Korg Polysix

“This PolySix had the famous battery explosion, it’s been repaired, but now has an issue with tuning. I’m selling this wonderful synth as I no longer have the time or space to chase the tuning issue, and I had some emergency medical bills come up recently.”

Korg Maxi-Korg

” Classic spooky sounding synthesizer with only a few cosmetic issues, But does have several component level issues that would need to be dealt with by a technician at some point..

Had it inspected and it is semi-functional, there are some dirty pots and sliders. Did not do any service on them but Deox it or taking to a professional for cleaning would be recommended if you’re concerned. The top voice seems to fade out after a few minutes of use, expect that there are electronics issues including capacitors and other components that will need to be replaced to make this fully playable. I can create a video running through each issue that I found if you like but consider this a unit that will need service before being studio ready. It absolutely passes sound and the sound it comes out of it is amazing.

There is some confusion about these model numbers but basically this is a Univox version which is just Brandon, no functional changes from the Korg version.

What’s great about this keyboard is all the parts are available it’s not one that breaks and then you’re screwed, this is worth a full restoration at some point but big could be used right now to some degree as is.

Added a completely new set of wood panels made in the USA, you can have the originals if you like but they are pretty beat up.

This will be double boxed, fully insured, and shipped as safely as possible. This is a very important historical synthesizer and needs to arrive in the same state is left, going to work hard to ensure that.

Here are the issues:

Not the full factory set of slider caps, looks like some custom ones here. I’m guessing you could 3-D print replacements or simply go with what you have here. does not affect the ability, but if you are a stickler for original parts this one has had replacements added over the years. I’d be confident knowing you’d be able to replace all of them with reproductions considering all the different knob and slider projects that are happening these days.

The case has some rust on it pictured, nothing inside is rusting all the boards are clean. Will leave that clean up to you but basically some naval jelly and it won’t progress further.

Has 5 non-original keys. But they work perfectly and blend in with the rest of us that very well.

This is very minor but it’s missing screws in a few places, these could easily be replaced and the case feels very solid without them.” Click here to visit listing on eBay

Korg Lambda

” This is a CLASSIC 1979 ANALOG synthesizer. Probably the warmest string machine i’ve ever used. Very sad to be selling it but times are tough and money is tight.

You can find these on Reverb and similar places occasionally, but I can guarantee they are going to need to be serviced. Solder from 1979 just doesn’t keep a connection in 2022. It’s just physics. Sometimes chips go bad. This one has perfect key action, and no issues with any components. Everything is cleaned and resoldered and checked by a professional.

If you’re into vintage analog synths and string machines.. this is your best best. You may get lost in the warmth and depth of the chorus on this rig. ” Click here to visit listing on eBay

Yamaha TX216 with 4 Yamaha TF1 Modules

” Yamaha TX216 Rackmount with 4 TF1 modules installed. Brand new battery installed on each TF1 module.
I tested the unit and each module after new battery install for power, numeric display, midi send / receive function and tone generation via XLR outputs and all are working great. Power supply is quiet no buzzing. Due to the age of the unit being sold as is. ”

Yamaha SY-1

“Yamaha’s first analog synthesizer available in America. This one is in wonderful cosmetic shape, just needs a cleaning and tuning procedure otherwise it’s ready to go.

I would plan on 1 to 2 hours of time to get this studio ready,”

ARP Quartet

“Vintage ARP Quartet 49 key synthesizer. Powers on and some keys play, but this keyboard is in rough shape and is going to need some love to be fully functional again. I didn’t test it too thoroughly, but it looks like the Piano, Brass and Organ sections work, Strings do not. Some keys do not respond (dirty contacts?) and one key is damaged. Sliders are dirty and one is missing.” Click here to visit listing on eBay

Kawai K4

“Vintage KAWAI K4 16-bit Digital Synthesizer Keyboard.

Late 1980’s Kawai K-4 for your 1980’s tribute band, nostalgic rock band, 1980’s movie soundtrack sound source or similar. This was Kawai’s version of the popular Roland D-50. It has very usable organic sampled sounds, strings, pianos etc. The keyboard powers up and plays but the B2 key needs contact cleaning and won’t play until that is done. I also have ROM cards for it as well to add more programs/sounds. I have an old case for it as well that I can include. The case needs a new handle that’s easy to replace.”

Oberheim OB-Xa

“I am the 2nd owner of this. I have had it for 20 years, never gigged, just home use. All caps replaced years ago. Midi added. There was some feature put in by the original owner that I removed so there’s a small row of plugged screw holes on the top left of the unit.

I had the anvil case made. It looks near perfect with only a couple of small scratches to the top of the case. Working well, awesome sound. Programs fine. No problems to speak of. ZERO corrosion or paint chipping. This one is probably the cleanest one available right now. I never used the MIDI and cannot say if it works or not, cause I don’t know. Local pickup available in Oceano, CA. next to Pismo Beach.”

Casio CZ-101

“This Casio CZ-101 is tested and working great. It’s used and in very good condition. A previous owner wrote “9V” on the far right of the keyboard.. to remind them what power supply to use I guess.

That being said, it is tested with a 9V power supply (not included) and works great. I didn’t test it with batteries but the compartment looks clean so it should be good to go.”

Moog Micromoog Project Machine

“This item came from an estate. It does work. Sounds are abundant, The pitch ribbon needs to be replaced, also the power light is pushed in. I used contact cleaner on the controls and it helped greatly. I am not the most knowledgeable when it comes to these units, so it is being SOLD AS IS. All the key operated. There is some waves in the plastic, however, it still seals. There is an area of vinyl that’s pealing up.”
