Kurzweil K2000S

“All functions on this keyboard work well. Pitch/bend wheel and the mod wheel work great. All dials and buttons work great. All of the 61 white/black keys respond perfectly when pressed. A few of the buttons sometimes you have to press them a 2nd time, but it’s not very often. It’s rare to find one of these K2000S’s in full working condition like this one. One of the white keys (an E note – see photos) is slightly raised 1/8″ but it plays fine and a Kurzweil tech could level it back into proper position. A few screws on bottom missing. Some scratching here and there on the case exterior (but not much and it’s mostly on the bottom) and very, very slight yellowing of the keys but that’s normal stuff to be expecting from a synthesizer of this age. Unit is very cosmetically clean. Please see description for all the great upgrades I’ve put into this thing. Unit comes from a clean & non-smoking studio environment with no kids or pets around.

It’s rare to find one of these K2000s in full working condition like this one. Some of the protective felt hairs at the back end of the keys are kind of pushed into the casing, but again, doesn’t affect the operation of the unit at all and a Kurzweil tech could push them back out.

Kurzweil 1000 SX

“This string expander module has some great string sounds, especially the low bass section and the high strings. Some of the solo sounds are just average. I’m the original owner. I used it extensively in the late 80’s through 2004 on numerous commericals and multi-media projects. I left the biz in late 2004, and it’s been mounted in a rack in my smoke-free, personal use studio since then. It’s mostly been left powered off. I don’t recall if the display ever had a backight, I don’t believe it did. However, if it did, it certainly doesn’t any more. The display is readable in a well lit room from the right angles. I’ve tested it, and it’s working great and still sounds great. It includes the original manual, which in itself is quite a novelty. I’m selling it because I’m unlikely to write music any more, and it’s time for this module to find a new home where it can be put to good use.” Click here to visit listing on eBay

Kurzweil 1000 SX

“Up for your consideration is a very clean rare Kurzweil 1000 SX String Expander, sn # 88050586. The unit was made in the USA. It powers up and scrolls through all of its functions, however I could not test it out. The unit came out of a hardly used home studio and all of the units that I got from this studio were all functioning. ” Click here to visit listing on eBay

Kurzweil K250


This Kurzweil K250 is in Very good condition for the age. Only cosmetic wear is one caps missing on the “3” slider. Currently C key is lazy but fully works. however I have a part to have that fixed by the time this sells. Includes the power supply which also works as a sustainer pedal for the keyboard itself.

This is the Last of the Fully Weighted with “real” Piano Hammer action Keyboards/Samplers

This is a loaded K250 and has too many extras to list, some of which I have no idea what they are. Can send pictures on request.

Comes with 12 RAM cartridges which are impossible to find and almost worth the price of the keyboard.

I will also include these hard to find manuals that were from Patrick Moraz’s K250. I owned his for many years ago during the time I worked with him in the 90’s.

Manuals:
* How to play the Kurzweil K250
* Kurzweil K250 Service Manual
* Kurzweil K250 – Players reference Guide” Click here to visit listing on eBay

It was pretty dusty when I got it. Headphone jack and MIDI In both work but other inputs/outputs could not be tested. Sold As Is. Buyer should know this wasn’t fully tested and the battery issue previously stated may have some affects that I’m not sure about” Click here to search for synths on eBay

Kurzweil K2500R

“This is for a Kurzweil K2000R Rack Mount Synthesizer in working condition. I’ve connected it to my K2000 via MIDI and it works as expected. I would love to keep it for the extra sounds and features, but decided to stick with a 2-tier synth setup instead of having one MIDI controlled.

AA Battery compartment is clean, but it will not ship with batteries installed. You will need three fresh AA batteries to install in the rear battery compartment (I recommend Duracell). If you haven’t done it, it’s super-easy – just turn the cap with a coin, pop 3 batteries in, recap, and turn the cap back and you’re done. Also it will not ship with a power cord, but you (like most people) may have several of these universal 3-prong AC power cords laying around in a drawer or with old computer equipment. They are very very common. If you don’t have one, you can get a short or long one depending on your needs for $10 or less retail. Sorry, but I am in short supply. ”
