Korg Polysix

“Cosmetically it is not so pristine. It is structurally sound, but you can see in the pictures that there are chips in the wood, the panel is scratched, and there is a plastic button missing, which I am sure you can source, and the underlying switch works.

All keys work but a few keys make a minor clacking sound (physically, not through the output). The keybed Is not perfectly level and could use a little love, but you do not really notice while playing and likely cheap and easy should you choose to address it. Despite the cosmetic imperfections, it is very much working, playing, calibrated and ready to do its thing.

Of special note is the bucket brigade ensemble effect which is a large part of what makes this a sought after board. No digital board will really pull that off.” Click here to search for synths on eBay

ARP Pro Soloist

“This keyboard is in great condition especially cosmetically, it almost looks new. All sounds and functions work on it including the “touch sensor effects” however the keys and the sliders are very stiff and one slider is missing a cap. The stiffness is bad enough that it will need to be addressed so the price reflects this. Also when adjusting the volume sometimes the sound will go out but will come back once the slider is adjusted to the “right” spots. I had posted this earlier stating that it didn’t work in other ways but it turns out it works great I just had my headphones plugged into the wrong output. (Different outputs than I am used to, this thing is old school!)” Click here to search for synths on eBay

Oberheim OB-8

“This is an early model Oberheim OB-8 analog synthesizer and does not have factory MIDI. The unit is in excellent functional shape. It has a small dent in the rear of the unit shown in the photos. I’ve never had any issues with the presence of this dent. I purchased the unit with this issue and the previous seller did not have issues either. I have replaced the entire keybed with new contacts and thoroughly cleaned the unit. The volume knob sometimes has a slightly scratchiness only while turning when not in use for a while which is normal for its age. All buttons and knobs work as far as I can tell. It has all the original patches as far as I know. There is nothing like the sound of an OB-8! I have purchased many newer analog synthesizers and just don’t have room for this monster. It has a lovely warm 80’s sound! I “Do Not Ship Internationally” and only ship to the lower 48 states, Please No Inquiries. The unit is being shipped “As Is” because of its age. The unit has many internal boards that have not been removed so it should be fine to ship.” Click here to search for synths on eBay

Oberheim Strummer

“Tracking down vintage gear? I’ve had this in my closet boxed and now putting it on eBay. The “Strummer” listens to chords played on your MIDI keyboard and plays them back to your MIDI sound source (Synthesizer or Sampler) just as they would be played from a guitar. Not only will the chord voicings be correct, but the chords can actually be “Strummed!” With the “Strummer,” you can even change the speed and direction of your “Strums” just by changing the way you play your MIDI keyboard. Also, “Strummer” has the ability to distinguish the difference between chords and single notes, allowing you to send chords out on one MIDI channel (Distorted Guitar Sound for example) while your single notes are sent out on a different channel (i.e. Solo Sound). Your keyboard may have a great guitar sound, but can you play a great guitar part? Yes. The Oberheim Strummer will transform your keyboard playing into a stunning and convincing performance featuring realistic guitar articulation. It comes in the original Oberheim box with manual and ac adaptor.” Click here to search for synths on eBay
