Yamaha CS60

“This synthesizer has been owned by one person and has obviously been kept in incredible condition. Every switch and dial works perfectly, and the sound is magical. This piece is good enough to put on display at a synth museum.

I live in CT and am a pilot and aircraft owner and rather than have it shipped to me, I picked it up and flew it back. And if I can, I’d be willing to fly it out personally to any local airport east of Chicago for the price of shipping (will cost me more in gas alone), if we can schedule a date. This synth means that much. If for whatever reason we can’t coordinate a date, it will be meticulously packed and insured if shipped.”

Korg MS2000B

“This synth has been kept in my smoke free and pet free studio for about 4 years. It’s a great synth but I’m trying to downsize a bit. I really love this synth for its 90’s character and the mod delay feature. Also the vocoder is great too. Comes with power supply.” Click here to visit listing on eBay

Korg MS2000R

“This system Looks good we are unable to properly test it. I do not know how to work it. But the lights come on and off as they should. The number 7 button for the amp will not light up when pushed so I dont know if it has to be hooked up to a amp before it will light up. All knobs feels like they turn as they should not loose or play in them. The digital display lights up and displays as it should when switched to different programs. [See Pictures] This unit is sold as is untested. There is 2 knobs on the Patch 3 and patch 4 that is missing. We are looking thru our scrap electronics to see if we can find the right ones for it. So they may not be there.” Click here to visit listing on eBay

Korg EX-800 with Hawk 800 Uprgrade

“The Korg EX-800 is an 8 voice polyphonic synth and this one is in really good shape (which I paid £300 for). This synth has been modified and includes additional knobs for – Filter cutoff, Resonance, pseudo FM amount , Noise + a switch to choose a 12dB or 24 dB filter. The desktop version is very hard-wearing with its metal case, also giving it a good weight.

I have also modified it further by installing the HAWK-800 upgrade (the kit costs about £100 to buy + my time to install) which adds an unbelievable amount of features to the original synth. If you go to https://www.hawk800.com/ this explains in detail all the extras you get from it.

I have included a picture of some software Joe Mattiello developed to control this synth using Abelton/MaxForLive which shows quite how many features are now available. You can also set up a midi controller to change parameters as well. It allows you hook it up to your computer and change the parameters from there instead of having to use the buttons on the front. Abelton seems to be the favourite but other DAWs can send midi to it as well.

I have plenty of experience with soldering and fixing up synths having built most of my modular synth. The Hawk-800 has worked without a any problems for 8 months now so I am confident about the robustness of what was a pretty advanced installation. I will also be including the AtomaHawk upgrade that I have not installed (see bag of components in image). This allows you to control the filter and resonance knobs on the front via the computer (using LFOs as well).”

I am the original owner of this beauty, and I have kept it in excellent working condition. This unit has lived in my recording studios for it’s entire life and has been used on MANY Chicago House, Techno, Hip-Hip, and even Rock records.

ARP Axxe

“Daher müssen alle Geräte gehen, mit denen ich zu selten oder schon länger nicht mehr arbeite.

Zum Verkauf steht ein ARP Axxe MK I.

Ich habe den Synthie vor fast 30 Jahren gebraucht gekauft; leider steht er seit Jahren hauptsächlich rum und wird so gut wie nicht mehr benutzt. Daher muss er nun Platz für was neueres machen.

Optischer Zustand:
Ziemlich gut für das Alter. Die Holzseiten haben minimale Macken.

Technischer Zustand:
Alles OK. Die Fader haken und kratzen teilweise ein wenig und sollten mal gereinigt werden.

Ebenfalls nicht unwichtig: Zumindest während meiner Zeit ausschließlich ein Nichtrauchergerät.”

Kawai K5

“Up for sale is a vintage Kawai K5 in very good condition. I am adding the case as well. This keyboard has had one owner and has been very well taken care of. I have 4 keyboards and am painfully parting with this one because I need the money. The only issue is that it no longer has a backlight.” Click here to visit listing on eBay
