“Kawai K4 16 Bit Digital Synthesizer Keyboard No Power Supply. Condition is Used. Includes soft case – but as you can see in the pictures, one side of the shoulder strap for the soft case has broken off. The keyboard will NOT power on – but I do not have the power cord.

“Kawai K4 16 Bit Digital Synthesizer Keyboard Works Great No Power Supply. Condition is Used. Includes soft case – but as you can see in the pictures, one side of the shoulder strap for the soft case has broken off.

This great sounding keyboard is in excellent working, excellent sounding shape. The power supply is not the original, but it works perfectly with this piano. The keyboards keys are all working and the selector buttons are switching through the various preset sounds as they should be. The keyboard shows some typical signs of cosmetic wear from use, but still makes a great overall impression.” Click here to visit listing on eBay

” Vintage Kawai K4 Digital 16bit Synth from the late 80’s.
Synth looks good with some minor wear, all keys seem to work(one has minor chip) see pics.
Synth boots up but only has one sound, i am guessing someone changed the battery and lost the factory presets and never loaded them back on, a easy fix if you know how and a free download.
The biggest issue is the Volume slider has a lot of noise, it works but not right, maybe just needs cleaned but may need to be replaced.
If you are handy with these here is a chance to get a great deal on a very cool vintage synth.” Click here to visit listing on eBay

“Kawai K4 synthesiser, does need some attention. There are 3 sound cards with the keyboard, although I think there are only sounds on 2 of them, there also only appears to be 1 sound when you play the keyboard with no card in, (may need the factory sounds reinstalling). There are also some keys that do not work, and these are marked on the photo’s. I am fairly certain that I have the user manual, but will check and update this listing, (it is freely available on the internet if I haven’t). There are also a couple of the weights missing from the underside of the keys, (again shown on photo’s), I may still have them, but not guaranteed.” Click here to visit listing on eBay

“The only thing I can find wrong with this keyboard is that the F# key above middle C sticks. There is no additional software or manual included. It does come with a power supply but it is not the original one. Not sure when these were made but it is in very clean condition as you tell by the pictures. There are few light scratches on the bottom of it.” Click here to visit listing on eBay

I bought this on Ebay a few years ago and I recall it did not come with rack ears or manual, neither of which bothered me. As you can see I simply set it atop other rack modules and it worked great. I downloaded the manual on .pdf (100 pager!) and will include that with the synth. Also included is the original power supply. I have two RAM cards for sale in other auctions that were used with this K4r.” Click here to visit listing on eBay
