Listed for sale on Reverb here.

"For sale is an ultra rare 32 voice 76 key Waldorf Wave Shadow! You won't ever see another one like this for sale again. There were only 300~ made and probably less than 100 have these options!"

Listed at $39,999, so $40k.

This one was spotted and sent in via Soviet Space Child.

Details via the auction

"Ultra rare 32 voice 76 key Waldorf Wave Shadow! You won't ever see another one like this for sale again. There were only 300~ made and probably less than 100 have these options!

This Wave was formerly owned by Drew Neumann and he took very good care of it. His friend's signatures can be seen on the back panel under the face plate.

There are almost no issues with this synth. There are 3 LEDs out and the display is dim - that's it. I purchased some replacement LEDs but would need to modify the circuit board to match the intensity of the originals. The owner and I decided it was not in our best interest to change them, so they have been left alone. The LEDs that are out are the -1 OCT footing for OSC 1, the -2 OCT footing for OSC1, and the HOLD LED in the manager panel. I can include the replacement leds in the sale. Unfortunately, there are no replacement options available for the back light on the display. The ELP can be replaced, but it is very very risky. Again, we decided to leave it alone.

The hydrolics that hold up the back panel fail all of the time. I just replaced them last week. Also, a new pair is included in the sale.

The original disk drive has been replaced with a 16GB USB drive.

The internal battery was replaced last week and the operating system was updated to OS 1.910. More info can be found here about the new OS:

unofficial.waldorf-wave.de/

I went through the entire self test menu. All buttons, sliders, and potentiometers are working perfectly without glitches or data skips. All potentiometers move smoothly and feel fresh. You can see from the pictures that all of the self tests came back OK. You can also see that 32 voices have been installed and are working perfectly."

Note the last image of the display below shows Board 3 not installed and a Failed message. I'm guessing that's one of the slave boards that would bring it up to 48 voices, referenced here.

Moog MiniMoog Model D SN 3718

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"This thing has undoubtedly seen it's share of action over the years. It has quite a few nicks, scratches and dents. Just by looking at it you can almost hear the countless attempts to play Frankenstein that have been tried on it. This is literally one that is going to be tough to see leave.

This Minimoog is definitely not a museum piece. It is not all original and has it's share of issues, but it is a great instrument. It is what we would call player's grade, and I would love it to go to a home where it will get the crap played out of it.

Let's get down to the details.

- First the serial number and completion signatures would indicate that it was created in 1974.
- Everything is in working order and sounds great, as I literally had put $500 into it getting it up and running less than 1 month ago. I had it serviced by Mike Borish over at Borish Electronics who is one of the best here in Chicago for old synths.
- Mike was able to replace any grommets on the keyboard so there are no clacking keys that plague these boards.
- Several pots have been changed out as well as a new power cord.
- There is a scratchy switch, but only one and it is the 440 signal for tuning. Only make a scratching noise when switched on or off.
- The keyboard is not perfectly level, as seen in the photos. It is very playable however.
- It is missing screws for one bracket on the actual wooden frame, you can see that in photo #21. The frame is rock solid however.
- Has a strange flaw in the finish on the top front panels that can only be seen in certain light, shown in photo #13
- Keep in mind that things have been changed out on this, so it can not be considered all original.

There are just a few pots that are still a little scratchy, but nothing major. I also have not had the chance to try the external controller connections so cannot say if those work or not. There does seem to be a little static from the high output jack, but the low output jack works just fine."

Synth City is a new sponsor of MATRIXSYNTH! You'll find their banner on the right of the site.

"Here's a great sounding ARP Avatar that can be used as synthesizer module over CV/Gate, the original HEX guitar pickup is no where to be found.

This Avatar was just serviced on 02/16/15 by Chicago's best, Borish Electronics.

Service notes:
-Cleaned all sliders and replaced 1 slider.
-Replaced 2 CMOS IC's related to routing and switching.
-Removed some bad tantalum capacitors.
