“There’s plenty online about the Roland Juno 60, and if you’re looking to buy one chances are you know all about it already so I won’t list technical spec etc here.
“My beloved MC 202 up for sale
“Item is in good working condition, no defects.” 
“Later version with trigger button. No corrosion. Keyboard connections re-soldered. Modulation wheel works. The switched jacks all work. Pots are mostly quiet.
“The korg itself is in pretty great shape. All the keys function & are in tune. Each of the patches work just fine & so does the modulation wheel. There is no scratches or scuffs on the body or keys. There is dust on parts of the korg but I’m sure you could remove it with ease. The D key has a small chip on the bottom of the key (as seen on the photo) but still functions as it would without the chip. Everything functions & works as it would in 1978! It also comes with it’s original power cable.”

“FB-01 Sound Generator. Eight voice, 8 part synthesizer module. It is fully programmable. No front-panel editing facilities, meaning that to edit the patches, you must use a computer editor. Half rack mount module. A few scratches, but fully functional. One button has a slight sticking issue at times.”

“this is the 76 keys Yamaha SY99.
“This was working Perfectly until a couple of days ago. If you look at pictures 6,7,8, you can see the culprit. It looks like something has burned out on the mains input circuit board, its probably not called that, sorry i dont know much about these things. Im certain this is an easy fix for somone in the know. The Synth is in worn condition but everything worked perfectly up until it decided to catch fire. Well it did smell like that !! There is no case with the DX7 so it is COLLECTION ONLY sorry about that !!!! ”

Light scratching and signs of use, but overall in very good to excellent condition. Display is clear and bright. All keys, buttons, and controls work. High end road case for the time adds to a very nice package. No cartridges. Sustain pedal included. ”
“Up for bid is the vintage 80s Sequential Circuits Multi-Trak Model#615 Analog synthesizer in excellent cosmetic condition. New battery just installed by a bay area tech. All the original factory sounds were loaded in. Tested and works perfectly! Just light marks/scratches. Comes with compatible power supply. ”
“Tunes up, and all of the keys work great, including the velocity/aftertouch. Everything else works perfectly but it is old, so it is being sold as is, no returns. You can come test it out yourself.
” It’s been recently serviced and is fully working, in perfect condition apart from some small scuffs on the wood. The External Input has been modded so that when you have something going through the Ext In you can trigger the filter and amp envelopes with the Gate In. I can ship if necessary but would prefer collection. ”
“Nice condition, fully working and includes manual .”
” Biete einen sehr alten (ca. 40 Jahre) Arp Explorer 1 Synthesizer. Der Arp lässt sich anschalten und funktioniert prinzipiell, allerdings gehen mehrere Schieberegler nur sehr schwergängig und manche Tasten triggern nicht, vermutlich müssten die Kontakte gesäubert werden. Ideal als Ersatzteillager oder Restaurationsobjekt.”
” Elektron Monomachine SFX60+ MKII+: Synthesizer and Sequencer — In absolutely new condition! Never used. I just opened the box to take a photo. I bought this as a back up to my other monomachine when I heard they were going out of production. Need the cash for home renovation now. Just like buying a brand new one. There is a reason these have reached a cult status. They sound magical!”

“The CZ-1000 was the second fully programmable phase distortion synthesizer that Casio introduced. This synthesizer, introduced in 1985, was identical to the CZ-101 in function, but used full size keys and more attractive membrane buttons. It was also somewhat larger than the CZ-101. Like the CZ-101, this synthesizer had 49 keys.

“This is my early Wasp synth – it is in very good cosmetic condition although a small piece of the plastic has come away from the front of the synth and one control knob cap has been lost. It all works and the knobs all function however it could do with a service as oscillator two does not follow the keyboard pitch and plays as a drone. Oscillator one is fine however. Even so the synth is capable of making some great lead and bass sounds. UK only. It’s delicate so pickup preferred.”
