“Offering up this analog gem. It’s been in the family for decades, but hasn’t seen much use lately.
I have extensive electronics experience, so I serviced it. I cleaned the controls, performed the battery life modification, and installed a new Energizer Lithium battery. Should last 10 years before it needs service again. Other than that it is unmodified and it is a revision “A” board. The patch memory was lost when the battery died, but I programmed a handful of sounds to test out the features. There is a lot of information regarding the original 100 presets online if you are looking to restore the factory samples.
Everything except the “tape drive” functions were tested. All controls, MIDI and audio I/O are 100%.
The power cord insulation is cracked as noted in the pictures. There are scratches on the bottom and a ding or two on the control plate. Otherwise it is excellent!”

“I’m the second owner of this unit. During my ownership it has only been used in my smoke free home studio. Original owner claimed the same and I’ve found no evidence to believe otherwise. Minor rack rash as shown in photos otherwise excellent physical condition. Works perfectly. Comes with screws and power ribbon. Does not have original box but will be well packed for shipping.” 
“In excellent condition. Fully working – very minimal rack rash. Very unique and rare module that uses the actual “speakjet” chip. Has a synth mode – so it produces tones too, not just words/phonemes – it’s more versatile than you might expect – produces chords as well.” 
“Hello. Up for consideration is a Casio CZ-101 Vintage Synthesizer Keyboard ~ FREE SHIPPING
“It is EuroRack synth voice module of Macbeth Studio Systems.
“Only selling because I have two – this one listed here just brought up to spec at EMS very rare DK1 Cricklewood keyboard includes original EMS zipper bag- , Jones connector lead to interface to EMS synths and instructions
“It has rich, complex, creepy, and dark digital sound that can be modified with different effects and envelopes. You can also layer sounds. If you just start pressing random voices and modifiers you end up with sonic gold more often than not. These were my secret weapons in the 90s back when finding authentic complex keyboard sounds was harder to do. It records very well.
“Up for auction is my Oberheim Matrix-6 synthesizer. I’ve used this synth in my smoke-free home studio for the past five years, and I know it inside and out. This synth is in immaculate cosmetic condition, and it sounds amazing. The mod matrix really allows for the creation of much more unusual and interesting sounds. All buttons, volume slider, pitchbend levers, jacks, and synth functions work perfectly.
“This lil’ synth is practically new, and hasn’t been used very much at all. It comes with a screen protector, a decksaver (the plastic cover that protects the knobs), a USB charging cord, and a nice little case for you to transport it anywhere you like!” 
“Excellent cosmetic and working condition. I bought this at a bad time, lost my job. I used it only twice.comes with 20 patch cables and power supply.” 
“KAWAI K-4 Vintage 16 Bit Synthesizer 61-Key Keyboard. Made in JAPAN – 1989 – nice working condition for nearly 30 years old – aftermarket power supply ships with synth! These are becoming more and more sought after!” 
“Rare Kawai SX-240 analog synthesizer up for auction! Released in 1984, this 8-voice polyphonic synth has 2 analog DCOs and one sub-osc. Stackable in poly-8, poly4 or mono mode for a really big sound. Great for leads, bass, brass, drones, pads and strings, plus add on-board ‘ensemble’ (chorus) or ‘brass’ (ring mod) effects.
“This is the legendary Oberheim OB8 in pristine working condition. Cosmetically there are light signs of wear (all detailed in pics), most significantly a scratch on the upper right of the top casing, light scratches on the sides and back and some scuffing by the arpeggiator. Great condition for how old this keyboard is.
“This synth is in excellent condition. All knobs are brand new from the factory in Germany($100), volume pot is brand new as well. This is a 10 voice polyphony unit I love this PPG like synth but I really don´t use it,so I rather sell it to a person who needs it. This unit works as it should , no issues at all ! It works with a 12 volts DC adapter, not included, sorry !” 
“Overall very good condition, some scratches to the external edges of the case (shown) but otherwise all is fine. Only gigged twice. Selling as I don’t use it as much anymore, and due to financial need. I am very excited though that my trusty modular system will be acquired by a real enthusiast. It is quite a large system and very heavy so only post to the UK.
“Jen SX1000 in working order.
“Make Noise Maths rare original lightning bolt panel with the newer edition knobs.
“Funky little Jen synthesizer received from a clearance. Not entirely sure of the complete workings of it but seems to work absolutely fine. All controls do something & handily has these cardboard guides to tell you where to turn the knobs to which helps. Couple of caps missing & controls may need a clean but in good general condition. No buy it now price as not sure of worth.” 
“90% – Very Good Condition : Basically Clean, might have some deeper scratches, pick wear or missing finish. Nothing real serious, no cracks, or other flaws.” 
“This Moog Source is in excellent condition. We are the second owner, it has lived it’s entire life in the Los Angeles area and is in excellent condition inside and out. It is exceptionally clean inside as it’s never had any repairs and has only been calibrated by qualified folks over the years. It has the Encore MIDI kit professionally installed. The original membranes are in excellent condition, however in respect of full disclosure the top membrane is starting to go bad where the connectors pass through the top panel (by the upper left corner). Sometimes you have to press that area to make sure all the connections are made so that it operates properly. The unit comes with a new switch membrane panel from Synhouse, but we’ve never installed it as the original membrane is visually perfect and usually works. If the buyer wants it installed at purchase we can install it before shipping. Otherwise the extra panel overlay will be included with the Source ($245 value). ”
” Moog “The Rogue” synthesizer for sale. In very good to excellent condition. Interior foam removed by previous owner. All keys, sliders, knobs and mod wheels working properly. I have only used the audio out jack so I cannot verify the condition of the others.

“Used. Works great. Some significant cosmetic wear.” 
“Roland Juno-106 Programmable Polyphonic Synthesizer for sale.
“For sale my Jx3p. I bought her in 1988 and still sounding amazing. She has been gigged in the early 90s. She is in full working order but has a few marks and cosmetic scares as you can see in the photos but nothing that effects the working of the board. ” 
” The classic Roland Jupiter 6, in great working order with minimal cosmetic flaws. Fully functioning, smoke free studio. Keys all work beautifully, good action and no issues. All LED lights, sliders, buttons and knobs all in great condition.
