P dual OSC analog synthesizer with original PG-200 programmer. Recently taken out of storage and it looks and sounds beautiful. All knobs, sliders, buttons have been checked and function as they should. Output is strong and clean. All voices tune. Chorus is a little noisy like the Juno-106, but works. Programmer is in fantastic, shiny condition and works perfectly, and comes with original case and programming cable.”

“KORG VC-10 vocoder.
“Korg Poly 800ii, Key contacts were all cleaned, all keys are working as they should. Sliders all work- Pitch and mod work- Part of the trim ring around pitch level looks like it is missing. Has brand new power supply. Not sure how the sequencer works, was able to see it stepping thru, however I don’t know how to use it. Unit has some scuffs here and there but is good condition for its age. Tuning slider cap needs replaced but slider pot still functions fine, just a cosmetic thing, Some really cool sounds on this unit. ” 
“Vintage 1970’s Korg Rhythm KR-55 analog drum machine. condition is Not Working and is offered for parts or repair. Mechanically, all functions appear to be working EXCEPT the bass drum sound. All other buttons, settings, switches, and lights appear to work. Cosmetically, the case has a chip and crack on one rear corner, and showing some paint wear to the control panel as can be seen in the pictures. No missing, bent or loose knobs or switches.

“Up for auction we have a Korg Poly 800 Analog Synth. Overall this synth is fantastic condition. Its been kept in side its hard case for most of its life sans the occasional gig, practice or recording session. Well loved and care for these Korg Poly 800s are awesome! Kind of like an alternative to a Roland Juno 106. Its much smaller and has a different set of sounds.”
“Smoke Free Studio. Tested and sounds great!”
“For consideration is a Korg SQD-1 Midi Recorder.
“Wonderful Korg 770 mono analog synth with two ring modulators. The VSE description does not do justice to the possibilities of this synth. Recently serviced and recapped. Fully functional with cosmetic issues: the silver caps of the knobs were removed by the previous owner and the portamento knob is not the original but a generic replacement that fits corectly (these knobs are the same used by the original MS20) There are four chips in the wooden panels (all pictured) and three very small scratches on the top panel (all pictured along a dime for reference). 3-day return policy. ”

“This is probably the most difficult sale I have ever made, in fact I have wrestled with selling the DX over many years as it has sat sadly idle in a corner gathering dust. You see that is a crime in itself as the DX100 is aguably the best DX vintage synth in my humble opinion and I’ve owned a few (dx7, dx200, TG300, TX81Z, FS1r…I fecking love FM). The reason is simple, the DX100 is light and portable, it has only 4 operators which means has just enough complexity without getting overwhelmed in the FM labrynth. Unlike other, cleaner more modern FM synths, the DX has a lot of quirk, weird envelope hangs depending on how you clip the keys that you just dont get on other synths- its unique and with a bit of grit that you just dont get on modern synths.
“According to Ray at Fair Deal music in the Bullring,Birmingham, where I bought this c.1990, this Yamaha DX7 used to belong to TheDamned.
“Original owner. Very clean, no tobacco exposure, completely functional. Includes original manual, sustain pedal, music rack, soft bag. Ground shipping paid by buyer — Continental US only”

“This item is fully functional, please see photos for cosmetic condition. Includes Manual.
“You are bidding on Yamaha DX7 classic synth. The keyboard was completely tested after sitting on a shelf for last couple years and absolutely everything works as suppose to be: all keys, display, all buttons etc- all work great. meanwhile the synth needs to be filled by sounds. We lost all patches about 2 years ago, so battery was replaced, also power cord was replaced on new one, but we never got any cartridge to fill keyboard by sounds. So I recorded some sort of spacy patch #1 just to get sound and test keys and all functions. you’ll need some cartridge or you can do it by yourself but DX series is kind of difficult to program. anyway, it’s possible and it takes time. Cosmetically the synth has some marks and imperfections here and there, but after all it doesn’t look bad for basically 40 years old instrument and cosmetics doen’t effect on functionality at all. Due an age and vintage nature the synth goes AS IS. But as I said she does works great, just fill out by sounds. we put very reasonable price. Item will be well packed and insured, see all pictures.” 
“The power of 8 DX7’s in one rack module. Amazing piece of gear. Will come with all 8 batteries of each tf1 unit replaced with brand a new battery. Also includes extra cables to wire:
“Amazing cosmetic condition for this legendary piece of Dance history. Famously known for its use in Detroit House among many others. I have tested the keyboard and it works great other than a couple keys that are semi/unresponsive. I’m sure it’s just a trigger contact issue inside (most likely due to dust). I’m listing at a great price. These are super hard to come by now especially in this good of condition!!” 
“Synth is in really good shape, few minor scratches here and there, but nothing is broken, see the pics. All keys, buttons and sliders work fine. Memory battery has been recently replaced, so it’s good for another 10-15 years. Comes with original Yamaha hard plastic case with foam inner lining, made specifically for DX21. Not the generic Gator case you may see in Guitar Center.” 
“This is a great small mono synth imported from Japan in the 1970s. It runs at Japan 100V but works totally fine in the US at 115/120VAC. I do have a step up transformer I will include for an extra $20 if you’d like.
“I checked the basic operation. There was no malfunction of the button response, and it worked normally. Basic preset sounds were output from all the keyboards.
