Kawai K4

“Kawai K4 Digital Synthesizer 1989 – Boxed with original manual and power adapter.

This hasn’t been used in a while so some of the sliders/buttons are a bit stiff, but they did get better with use.

Generally in good condition there are some marks on top which I’ve tried to capture in the pictures.

Priced to factor in the above points.”

Kawai K5000S

“KAWAI K5000S Vintage Synthesizer Keyboard as used by Kraftwerk. Was owned by my dear friend who recently passed away. Plugged it in and it works and sounds great!. All keys play. 4 top keys are broken, but play. Seems like easy replacement if you have the wherewithal. Screen works and can be read, but not too bright. Don’t know this synth (I am a drummer), so there may be a way to adjust. Tried the pitch bend, volume, arpeggiator, and 61 included sounds, and all works well. Don’t know what the other knobs and buttons do.” Click here to visit listing on eBay

Kawai K3

“Sounds good. The volume slider may need cleaning, as it’s a bit crackly when adjusting volume, but ok once it’s set into place.

One key isn’t working. The 12th key in from the right side of the keyboard; see 7th photo in this listing.

I played around with the sounds, and it seemed fine. I’m not versed in how to use it, so I’m sure I didn’t try every feature on it; but what I did sounded good through an amp.

Being sold “AS IS.”” Click here to visit listing on eBay

Kawai K5

“Excellent used condition. No loose keys, no data cards a couple of surface scratches. I took a few quick pics to get listed. I will be putting better pics soon. I mainly used this as a midi controller, but did sometimes play the onboard sounds. Really nice 80s sounding synth. I could never fully get used to programming this thing. I have not tested ALL the outs, but i did use some of the outs to record. Please ask specifics and i will try to test / find an answer for you. More pics of certain areas etc. Hoping this will be an easy ship. Shipping may be more that listed depending, so let me calculate to your zipcode. I will work with you. Thanks for stopping by. Includes power cord. Stand not included.” Click here to visit listing on eBay

Kawai Synthesizer-100F

“An absolute classic and quite rare mono synth from Kawai

This one is in excellent cosmetic condition with barely any obvious signs of use… but it has been used and it does have some signs of age if you look carefully.

There are no big dents, scratches or battered wood on this one… it’s really good just some minor little marks that come with age.

It was serviced when I got it and it still works great but I have noticed a few keys retrigger until you play it more.

As much as I love this synth it’s just not getting used as much as it should so I have decided to let it go to someone who is going to play it more often.” Click here to visit listing on eBay

Kawai K5000S

“Kawai K5000s Additive Synth in good condition. This is IMO the best pad / odd texture synth ever made. So much potential for sound creation. The knoby section is so fun and inspiring. Check out youtube vids on it as the sound engine will blow your mind.

It all works and looks good but there are a few things to note.. The keys have yellowed over time.. it happens. Also, there are 2 or three buttons that take a harder press than the others.. off the top.. its the System button, The bank 3 button and the arpeggiator button. Most likely needs a spray of contact cleaner / deoxit. All else is great and good to go.” Click here to visit listing on eBay

Kawai K5000S

“I bought this new in 1996. It has almost never been used. Everything works. However, I have not done any O.S. upgrades on this unit, and I’m pretty sure it could use one. The current O.S. is 3.00. For me, the coolest things about this synth is the arpeggiator (it does arpeggios that I have never seen on any other synth), the real-time knobs (very analog-like control), and the awesome keyboard which is (as far as I remember) the same as the one used in the Roland A-70 controller, which is semi-weighted and feels amazing. The black keys have an almost wood-like feel.

Unfortunately I never got into programming this beast beyond simple patches using the knobs. I know that additive synthesis is very powerful but I just never had the time to delve into it. This unit is VERY CLEAN. It still has the plastic covering on the LCD. It comes with the owner’s manual, four floppy disks, and a mint Anvil case that was ordered specifically for this unit. I will re-foam the case because the foam is old. I will ship to the USA, Europe, Canada and Japan. However, I will need a postal code prior to end of auction in order to supply a shipping quote. Please ignore the default shipping amount at the top of the page. For USA ground this will cost around 100.00-150.00 to ship. Thanks.” Click here to visit listing on eBay

Kawai K1M

” Rare module version of the super awesome Kawai K1. Save yourself some desk space!
I’ve always thought these guys were kind of like a grittier Korg M1. Great digital sounds with a unique flavor compared to other options.
Plenty of videos on Youtube to hear what it sounds like + more info. All sounds seem to be the untouched factory presets.

A little dusty but works great.
Unit only. No cables and no power adapter. The last picture shows what voltage to track down. ”

Kawai K4r Project Machine

“This is for a Kawai K4R 16 Bit Digital Synthesizer Module in *Parts/Repair* Condition
Not POWERING ON…Nothing.. Not a click, not a flicker.. I could not get it to fire up with my universal/Multi-tip adapter… NO further testing performed.
I honestly think there is just a little corrosion at the POWER input or perhaps a FUSE that needs to be replaced?
The device looks to have never been opened up…
If you are good with vintage electronics this will most likely be a simple repair

NO Power supply or other pieces included.. Main device ONLY

Missing 1x SLIDER KONB…… Otherwise, VERY GOOD COSMETIC CONDITION…
No other flaws or issues to point out
NO rust, dust or oxidation
NO evidence of being dropped
NO burnt electronics smell
NO rattling or loose pieces”
