Also see the Model 101 vocoder here.

"Up for sale is a super rare 10-band vintage analog vocoder built by E.EW. (Eizuka Engineering Workshop) possibly in the 80s in Japan.

Seems like this has the same functions as the E.E.W. Model 101 vocoder, however, there is no model name printed anywhere and so it could possibly be a proto-model or a custom-made unit.

The unit appears to be working as it should, with all the knobs and switches responding and working fine to the best of my knowledge as being tested by a guitar. There are slight scratch noise on some of the knobs due to the nature of these vintage synths, which could do with some adjustment/servicing if required.

Cosmetically the unit is in nice condition for its age as you can see. There are some wear and light scuffs marks here and there as pictured, but nothing serious. I'm including plenty of pictures of the actual item so you can see exactly how it looks.

Power cable included.

**This unit was made for the Japanese market which runs on 100 volts. You will need a stepdown voltage converter for 120V - 220V regions."

Mystery Model 101 Vocoder

This one is in via supporting member, David Bivins who currently put it up for sale on eBay here.

He picked it up used at a Japanese auction site, and unfortunately does not know the history behind it. I've never seen it before. If you know anything aobut it, primarily who made it and when, feel free to leave a comment at the bottom of this post.

via David in the listing: "Very cool looking vintage 10-band vocoder. Does not work and is missing parts - for one thing, there is no power supply! I purchased it this way and have decided I do not have the time to devote to repairing it."

You'll find some pics of the inside below.

Update: it was listed on a Japanese auction site as an E.E.W. Model 101 Vocoder. E.E.W. stands for Eizuka Engineering Workshop 永塚策英 Japan Yokohama according to @analogjimmy.

via Wikipedia Japan: "From this work, Ito has released a wind synthesizer called 'TAKECON-1', which is a special order made by EIZUKA ENGINEERING WORKSHOP, as 'OMENS OF LOVE' (using TAKECON-1 + TAKECON-1 sound source) and 'PRIME' (TAKECON-1 +). Used in TAKECON-1 sound source)."

If you search online for Eizuka Engineering Workshop you will find a few additional references.

Directly below is a video of the TAKECON-1 mentioned above. It's a Lyricon wind synthesizer according to @analogjimmy.

"I've gone down this rabbit hole before. EEW made some wind synths and utility rack gear. Seems like it was a small company. The name I've seen associated with EEW is Sakuhide Nagatsuka but I have no idea the relationship. Some EEW gear was apparently sold via retailer Ishibashi."

According to that thread, it's possible Sakuhide Nagatsuka passed away based on some online discussions.
