Yamaha B200 Synthesizer (1988)

WOLF retro DESIGN REVIEW. 5th July 2018

A retro review looks at products that are at least over ten years old from a present-day WOLF design perspective. While the technology and fashion of the period influence design, and are taken into consideration, great design ideas will transcend their eras to be timeless.

Interesting and factual information may be provided, but our review aims to deliver insight from the perspective of a designer’s mind and eyes.

Product Focus
As with most reviews the focus is on the design and its evolution with musical keyboards. The functioning systems and sound quality are not necessarily not considered.
Product description
The B200 was the very first of Yamaha’s B series synthesizers and was essentially a Yamaha YS200 synth with speakers and a more subdued appearance. The B200’s most notable characteristics are the built-in speakers that make it seem like an amateur home keyboard. It was however in a category above the home keyboards yet lower than the professional range at the time (the DXII series). Yamaha’s B series is a less professional music workstation that was primarily aimed at the Japanese market for beginners and intermediate keyboard players.
Price and Availability.
These were more popular and available in Japan where it was called the “EOS B200”. It was the only “B” model sold outside of Japan which is why 220V versions are available. Today your average second hand unit will be around $300 Aust. A mint specimen outside of Japan will be rare so be prepared to pay as much as $400. If you don’t mind extending your budget further you could import a nice one directly from Japan with original case. They tend to be readily available in Japanese second hand music stores but would obviously be 110V and require a step-down transformer.
Additional information
From 1988, when the B200 was released, through to 2007, Yamaha held an EOS contest judged by notable Japanese musicians, bringing attention to the field of synth-based music production. The EOS series found favour with teenagers and women in their twenties, with product planning and marketing working together to develop the instrument, heralded an era in which design also worked to respond to a range of different requirements.
ReviewFirst impression/ Delight
There is a certain amount of excitement or anticipation about this machine because it looks so different. The B200 looks as unconventional today as it would have in 1988. At a time when technology was rectangular the B200 was far out of the box with hardly a straight line in sight. It’s almost as if the brief specified to avoid squares and use as many circles as possible. The speakers, buttons, pitch and modulation wheels are all perfect circles. Even the screen has rounded corners. The large speakers that take up space may have inspired this line of thinking in an effort to disguise them.Exterior Design ReviewThe buttons on the face plate are neatly arranged with plenty of space. In our view there is possibly too much space to make the face plate feel rather bland or empty. They are sized and shaped a bit like Mentos. Their design is well considered with even a shadow line detail around them.  The pitch and mod wheels on this version form two halves of a sphere, which looks interesting but can be a bit awkward to use. Thought was given to designing this unit to appear slimmer from the rear and sides. The sides cantilever out about an inch with two-tone effect. The top face of this unit has a textured flat grey paint while the bottom half is a more standard dark grey plastic finish. All corners a well rounded and the sides have subtle curves. Craftmanship.The textured surface paint does help to make this unit feel less plastic like than it really is.  It’s durable but after 3 decades many will have scuffs, chips and scratches. It’s not built for live gigs and Yamaha would have known that anyways since this was not intended for that purpose but rather to look nice in a home studio. The buttons, keys, screen and modular wheels are all solid as standard with Yamaha to make this a machine built to last. You would just need to be careful not to stain or scratch the body as it’s a type of plastic and colour that would be very difficult to repair or touch up.


FUNCTION- Experience.

We found the buttons don’t feel nice to press. Despite their craftsmanship there just seems to be cheapness to the way they feel and click. With too much space on the face-plate we found that much of the initial anticipation from its unique design gets lost in the lack of controllers and “Things to do” on the front panel. The cantilevering ends feel nice to hold and make this unit easy to carry.

Desirability / Collectability

From a collectability perspective the B200 is confident in its position because it is the first in its range. It’s looks are unique but not necessarily pretty. Beautiful design however is not necessarily good design. When compared to all the subsequent B models we felt it had the best overall design balance. In our view the B200 was a brave design decision with good effort. The colour is probably a bit dull given that the shape was so radical for the time. We think Yamaha could have marketed this unit with multiple colour options or even artistic graphics splashed across all that empty space.

Original Brochure


It’s a cute and interesting synth from our design perspective but by todays standards it’s nothing to shout about.  If you find a mint one for a bargain, it is still a great sounding machine to have with the convenience of built in speakers. It’s a simple and easy keyboard to play but you’ll find plenty of newer models able to do a whole lot more for similar dollars.
